Java Operators

Operators

• An operator (like in math) is used to modify a stored value
  • E.g. consider two integers stored in memory, that we want to add. We would first declare the integers, and then use the + operator to perform addition

    		int x = 5;
    		int y = 10;
    		int sum = 0;
    		sum = x + y;

    • The addition of x and y is stored in the variable sum
  • Java has many operators. The most important ones we will explore are:
    • Addition                        +
    • Subtraction                   -
    • Multiplication                 *
    • Division                         /
    • Assignment                   =
    • Function Call                  .
