In this section we are going to discuss the difference between method overloading and method overriding. Firstly understand the definition of both terms in brief:<\/p>\n

Method overloading refers to a concept in which we have more than one method with a same name but differ in the number or types of parameters within a same class.<\/p>\n

Method overriding refers to a concept in which we redefine the method in child class with same name, same return type and same parameter list as its parent class method.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n

Method overloading is used\u00a0to increase the readability\u00a0of the program.<\/td>\nMethod overriding is used\u00a0to give the specific implementation\u00a0of the method that is already provided by its parent class.<\/td>\n<\/tr>\n
Method overloading is done\u00a0within class.<\/td>\nMethod overriding occurs\u00a0in two classes\u00a0that have IS-A relationship.<\/td>\n<\/tr>\n
In case of method overloading,\u00a0parameter must be different.<\/td>\nIn case of method overriding,\u00a0parameter must be same.<\/td>\n<\/tr>\n
Method overloading is the example of\u00a0compile time polymorphism.<\/td>\nMethod overriding is the example of\u00a0run time polymorphism.<\/td>\n<\/tr>\n
Method overloading cannot be performed by changing return type of the method only.\u00a0Return type can be same or different, but there must change in the parameter.<\/td>\nReturn type must be same or covariant\u00a0in method overriding.<\/td>\n<\/tr>\n
In method overloading, you can overload method in same class.<\/td>\nIn method overriding, you can only override method in child class.<\/td>\n<\/tr>\n
In method overloading, you\u00a0can overload static method in Java<\/a><\/td>\nIn method overriding, you\u00a0cannot override static method in Java<\/a>.<\/td>\n<\/tr>\n
In method overloading, private and final method can be overloaded in Java.<\/td>\nIn method overriding, private and final method cannot be overridden in Java.<\/td>\n<\/tr>\n
It may or may not need\u00a0<\/strong>inheritance\u00a0in Method Overloading.<\/td>\nIt always requires inheritance in Method Overriding.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"
