How Is the Term Parameter Used in Java

How Is the Term Parameter Used in Java Parameters are the variables that are listed as part of a method declaration. Each parameter must have a unique name and a defined data type. Parameter Example Within a method to compute a change to a Circle objects position, the method changeCircle accepts three parameters: a name of a Circle object, an integer representing a change to the X-axis of the object and an integer representing a change to the Y axis of the object. public void changeCircle(Circle c1, int chgX, int chgY) { c1.setX(circle.getX() chgX); c1.setY(circle.getY() chgY); } When the method is called using example values (e.g., changeCircle(Circ1, 20, 25)), the program will move the Circ1 object up 20 units and right 25 units. About Parameters A parameter may be of any declared data type either primitives like integers, or reference objects including arrays. If a parameter may become an array of an indeterminant number of data points, create a  Ã¢â‚¬â€¹vararg  by following the parameter type with three periods (an ellipsis) and then specifying the parameter name.​
