IT技术字母


* toUpperCase 转换为大写字母 toLowerCase 转换为小写 。

编一个java应用程序,实现以下功能：1.程序随机在26个字母中选一个，让用import java.util.Scanner;
public class B {
public static void main(String[] args) {
String chars = "abcdefghijklmnopqrstuvwxyz";
char nletter = chars.charAt((int)(Math.random() * 26));
Scanner scanner = new Scanner(System.in);
char input;
String c;
do{
System.out.println("清猜字母(a-z)!");
c = scanner.next();
input=c.charAt(0);
if(inputnletter){
System.out.println("猜大了!");
}else if(inputnletter){
System.out.println("猜小了!");
}
}while(input != nletter);
System.out.println("猜对了" + nletter);
}
}
