A curious thing happened during the recent Australia-Pakistan ODI in Brisbane. In the fifth over, Mohammad Amir bowled a peach of a ball to David Warner. With the seam canted towards slip, the delivery started on the line of middle stump before swinging away, evading the left-hand batsman's attempted flick to leg by some distance, before clipping the bails. It was an exquisite, almost unplayable outswinger, behaving much as the bowler intended, and defeating a highly capable batsman in prime form.

It is the delivery that followed, however, that is more interesting, at least for the purposes of this article.

This time it was Steven Smith taking strike and facing the first ball. The ball left Amir's grip with the seam pointed in the same direction as the previous delivery, apparently intended to move in to the right-hander. It swung away instead, and Smith, walking into an off drive, edged a catch through to the wicketkeeper.

"What a delivery," remarked one...

AWT is a Java interface to native system GUI code present in your OS. It will not work the same on every system, although it tries.

Swing is a more-or-less pure-Java GUI. It uses AWT to create an operating system window and then paints pictures of buttons, labels, text, checkboxes, etc., into that window and responds to all of your mouse-clicks, key entries, etc., deciding for itself what to do instead of letting the operating system handle it. Thus Swing is 100% portable and is the same across platforms (although it is skinnable and has a "pluggable look and feel" that can make it look more or less like how the native windows and widgets would look).

These are vastly different approaches to GUI toolkits and have a lot of consequences. A full answer to your question would try to explore all of those. :) Here are a couple:

AWT is a cross-platform interface, so even though it uses the underlying OS or native GUI toolkit for its functionality, it doesn't provide...

A combination of Shane Warne and Australia's fast bowlers brought England crashing to defeat in the second Test in Adelaide.

One bowling weapon that aided their cause was the same one used so effectively by England 18 months ago.

This time, Brett Lee found reverse swing in the heat of south Australia.

But what is swing? And more to the point - what is reverse swing and how can certain bowlers harness it so potently?

We explain the theories.

WHAT IS SWING?

The cricket ball often moves in the air towards or away from a batsman when a pace bowler is bowling.

It is this deviation most fast bowlers strive for because of the problems it causes batsmen.

Swing is all about aerodynamics, more of which is explained in the next section.

Batsmen are used to facing orthodox swing - which happens when the ball is still relatively hard and new in the first 10 to 15 overs.

However, over the past 20 years fast bowlers...

Answer / tushar

1.Swing is also called as JFC’s (Java Foundation classes)
and AWT stands for Abstract windows toolkit.

2.AWT components are called Heavyweight component and
Swings are called light weight component because swing
components sits on the top of AWT components and do the
work.

3. Swing components require javax.swing package where as
AWT components require java.awt package .

4.swings components are made in purely java and they are
platform independent whereas AWT components are platform
dependent.

5.we can have different look and feel in Swing whereas this
feature is not supported in AWT.

6.Swing has many advanced features like JTabel, Jtabbed
pane which is not available in AWT. Also. Swing components
are called "lightweight" because they do not require a
native OS object to implement their functionality. JDialog
and JFrame are heavyweight,...

Swing bowling is a technique used for bowling in the sport of cricket. Practitioners are known as swing bowlers.

Swing bowling is generally classed as a subtype of fast bowling.

[edit] Physics of swing bowling

The essence of swing bowling is to get the cricket ball to deviate sideways as it moves through the air towards the batsman. In order to do this, the bowler makes use of four factors:

The raised seam of the cricket ball. Asymmetry in the ball caused by uneven wear of its surface. The speed of the delivery Their action

The asymmetry of the ball is encouraged by the constant polishing of one side of the ball by members of the fielding team, while allowing the opposite side to deteriorate through wear and tear. Over time, this produces a marked difference in the aerodynamic properties of the two sides.

Well I get the answer of the question when I was in class 11th. First:- The principle is applicable if their is smooth or turbulent flow on both sides of the ball i.e. similar viscosity. There is 2 principle regarding the swinging of the ball. If the ball is thrown at low speed both sides of the ball have smooth flow. If the ball is thrown with high speed, both sides of the ball have turbulent flow. There are also speed ranges in which flow may be turbulent or smooth. These speeds are given by Reynolds number. A medium pacer uses this middle critical region of speed, where the flow may be smooth or turbulent, to swing the ball. The rough side of the ball has turbulent flow whereas the smooth side of the ball has smooth flow in this critical range of speed. Hence, air on the rough side fails to catch up with the air on the smooth side creating a low pressure region on the rough side. This tends to deviate the ball on the rough side in normal swing. Reverse swing can...

