Can we have two methods in a class with the same name?

Two or more methods can have the same name inside the same class if they accept different arguments. This feature is known as method overloading. Method overloading is achieved by either: changing the number of arguments.

Is it possible to have two methods within the same class that have the same name and parameter lists but which have different return types?

if the number of parameters and their types is same but order is different then it is possible since it results in method overloading. It means if the method signature is same which includes method name with number of parameters and their types and the order they are defined.

Can two methods of a class have the same name and the same signature?

You cannot declare more than one method with the same name and the same number and type of arguments, because the compiler cannot tell them apart. The compiler does not consider return type when differentiating methods, so you cannot declare two methods with the same signature even if they have a different return type.

Is it possible to have more than one methods having the same name inside a class body?

Method overloading. In a class, there can be several methods with the same name. However they must have a different signature. The signature of a method is comprised of its name, its parameter types and the order of its parameters.

When 2 or more methods in the same class have the same name it is called method?

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

Java Programming Tutorial - 14 - Using Multiple Classes

When multiple methods exist within the same class?

When multiple methods exist within the same class with the same name but different in signatures, this is known as what? It is called Method Overloading.

When the same name is used for two or more methods in the same class How does Java tell them apart?

1 Answer. Show activity on this post. Java can tell apart different methods by their method signature.

Can two different classes contain methods with the same name Java?

For convenience, Java allows you to write more than one method in the same class definition with the same name. For example, you can have two methods in ShoppingCart class named computeCost. Having two or more methods named the same in the same class is called overloading.

Can we overload methods on return type?

No, you cannot overload a method based on different return type but same argument type and number in java.

Can we override static method?

Overloading is the mechanism of binding the method call with the method body dynamically based on the parameters passed to the method call. Static methods are bonded at compile time using static binding. Therefore, we cannot override static methods in Java.

Can two interface have same method?

Yes, a class can implement two two interfaces with the same method signature but that method should be implemented only once in the class.

Can two methods have the same signature in Java?

The compiler does not consider the return type while differentiating the overloaded method. But you cannot declare two methods with the same signature and different return types. It will throw a compile-time error.

Can we overload main method?

Yes, we can overload the main method in Java, but When we execute the class JVM starts execution with public static void main(String[] args) method.

Is it permissible to define two methods that have the same name but different parameter types?

Method overloading in Java occurs when two or more methods in the same class have the exact same name but different parameters. It is allowed to have identical method names, as long as the parameter types are sufficintly different.

Can we execute a Java program without a main () method?

Yes, we can execute a java program without a main method by using a static block. Static block in Java is a group of statements that gets executed only once when the class is loaded into the memory by Java ClassLoader, It is also known as a static initialization block.

Can we change return type in overriding?

Yes. It is possible for overridden methods to have different return type . But the limitations are that the overridden method must have a return type that is more specific type of the return type of the actual method.

What is difference between overriding and overloading?

What is Overloading and Overriding? When two or more methods in the same class have the same name but different parameters, it's called Overloading. When the method signature (name and parameters) are the same in the superclass and the child class, it's called Overriding.

Can constructor be overloaded?

Constructors can be overloaded in a similar way as function overloading. Overloaded constructors have the same name (name of the class) but the different number of arguments. Depending upon the number and type of arguments passed, the corresponding constructor is called.

How many methods can a class have?

The number of methods that may be declared by a class or interface is limited to 65535 by the size of the methods_count item of the ClassFile structure (§4.1). Note that the value of the methods_count item of the ClassFile structure does not include methods that are inherited from superclasses or superinterfaces.

When two methods in the same class have the same name but different arguments This is an example of?

Overloading happens when you have two methods with the same name but different signatures (or arguments). In a class we can implement two or more methods with the same name.

Can we call same method in Java?

Yes you can. It is called recursion .

Can we overload method in child class?

Overloading can happen in same class as well as parent-child class relationship whereas overriding happens only in an inheritance relationship.

When a method in a subclass has the same name?

Explanation: When a method in a subclass has the same name and type signatures as a method in the superclass, then the method in the subclass overrides the method in the superclass.

Can overloaded methods be overridden?

So can you override an overloaded function? Yes, since the overloaded method is a completely different method in the eyes of the compiler.

Can we declare main method as private?

Yes, we can declare the main method as private in Java. It compiles successfully without any errors but at the runtime, it says that the main method is not public.
