I am new to JAVA generics below the return type is void but why are they giving the type .
public static <U> void addBox(U u,List<Box<U>> boxes){
Box<U> box = new Box<U>();
box.setT(u);
boxes.add(box);
}
The
<U>isn’t a return type. It is declaring thatUis a generic class that will be used in the method’s parameters and in the method body.You can read more about generic methods and their syntax here.
