石头，剪刀，布 循环版（改进）

问题及代码：

package first;import java.util.Scanner;public class text {public static void main(String[] args) {System.out.println("scissor for 0 , rock for 1 , paper for 2");String n[] = { "scissor", "rock", "paper" };Scanner get = new Scanner(System.in);Scanner getx = new Scanner(System.in);int a, b;int i = 0, j = 0;while (true) {int cp = (int) (Math.random() * 3);a = get.nextInt();while (!(a == 0 || a == 1 || a == 2)) {System.out.println("输入非法，请重新输入！");a = get.nextInt();}if (a - cp == 1)++i;else if (cp == a);else if (cp == 2 && a == 0)++i;else++j;System.out.println("you is " + n[a] + " the cp is " + n[cp]);System.out.println("");b = i;if ((i > 1) || (j > 1)) {if (b > 1)System.out.println("you win!");elseSystem.out.println("the cp win!");System.out.println("");System.out.println("是否继续游戏？ 1 继续  0 终止");if (getx.nextInt() == 0)break;else {System.out.println("scissor for 0 , rock for 1 , paper for 2");i = 0;j = 0;}}}}}
