JavaMethod Overloading
Method Overloading
With method overloading, multiple methods can have the same name with differentparameters:
Example
int myMethod(int x)float myMethod(float x)double myMethod(double x, double y)Consider the following example, which has two methods that add numbers of different type:
Example
static int plusMethodInt(int x, int y) { return x + y;}static double plusMethodDouble(double x, double y) { return x + y;}public static void main(String[] args) { int myNum1 = plusMethodInt(8, 5); double myNum2 = plusMethodDouble(4.3, 6.26); System.out.println("int: " + myNum1); System.out.println("double: " + myNum2);}Instead of defining two methods that should do the same thing, it is better to overload one.
In the example below, we overload theplusMethod method to work for bothint anddouble:
Example
static int plusMethod(int x, int y) { return x + y;}static double plusMethod(double x, double y) { return x + y;}public static void main(String[] args) { int myNum1 = plusMethod(8, 5); double myNum2 = plusMethod(4.3, 6.26); System.out.println("int: " + myNum1); System.out.println("double: " + myNum2);}Note: Multiple methods can have the same name as long as the number and/or type of parameters are different.
