___________________________________________________

public class MyList<AnyType>
{
private LinkedList<AnyType>list;
  
MyList()
{
list = new LinkedList<AnyType>();
}

public void myPush(AnyType x)
{
list.addFirst(x);
}
  
public AnyType myPop()
{
list.removeFirst();
return list.getFirst();
}

public void myInject(AnyType x)
{
list.addLast(x);
}

public static void main(String args[])
{
MyList<Integer>List = new MyList<Integer>();
List.myPush(3);
List.myInject(10);
List.myPush(5);
List.myPop();
}
}

Answer 1

/* USE toString() function to print contents of list */

import java.util.LinkedList;

public class MyList<AnyType>
{
private LinkedList<AnyType>list;

MyList()
{
list = new LinkedList<AnyType>();
}

public void myPush(AnyType x)
{
list.addFirst(x);
}

public AnyType myPop()
{
list.removeFirst();
return list.getFirst();
}

public void myInject(AnyType x)
{
list.addLast(x);
}

@Override
public String toString() { // to print list contains
return "MyList{" + "list=" + list + '}';
}

public static void main(String args[])
{
MyList<Integer>List = new MyList<Integer>();
List.myPush(3); // ADD 3
List.myInject(10); // ADD 10
List.myPush(5); // ADD 5
List.myPop(); // REMOVE 5
System.out.println(List.toString());// 3,10
}
}

/* OUTPUT */
