While Loop in Java

In programming, looping is a feature that helps to repeat a set of instructions/functions as long as a certain condition is true. There are three ways to create loops in Java, each with their own syntax and way of checking conditions.

One of the ways is called a "while loop". It's a way to repeat a block of code as long as a certain condition is true. The syntax for a while loop is:

java
while (boolean condition)
{
   loop statements...
}

A while loop starts by checking if the condition is true. If it is, then the statements inside the loop will be executed. If the condition is false, then the loop will end and the program will move on to the next statement after the loop.

The while loop is called an "entry control loop" because it checks the condition before the loop starts. The loop will keep executing as long as the condition is true. In the loop body, we can update the value of the variable being processed so that it will be ready for the next iteration of the loop.

Once the condition becomes false, the loop will terminate and the program will continue with the next statement after the loop.
