If/Else

The if/else statement is used to execute code when a test condition is true.

if (x > 10) {
   System.out.println("x is greater than 10");
} else {
   System.out.println("x is less than 10");
}

Switch/Case and Breaks

The following code shows how to use a switch/case construct with a char. But any of the following primitive types are legal to test against: char, byte, short, or int.

switch (test) {
case 'A' :
      System.out.print("Found X");
      break; //Print 'X' if test = 'X'
   case 'B' :
      System.out.print("Found Y");
      break; //Print 'Y' if test = 'Y'
   default :
      //This code runs if test does not equal 'X' or 'Y'
      System.out.print("Found Z");
}

If neither break were there, and if test equaled 'X', the code would print XYZ. Java switch/case constructs ...
