Function overloading

Function overloading happens when a class has multiple methods with the same name. If we define a getData method twice in our class, we can say that the getData function is overloaded, as shown in the following code:

package coreJava;//function overloadingpublic class childlevel extends childClassDemo {    public void getData(int a)    {         }    public void getData(String a)    {         }    public static void main(String[] args) {        childlevel cl=new childlevel();        cl.getData(2);        cl.getData("hello")    }}

There are a few rules that we need to remember while using multiple instances of a function with the same name. The first rule is that the number of arguments present in the function-overloaded method should be different, and the second is that ...
