Java generics – insert internal type parameters

I'm new to Java I just want to pass comparable < string > into the method parameter of generic type < e extends comparable < E > > I believe that the meaning of < e extends comparable < E > > is any object that extends comparable Please tell me how to pass comparable < string > or any object that extends comparable < string > and there is another object

The compiler gave me the wrong inference that type comparison < string > is not a valid alternative to bounded parameters < e extends comparable < E > >

Code:

public class Compare<T> implements Comparable<T>{

    public int compareTo(T o) {

        return 0; // Not worried about logic

    }

}

class CompareTest{

    public <E extends Comparable<E>>void testGeneric(E e){

        System.out.println("Executed");
    }

    public static void main(String args[]){
        Compare<String> compare = new Compare<String>();

        CompareTest test = new Comparetest();
        test.testGeneric(compare);
        //The inferred type Compare<String> is not a valid substitute for the bounded
        //parameter <E extends Comparable<E>>
    }
}

Solution

E extends the comparable < E > representation: type E can be compared with other objects of the same type

However, your comparison type does not meet the criteria It cannot be compared with another Compare < T > can only compare itself to t, not < T > because it is declared as

public class Compare<T> implements Comparable<T>

It's hard to understand what you want to achieve with this comparison type
