java - The type Stack is not generic; it cannot be parameterized with arguments <Character> -

i trying write simple program use stacks.it giving me error

the type stack not generic; cannot parameterized arguments

import java.util.*;      public class stack {             public static void main(string[] args)             {                 stack<character> stack = new stack<> ();                 s.push("hello");                 system.out.println(s);              }          } 

your class stack shadowing java.util.stack. rename class, or use qualified class name like

java.util.stack<character> stack = new java.util.stack<> ();
