Looping Constructs

For Loop

-A for loop is a repetition control structure that allows you to efficiently write a loop that needs to be executed a specific number of times. -A for loop is useful when you know how many times a task is to be repeated.

Loops In Java

-There may be a situation when you need to execute a block of code several number of times. In general, statements are executed sequentially: The first statement in a function is executed first, followed by the second, and so on. -A loop statement allows us to execute a statement or group of statements multiple times and following is the general form of a loop statement in most of the programming languages.

Java programming language provides the following types of loop to handle looping requirements :

-While loop -For loop -Do..While loop

Do..While Loop

A do...while loop is similar to a while loop, except that a do...while loop is guaranteed to execute at least one time.

While Loop

A while loop statement in Java programming language repeatedly executes a target statement as long as a given condition is true.

Enhanced For Loop

As of Java 5, the enhanced for loop was introduced. This is mainly used to traverse collection of elements including arrays.
