Cannot Instantiate Type in generics
bounded-wildcard, generics, java, wildcard
Solution
While instantiating generics should be replaced with corresponding objects.
Ex:
Tree<Integer> num2 = new Tree<Integer>(2);
Problem
I have this class ``` public class Tree<T> { //List of branches for this tree private List<Tree<? super T>> branch = new ArrayList<Tree<? super T>>(); public Tree(T t){ this.t = t; } public void addBranch(Tree< ? super T> src){ branch.add(src); } public Tree<? extends T> getBranch(int branchNum){ return (Tree<? extends T>) branch.get(branchNum); } private T t; } ``` And I am trying to create a variable out of this class using this ``` public static void main(String[] args){ Tree<? super Number> num2 = new Tree<? super Number>(2); } ``` and it is giving me this error ``` Cannot instantiate the type Tree<? super Number> ```
