is generics allowed in method types

[Maharshi Soni]

interface Foo{
int getNumber();
}
class Bar implements Foo{
public int getNumber(){
return 1;
}
}
class Baz implements Foo{
public int getNumber(){
return 1;
}
}
public class Test2 {
   static boolean compare(T t , U you){//line 1
     return t.getNumber()==you.getNumber();
   }
    public static void main(String[] args) {
       boolean b =compare(new Bar(),new Baz());
       System.out.println(b);
    }
    
}

Answer mentioned as true

Welcome to CodeRanch!

Yes, you're allowed to use generic type parameters in methods. But to use them, you must first declare them.

There are two ways of declaring type parameters:

In a class header:

class Test2<T extends Foo, U extends Foo> {

In a method header:

static <T extends Foo, U extends Foo> boolean compare(T first, U second) {

Note that generic type parameters declared in class headers can not be used in static methods. To use them, make the method non-static, or move the generic type parameters to the method signature.

In your particular case, you don't need generics at all. Just declare your method to accept arguments of type Foo.
