A good answer might be:

1/2 + 1/2  = 0

It looks as though this is a mistake, but no: each 1/2 calls for integer division, resulting in an integer 0. The two zeros are added to get the final answer, zero.

Copy-and-Paste Program

If you really want to add one half to one half you should write 1.0/2.0 + 1.0/2.0 because now the decimal points make each number a double. Here is a Java application that illustrates these points: 

class integerDivision
{
  public static void main ( String[] args )
  {
    System.out.println("The result is: " + (1/2 + 1/2) );
  }
}

Remember that you can run this program by copying it to Notepad, saving to a file integerDivision.java, compiling and running it. See a previous chapter for details on doing this. It would be nice if you made a few changes to the program in Notepad then ran the program again the see the effect.

Notice the parentheses around   (1/2 + 1/2). These are necessary so the arithmetic is done first, then the result is converted to characters and appended to the string.
