Parameters and Return Types in Methods

Parameters

The parameters are the inputs that a Java method takes. These are given as an ordered list in parentheses next to the name of the method. We can have any number of parameters.

• If a method does not have any parameters, the parentheses are left empty.

  public static void function()
  {
    // implementation here
  }
  

• Otherwise, for each parameter, we give the type and the name, separated by a comma, in the method’s signature.
