how to loop 2 for loops in java code example

Example 1: for loop java

// Starting on 0:
for(int i = 0; i < 5; i++) {
  System.out.println(i + 1);
}

// Starting on 1:
for(int i = 1; i <= 5; i++) {
  System.out.println(i);
}


// Both for loops will iterate 5 times,
// printing the numbers 1 - 5.

Example 2: nested for loop in java

// outer loop
for (int i = 1; i <= 5; ++i) {
  // codes

  // inner loop
  for(int j = 1; j <=2; ++j) {
    // codes
  }
..