Both swing and seam refer to the deviation of cricket ball from a straight line path and is usually used by fast/ fast medium bowlers.

Seam movement is a sharp movement caused by the seam of the ball hitting imperfections in the pitch.

But swing is curvy movement of the ball in the air (much like a football bending in the air) due to aerodynamics.

The seam on the ball plays a crucial role in both.

(There is an article on cricinfo as to how a cricket ball swings). .
The science of swing bowling

Skilled bowlers like Wasim Akram, James Anderson et al would be able to get swing on most situations although they may be able to control only the direction of the swing but not the amount. Now I say most situations because even for skilled bowlers under some situations (dry ground with sun out) the ball does not swing at all. Also, there is a belief among bowlers that some cricket balls just do not swing and they will try like hell to get it...

Yes this is the most important concept for especially fast bowlers, if you understand the concept you can experiment your skills on the ground, on which it can result you in more sophisticated fast bowler.

The first and most basic thing is the swing of the ball happens in the air not when it hits the pitch or ground, and the seam of the ball happens when, after the ball actually hits the pitch.

The swing of the ball depends on the shiny sides of the ball, moisture in the pitch, air, how do you grip the ball but not on seamy part of the ball, which implies even when the ball becomes old I mean when the ball becomes soft and rough where the seamy part of the ball loses its character, then even though the ball still swings like late swings and reverse swings.

And similarly the seaming deliveries depend on seamy part of the ball, how do you grip the ball, nature of the ball, nature of the pitch ( I mean the pitch should have the gripping nature so that the seamy...

Seam bowling is a phrase used for a bowling technique in cricket whereby the ball is deliberately bowled on to its seam, to cause a random deviation. Practitioners are known as seam bowlers or seamers.

Seam bowling is generally classed as a subtype of fast bowling, although the bowling speeds at which seam can be a factor include medium-pace bowling. Although there are specialist seamers that make deliberate use of Off cutter and Leg cutter at the expense of bowling slower than regular fast bowlers, most bowlers employ the seam to some effect and so the terms "seamer" and "fast bowler" are largely synonymous.

Physics of seam bowling[edit]

A cricket ball is not a perfect sphere. The seam of the ball is the circular stitching which joins the two halves of the cricket ball. Hence, the seam joining the pieces of leather is circumferential and the stitching is noticeably raised. If the ball is bowled in such a way that the seam hits the pitch when it bounces,...

Seam bowling

Seam bowling is again a rather confusing category in isolation, as any fast bowler will make use of the seam on the ball in some way. However, defined strictly, a seam bowler is anyone that bowls the ball directly onto its seam to cause deviation off the pitch.

The logic for this is easily understood. A cricket ball is not a perfect sphere – the stitching on the seam (which joins the pieces of leather) is raised and the irregularity means that a bowler can create sideways movement if it bounces on the pitch. The stock delivery for the seam bowler is therefore one with the seam upright and the ball moving around its horizontal axis to ensure the seam faces the batsman vertically at all times.

The minor deviation which can result is often the difference between a nick from the batsman and a regulation defensive stroke. Australia’s Glenn McGrath, in particular, was a master at this art and, generally speaking, seam bowling is the preserve of medium...

To get the best possible chance of any sort of movement in the air or off the pitch, a fast bowler should grip the ball "seam up".

Learning this basic grip will get your wrist behind the ball, an essential starting point for any bowler.

With the seam vertical, the ball is held in the fingers, resting on the third finger and thumb, with the middle and index fingers either side of the seam.

Try to land the seam as straight as possible on the pitch.

This will give you a much greater chance of any sort of movement, especially with a brand new cherry in your hand.

SEASONAL VARIATIONS

You'll find some days the ball will swing and seam almost every delivery, while on others it will do almost nothing.

This is because movement relies on four key factors:

The bowler: Some bowlers have bowling actions which naturally help the ball to swing in the air. A good side-on action will help a bowler to swing the ball away from the bat. ...
