Question about java generic method declaration

The following type is not possible,

static <T> List<T> passed(List<T extends Taught>)

Because static cannot be generic. Remove the <T> infront of static and you are left with the same generic function declaration that you had previously. :laugh:

If you want to use generic return types (which you want to use!) then you need to create a generic class in Java. The class would determine what type of return values would be used. That would look something like the following,

class MyClass <T> {
    public MyClass() {
    }
    
    // Tricky part
    static <T extends Object> T passed (Class<T> paramType) {
       // Code here.
    }
}

// Use as
MyClass<string> obj = new MyClass<string>();

You can change the generic parameters to support the non-reference types (the primitive, int, double etc. types). But I would leave that upto you. :-)
