Java Loops

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

Java Loops

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

Java for Loop

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

Syntax:-

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.
