Inheritance in Java, how to properly inherit a method?

Question

Java

Good afternoon.
There is an initial class which contains some methods.
Something like:

public List<datastrucutre> calculate(Math math){
//somecode
return List<datastrucure>;
}

I want to create a derived class that has the same methods but is considered a little different.
I create a class and say with the help of extend from whom I inherit
And write the following code.

@Override
public List<datastrucutreEXTENDSMATH> calculate(Math math){
//somecode, changed
return List<datastrucureEXTENDMATH>;

however, the compiler throws an error
Error:(34, 40) java: giveBy() in cannot override giveBy(r) in
return type java.util.List is not compatible with java.util.List<>
Error:(33, 5) java : method does not override or implement a method from a supertype
What am I doing wrong?

Answer 1

The inherited and the successor must have the same prototype, i.e. the same name, input parameters, and return data type.
You have different types returned.
Way out in the forehead - to return the base type, for example.
