Java之栈结构

import java.util.ArrayList;
import java.util.List;

public class StackNow {
    private List stack;
    public StackNow(){
        this.stack=new ArrayList();
    }
    //入栈
    public void plush(Object object){
        stack.add(object);
    }
    //弹栈
    public Object pop(){
        Object o = stack.get(stack.size() - 1);
        stack.remove(stack.size() - 1);
        return o;
    }

    public static void main(String[] args) {
        StackNow stackNow=new StackNow();
        String a="12321";
        Integer b=123;
        Double c=213.2;
        String d="你好啊";
        stackNow.plush(a);
        stackNow.plush(b);
        stackNow.plush(c);
        stackNow.plush(d);
        Object pop = stackNow.pop();
        System.out.println(pop);//你好啊

        Object pop1 = stackNow.pop();
        System.out.println(pop1);//213.2
    }
