while loop is generally used when you don't know the number of times the loop should run. eg:- while(flag == true) { if(someCondition) flag = false; } for loop is used when you know the number of times the loop should run. eg:- for(int i = 0; i < array.length; i++) { // do something to each element of the array } this is how they are generally used, however they can interchange roles with a little work around.
