Answer 1

If a class has a multiple functions by same name but different parameters is called method overloading.
Method overriding If subclass (child class) has the same method as declared in the parent class, it is known as method overriding in Java.

Answer 3

When we have multiple methods with the same name but different functionality then it's called method overloading.
For example, System.out.println() is overloaded as we have 5 or 6 println() method each accepting a different type of parameter ( e.g. which takes String, int, double or even char in output ). All of those methods are collectively referred as an overloaded method in Java.

Method overriding is one of the magic of object oriented programming where the method is chose based upon an object at runtime. In order for method overriding, we need Inheritance and Polymorphism, as we need a method with the same signature in both superclass and subclass.

In method overloading, Only name of two overloaded methods are same but method signature must be different while in method overriding, method signature must be same.

Method overriding represent true polymorphic behaviour, where only name needs to be same underlying method logic can be different.

Answer 4

The most important one is that method overloading is resolved at compile time and method overriding is resolved at runtime.

The compiler only used the class information for method overloading, but it needs to know object to resolved overridden method calls.

Answer 5

Overloading occurs when two or more methods in one class have the same method name but different parameters. 

Overriding means having two methods with the same method name and parameters. One of the methods is in the parent class and the other is in the child class.

Answer 7

If a class has a multiple functions by same name but different parameters (arguments) is called method overloading in java.

And if child class or subclass has the same method as declared in the parent class is call method Overriding in java.
