java stack list code example

Example 1: java stack

// construct with non-primative elements only!
Stack<String> stack = new Stack<String>();

// to add a value to the top of the stack:
stack.push("Hello");

// to return and remove a value from the top:
String top = stack.pop();

// to return a value without removing it:
String peek = stack.peek();

Example 2: java stack methods

import java.util.Stack<E>;
Stack<Integer> myStack = new Stack<Integer>();
myStack.push(1);
myStack.pop();
myStack.peek();
myStack.empty(); // True if stack is empty
