double for loop in java code example

Example 1: java nested loop

// This nested for loop will print 5 rows of 20 asterisks each

for(int i = 0; i < 5; i++) {
  for(int j = 0; j < 20; j++) {
    System.out.print("*");
  }
  System.out.println();
}

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
  }
..
}
