how to do nested loops in java with a * 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: java nested for loop

for (int i = 0; i < 10; i++) {
	for (int j = 0; j < 10; j++) {
		System.out.println("*");
    }
  System.out.println("");
}
