  1. FOR LOOP WALK THROUGH publicclassNestedFor{publicstaticvoid main(String [] args) { for (inti = 1; i <= 7; i++) {System.out.println();for (intj = 1; j <= i; j++) {System.out.print("*"); } } }}

  2. publicclassNestedFor// FIRST TIME THROUGH THE LOOP{publicstaticvoid main(String [] args) { for (inti = 1; i<= 7; i++) {System.out.println();for (intj = 1; j <= i; j++) {System.out.print("*"); } } }} i = 1 1 is less than or equal to 7 New line j = 1 1 is less than or equal to 1 Print * , increment, and loop 2 is NOT equal to 1 so fall out and return to outer for 01 02 * 03 04 05 06 07 08 09 10

  3. publicclassNestedFor// SECOND TIME THROUGH THE LOOP{publicstaticvoid main(String [] args) { for (inti = 1; i<= 7; i++) {System.out.println();for (intj = 1; j <= i; j++) {System.out.print("*"); } } }} 2 i = 2 2 is less than or equal to 7 New line j = 1 1 is less than or equal to 2 Print * , increment, and loop 2 is less than or equal to 2 Print * , increment, and loop 3 is NOT equal to 2, so fall out and return to outer for 01 02 * 03 ** 04 05 06 07 08 09 10

  4. publicclassNestedFor// THIRD TIME THROUGH THE LOOP{publicstaticvoid main(String [] args) { for (inti = 1; i<= 7; i++) {System.out.println();for (intj = 1; j <= i; j++) {System.out.print("*"); } } }} 3 i = 3 3 is less than or equal to 7 New line j = 1 1 is less than or equal to 3 Print * , increment, and loop 2 is less than or equal to 3 Print * , increment, and loop 3 is less than or equal to 3 Print * , increment, and loop 4 is NOT equal to 3, so fall out and return to outer for 01 02 * 03 ** 04 *** 05 06 07 08 09 10

  5. publicclassNestedFor// FOURTH TIME THROUGH THE LOOP{publicstaticvoid main(String [] args) { for (inti = 1; i<= 7; i++) {System.out.println();for (intj = 1; j <= i; j++) {System.out.print("*"); } } }} 4 i = 4 4 is less than or equal to 7 New line j = 1 1 is less than or equal to 4 Print * , increment, and loop 2 is less than or equal to 4 Print * , increment, and loop 3 is less than or equal to 4 Print * , increment, and loop 4 is less than or equal to 4 Print * , increment, and loop 5 is NOT equal to 4, so fall out and return to outer for 01 02 * 03 ** 04 *** 05 **** 06 07 08 09 10
