![]() ![]() Return type can be same or different in method overloading. ![]() Method overriding is an example of run-type polymorphism.ĥ.Return type : Method overloading does not depend upon the return type of the method. Polymorphism type : Method overloading is an example of compile-type polymorphism. In method overriding, parameters must be same i.e method signatures (although parameters can be different for covariant return type).Ĥ. ![]() Parameters : In method overloading, parameters must be different. Method overriding involves two classes that have IS-A relationship (inheritance).In other words, parent class with child class is required for method overriding.ģ. Number of Classes Involved : Method overloading is performed with in class.So only one class is involved. Child class overrides the super class method.Ģ. Method overriding is used to provide the specific implementation of the method. Purpose : To increase the readability of the program, Method Overloading is used. Method Overriding must have the same method name and same parameters (method signature).Ħ Difference between Method Overloading and Method Overriding in javaġ. ![]() What is Method Overriding with Simple Example Hence, changing return type with two methods having same method name and parameters will result in compile time error. Note: Return type is not part of the method signature. Method Overloading must have the same method name and different parameters (method signature) i.e either you need to change number of parameters or type of parameters or order of parameters. What is Method Overloading with Simple Example Read Also : Difference between String, StringBuilder and StringBuffer Before answering the question, first we will understand what is method overloading and what is method overriding with simple examples. Difference between Overloading and Overriding is the most common interview question asked to the java developer. ![]()
