Java Loops

In this tutorial you will learn about the Java Loops and its application with practical example.

Java Loops

Loop statements are used to execute the block of code repeatedly for a specified number of times or until it meets a specified condition. Loop statement are very useful to iterate over collection/list of items or to perform a task for multiple times. In Java, we have following loop statements available-

Java for Loop

The for loop is used when we want to execute block of code known times. In Java, basic for loop is similar as it is in C and C++. The for loop takes a variable as iterator and assign it with an initial value, and iterate through the loop body as long as the test condition is true.

Syntax :-

Example:-

Output:-

java_for_loop_example

Java While Loop

The while loop will execute a block of statement as long as a test expression is true.

Syntax:-

Example:-

Output:-

java_while_loop_example

Java do…while Loop

The do…while statement executes loop statements and then test the condition for next iteration and executes next only if condition is true.

Example:-

When we run the above java program, we see the following output –

Output:-

java_do_while_loop_example

In this tutorial we have learn about the Java Loops and its application with practical example. I hope you will like this tutorial.
