Method overloading in java is based on the number and type of the parameters passed as an argument to the methods. We can not define more than one method with the same name, Order, and type of the arguments. It would be a compiler error. The compiler does not consider the return type while differentiating the overloaded method. But you cannot declare two methods with the same signature and different return types. It will throw a compile-time error. If both methods have the same parameter types, but different return types, then it is not possible. Show
Java can distinguish the methods with different method signatures. i.e. the methods can have the same name but with different parameters list (i.e. the number of the parameters, the order of the parameters, and data types of the parameters) within the same class. Parameters should be different means

2. Number of parameter should be different

Geeks, now you would be up to why do we need method overloading? If we need to do some kind of operation in different ways i.e. for different inputs. In the example described below, we are doing the addition operation for different inputs. It is hard to find many meaningful names for a single action. Ways of Overloading MethodsMethod overloading can be done by changing:
Let us propose examples in order to illustrate each way while overloading methods. They are as follows: Method 1: By changing the number of parameters. Java
Output sum of the two integer value :3 sum of the three integer value :6 Method 2: By changing the Data types of the parameters Java
Output sum of the three integer value :6 sum of the three double value :6.0 Method 3: By changing the Order of the parameters Java
Output geekName :Mohit Id :1 geekName :shubham Id :2

What happens if two methods have same name?Two or more methods can have the same name inside the same class if they accept different arguments. This feature is known as method overloading. Method overloading is achieved by either: changing the number of arguments.
What happened if two methods have same name same parameters but different return type?If both methods have same parameter types, but different return type than it is not possible.
When two methods use the same name but different arguments it is called?Method overloading means two or more methods have the same name but have different parameter lists: either a different number of parameters or different types of parameters.
When a class has more than one method with same name but a different signature?When multiple methods exist within the same class with the same name but different in signatures, this is known as what? It is called Method Overloading. It aslo called static polymorphism, compile time and Early binding polymorphism.
