Detailed explanation-1: -Although every while loop has the same general form, while loops can be used to serve a variety of different purposes. A common form of loop is the counting loop, in which the loop repeats a fixed number of times.
Detailed explanation-2: -Although we can use a while-structure to code a counting loop, Java’s for statement is ideally suited for this purpose.
Detailed explanation-3: -The loop variable is created when the for statement runs, so you do not need to create the variable before then. Each iteration assigns the the loop variable to the next element in the sequence, and then executes the statements in the body. The statement finishes when the last element in the sequence is reached.
Detailed explanation-4: -A “For” Loop is used to repeat a specific block of code a known number of times. For example, if we want to check the grade of every student in the class, we loop from 1 to that number.
