Two methods can have the same signature when you override a method. A superclass calledrectangle might have a method called draw(). Then you make a subclass called squareand give it a method called draw() also. When you call the draw() method from square, it overrides the draw() method in rectangle. Note this is different than overloading, where you have two methods with the same name but different signatures, like draw() and draw(Color c).

Is it possible to have a method in the super class and sub class with same name but different signature?
Yes, it is perfectly possible. If two methods have a different signature, they can exist together irrespective of where they are present, either in the same class or in a super class, sub class situation. If two methods have the same signature and one exists in the super class and one in the sub class it is called method overriding.
The methods cannot have the same name in java true or false?
False. Methods in a class can have the same name as long as they have a different signature. You cannot duplicate method code inside a class but you can always have methods that have the same name but a different signature. Ex: Here I have created two methods in a class that have the same name "sum" but have a different argument types, and return types and hence perfectly allowable in a java class. Public class PolymorphismExample { public int sum(int a, int b){ return a + b; } public double sum (double a, double b){ return a + b; } }
Two methods cannot have the same name in Java A True B False?
Multiple methods with the same name is called method overloading. The way to do this is to have the different methods accept different parameters. Examples: Adding two values and returning the result. Let's use different methods for adding various numeric primitives. public static int add(int a, int b) { return a + b; } public static short add(short a, short b) { return a + b; } public static long add(long a, long b) { return a + b; } public static float add(float a, float b) { return a + b; } public static double add(double a, double b) { return a + b; }
What is function overloading in java?
Any function or method in Java that is coded by the programmer is called a user defined method in Java. The JAVA API (Application Programming Interface) has a set of predefined classes & methods that are for our usage. Whatever methods we create apart from these are termed as user defined methods. In java we not use the term functions. We call them "Methods"
What is the scope of method overloading and overriding?
Overloading happens when you have multiple methods in the current class that have the same name but different signature. The scope of method overloading is "Within the current class" Overriding happens when your current class extends another class (the parent class) and provides implementation for a method that is already available in the parent class. The scope of method overriding too is "Within the current class"

What is a signature in Java?
A signature is a term that we can use to identify a method. A method signature is something that helps us specifically identify a method. The components of a methods signature are: 1. Its access modifier 2. Return type 3. Parameters Ex: public void getName(int empnum){} public String getName(int empnum, int age){} The above two methods are of the same name but they have a different signature.
What key signature has two B flats?
No key signature has two of the same flat or sharp.
