if (true);

if (true);
else if (false);

for (int x = 0; x<5; x++)
      System.out.println(x);

for (int x = 0; x<5; x++)
                  
      System.out.println(x);

NOTE: the space between the two lines does not cause an error.

for (int x = 0; x<5; x++)
       // comments here
      System.out.println(x);

for (int x = 0; x<5; x++)
       for (int y = 0; y<5; y++)
             for (int z = 0; z<5; z++)
                  System.out.println(x);
