Java Nested Loops

Java Nested Loops:

Java Nested loop means a loop statement inside another loop statement.  For example, a while loop can be nested inside another while loop or a for loop can be nested inside another for loop. In fact, the nested loops do not need to be the same loop type, that is, a for loop can be nested inside a while loop, and a while loop can be nested inside a for loop. Nested loops may be useful if we are performing multiple operations, each of which has its own count or sentinel value.
