基础班学习心得（二）
这里有2个小游戏（第一个数猜拳游戏，第二个是猜数字游戏）这是一个猜拳游戏，一开始写的时候没有限定输入的字符，后期觉得得先判断下只能输入1，2，3这三个数。import
java.util.Random;
import
java.util.Scanner;
public class
DemoOne {
public static void
main(String[] args) {
Random random =
new
Random();
int
ran = random.nextInt(
3
) +
1
;
Scanner scanner =
new
Scanner(System.
in
);
while
(
true
) {
int
sca = scanner.nextInt();
if
(sca!=
1
&&sca!=
2
&&sca!=
3
){
System.
out
.println(
"输入有误"
);
continue
;
}
if
(sca ==
1
) {//石头
if
(ran ==
1
) {
System.
out
.println(
"电脑出"
+ ran);
System.
out
.println(
"石头对石头平局"
);
}
else if
(ran ==
2
) {
System.
out
.println(
"电脑出"
+ ran);
System.
out
.println(
"石头对剪刀，玩家胜利"
);
}
else if
(ran ==
3
) {
System.
out
.println(
"电脑出"
+ ran);
System.
out
.println(
"石头对布，电脑胜利"
);
}
}
if
(sca ==
2
) {
//剪刀
if
(ran ==
1
) {
System.
out
.println(
"电脑出"
+ ran);
System.
out
.println(
"剪刀对石头电脑胜利"
);
}
else if
(ran ==
2
) {
System.
out
.println(
"电脑出"
+ ran);
System.
out
.println(
"剪刀对剪刀，平局"
);
}
else if
(ran ==
3
) {
System.
out
.println(
"电脑出"
+ ran);
System.
out
.println(
"剪刀对布，玩家胜利"
);
}
}
if
(sca ==
3
) {//布
if
(ran ==
1
) {
System.
out
.println(
"电脑出"
+ ran);
System.
out
.println(
"布对石头玩家胜利"
);
}
else if
(ran ==
2
) {
System.
out
.println(
"电脑出"
+ ran);
System.
out
.println(
"布对剪刀，电脑胜利"
);
}
else if
(ran ==
3
) {
System.
out
.println(
"电脑出"
+ ran);
System.
out
.println(
"布对布，平局"
);
}
}
}
}
}
==================================================================================================
这个是猜数字游戏[1，100]，一开始猜的话是没有次数限制的，后期添加了次数限制。import
java.sql.SQLOutput;
import
java.util.Random;
import
java.util.Scanner;
public class
Demo04RandomGame {
public static void
main(String[] args) {
Random random =
new
Random();
int
ran = random.nextInt(
100
) +
1
;
//[1,100]数
Scanner scanner =
new
Scanner(System.
in
);
System.
out
.println(
"请输入1到100的数字"
);
int
scn =
0
;
while
(scn != ran) {
for
(
int
i =
0
; i <
3
; i++) {
scn = scanner.nextInt();
if
(scn > ran) {
System.
out
.println(
"偏大"
);
}
else if
(scn < ran) {
System.
out
.println(
"偏小"
);
}
else
{
System.
out
.println(
"猜对了"
);
break
;
}
}
System.
out
.println(
"游戏结束"
);
break
;
}
}
}
