Java编程用两个栈实现队列代码分享

java;">import java.util.Stack;public class Solution {  Stack<Integer> stack1 = new Stack<Integer>();  Stack<Integer> stack2 = new Stack<Integer>();  public void push(int node) {    stack1.push(node);  }  public int pop() {    while(!stack1.isEmpty()){      stack2.push(stack1.pop());    }    int pop = stack2.pop();    while(!stack2.isEmpty()){      stack1.push(stack2.pop());    }    return pop;  }}
