Description

The else keyword does not stand on it's own. It is an optional adjunct to the if keyword. The if/else combination basically executes a statement(or statements) if some condition is true. Otherwise, execute another statement(or statements).

Example 1

if (x<10) {
  System.out.println("Small number");
}
else {
  System.out.println("Big number");
}

Example 2

if (x == 1) {
  System.out.println("Spades");
}
else if(x == 2){
  System.out.println("Hearts");
}
else if(x == 3){
  System.out.println("Clubs");
}
else if(x == 4){
  System.out.println("Diamonds");
}
else{
  System.out.println("Invalid Suit");
}
