Answer 1

is the same as:No it isn't (in example have used 3 instead of 25 so output is shorter:
public class Test {
    public static void main(String[] args) {
        for (int x = 0; x < 3; x++) {
            System.out.println(x);
        System.out.println("****");
            int x = 0;
            while (x++ < 3) {
                System.out.println(x);
        System.out.println("****");
            int x = 0;
            do {
                System.out.println(x);
            } while (++x < 3);
Replace your suggested while loop with:
int x = 0;
while (x < 25) {
  //do something
  x++;
}To the OP: All this should be covered in just about any introductory Java book or tutorial. Have you read any? If so, what in particular are you having trouble with understanding? If not, then go and do so.
