Can anyone help me for this program?

import java.util.Stack;

public class Parentheses

{

// Return true if the parentheses in the specified string are properly

// matched; false otherwise. For example, [()]{}{[()()]()} is properly

// matched while [(]) is not.

public static boolean isValid(String s)

{

// TBD

}

// Test driver.

public static void main(String[] args)

{

System.out.println("Should print true: " +

isValid("[()]{}{[()()]()}"));

System.out.println("Should print false: " +

isValid("[(])"));

System.out.println("Should print true: " +

isValid("[hellp ( world ) !]"));
