Question

What is a nested loop?

Answer 1

'A nested loop is one that uses another loop within itself. In the example below, the outer loop is executed three times. The inner loop is executed twice per outer loop iteration. Therefore, the pattern printed will be: 

          MM
          MM
          MM

Example: 

for (int i = 1; i <= 3; i++)
{for (int j = 1; j <= 2; j++)
System.out.print("M");
System.out.printIn();
}
