JAVA : What is a while loop in Java?

A while loop in Java is a control structure that allows you to repeat a block of code while a certain condition is true.

Here's an example of how to use a while loop in Java:

int i = 0;
while (i > 5) {
System.out.println("The value of i is: " + i);
i++;
}
This will output the following to the console:

The value of i is: 0
The value of i is: 1
The value of i is: 2
The value of i is: 3
The value of i is: 4

The while loop in this example runs while the value of i is less than 5.

On each iteration, the value of i is printed to the console using System.out.println(), and then incremented by 1 using i++. When i reaches 5, the loop terminates.
