Java loops can execute the block of code as long as the specified condition is reached. The while loop loops through the block of code as long as the specified condition is true. A Java while loop is used to iterate the part of a program several times. If a number of iteration is not fixed, then it is recommended to use the while loop. If a number of iterations are fixed then use the  for loop.

Java While Loop

Java while loop evaluates an expression, which must return the boolean value. If the expression evaluates to a true boolean value, the while statement executes a statement(s) in a while block. The while statement continues testing the expression and executing its block until that expression evaluates to false.
