Java Stack类顾名思义,实现堆栈。具体方法如下:
import java.util.Stack; public class StackTest { public static void main(String[] args) { Stack<String> stack = new Stack<String>(); System.out.println("now the stack is " + isEmpty(stack)); stack.push("1"); stack.push("2"); stack.push("3"); stack.push("4"); stack.push("5"); System.out.println("now the stack is " + isEmpty(stack)); System.out.println(stack.peek()); System.out.println(stack.pop()); System.out.println(stack.pop()); System.out.println(stack.search("2")); } public static String isEmpty(Stack<String> stack) { return stack.empty() ? "empty" : "not empty"; } }
