//Line 1- Define a method timesTwo()

public static double timesTwo(double num)

{

//Line 2- Compute value

}

Methods:

  • The methods could be used to break a complex program into small pieces.
  • The “void” method simply executes a statements group and then terminates.
  • A value returning method would return a value to statement that has called it.
  • While calling a method, program would branch to that method.
  •  It would then execute statements in its body.
