Java puzzle 29: Loops and branching statements

Level: Normal

What is the output of the following code?

public class MyClass
{
  static int x;
  
  public static void main(String[] args)
  {
    for(int i = 0; i < 5; i++)
    {
      if(i == 2)
      {
        break;
      }
      else
      {
        return;
      }
      x += 3;
    }
    System.out.println(x);
  }
}

Answer explanation

The statement x += 3; is unreachable. When the value of the variable i is equal to 2 the statement break; terminates the loop.
For other values of i the statement return; terminates the execution of the code.
Therefore the code doesn’t compile.
