Assignment Operator

Assignment Operator

• The assignment operator allows us to assign
  the evaluation of the right-hand side of a
  statement to a variable on the left-hand side of
  a statement.
• Example sum number1 number 2
• Assume sum, number1, and number2 are int
• The right hand-side of the statement (number1
  number2) is evaluated first and assigned to the
  variable sum.
• sum will now hold the value calculated by number1
  number2

Assignment Operator (cont.)

• Another Example
• String input
• input JOptionPane.showInputDialog(Enter a
  number )
• The showInputDialog method will take the user
  input and return it as a String. This simply
  means that the right side of our statement
  becomes a String. This String is then assigned to
  the variable (input) on the left side.
• Now we may use this String in our program by
  referencing the variable input.
