Can a class have 2 methods with same name?

Yes, we can define multiple methods in a class with the same name but with different types of parameters. Depending on the parameters, the appropriate method will be called.

Can two functions have the same name Java?

We cannot have two functions in one class with the same name and parameter list as the compilers cannot distinguish between these two functions , as such these functions are not allowed. Following are two example code in C++ and other in Java while compiling we get similar error message.

Can a class constructor be called more than once?

Constructor is called automatically when we create an object using new keyword. It is called only once for an object at the time of object creation and hence, we cannot invoke the constructor again for an object after it is created.

What is it called when two methods have the same name but different parameters?

Overloading occurs when two or more methods in one class have the same method name but different parameters. Overloading is known as compile-time polymorphism.

Can you have two methods with the same name in Java?

Two (or more) methods can have the same name but must have different parameters. For example, “int getHeight (int x)” and “int getHeight (String s)” can be the names of two methods in a class. This is called overloading of methods. 8. Java does not allow a method with the same signature in a subclass, as a method in the super class.

How are Java methods similar to C methods?

1) A Java method is comparable to a __ in c language. 2) All Java methods must have a return type. (TRUE / FALSE) 3) State TRUE or FALSE. A Java method can have the same name as the class name. 4) in Java, add a ___ to a constructor to convert it into a method. 5) Java method signature is a combination of ___.

Can two methods have the same name with different return types?

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. See: http://docs.oracle.com/javase/tutorial/java/javaOO/methods.html

Can a method have the same signature as another method?

Method Signature: Two methods or constructors, M and N, have the same signature if they have the same name, the same type parameters (if any) (§8.4.4), and, after adapting the formal parameter types of N to the the type parameters of M, the same formal parameter types.
