Else If ex. if(a=6){System.out.println("It is six");} else(){System.out.println("It is not six");} Switch ex. switch(a){ case 1: System.out.println("it is one"); break; case 2: System.out.println("it is two"); break; default: System.out.println("it is not one or two"); break; } Basically a switch is a good way to check against a lot of possibilities.
