For loop in Java. While Loop in Java. For Each Loop in Java. Java Loop tutorial for beginners.

A For Loop is used to repeat a specific block of code a known number of times. For example, if you want to send an email to each of your customers, you would repeat the code N times where N is the number of all your customers.

A While loop is similar to the For loop because you also repeat a specific block of code a know number of times but the syntax is a bit different.
There is a basic While loop and a Do-While loop and I explain both of them.

The third loop in Java is a For Each loop. It can be used to iterate over arrays and collections. It is similar to the "normal" for loop but the syntax is clearer and easier to understand.
