- What is the difference between method overloading and overriding . . .
Method overriding is when a child class redefines the same method as a parent class, with the same parameters For example, the standard Java class java util LinkedHashSet extends java util HashSet The method add() is overridden in LinkedHashSet

Overloading and overriding are complementary things, overloading means the same method name but different parameters, and overriding means the same method name in a subclass with the same parameters So its not possible for overloading and overriding to happen at the same time because overloading implies different parameters Examples:
- terminology - Overwrite or override - Stack Overflow
We talk about method overriding if the method defined in the subclass specialises the original implementation of the method to a special case, but in an incremental way, by making use of a super call The effect of the super call is to execute the behaviour as defined by the original method, but in addition to that the method in the subclass
- Polymorphism vs Overriding vs Overloading - Stack Overflow
Method overriding means we use the method names in the different classes,that means parent class method is used in the child class In Java to achieve polymorphism a super class reference variable can hold the sub class object
- Java overloading vs overriding - Stack Overflow
As Rob identified, I believe you mean overriding, and you have that correct Note with overriding, you cannot change the return type As of Java 5, you can return a derived type of what the base class method returned Before Java 5, it must be the identical type That is, you cannot do the below until Java 5 and later:
- Overriding == operator. How to compare to null? - Stack Overflow
Overriding Equals and GetHashCode doesn't necessarily override equality overloading operator Related
- overriding - How to override equals method in Java - Stack Overflow
According to Effective Java, Overriding the equals method seems simple, but there are many ways to get it wrong, and consequences can be dire The easiest way to avoid problems is not to override the equals method, in which case each instance of the class is equal only to itself
- Java overloading and overriding - Stack Overflow
Overloading Overriding Method Name Must be same Must be same Argument Types Must be same Must be different Return Type No restriction Must be same till 1 4V but after 1 4V co- variants were introduced private static final Can be overloaded Cannot be overridden Access Modifiers No restriction Cannot reduce the scope Throws keyword No restriction
