Q1: 兄弟帮忙看看我的java代码 老提示找不到符号
我只是在你的程序上加了打印，是可以看到程序本身并没有错误的。。。
import java.util.*;
public class Czyx
{
public static void main(String[] args)
{
System.out.println("请输入一个1-100之间的整数,谢谢!");
int a,k,j;
a=sr();
System.out.println("a="+a);
j=(int)(Math.random()*100);
System.out.println("j="+j);
for(k=1;k=10;k++)
{
if(aj)
{
System.out.println("good.aj 了!~~");
a=sr();
continue;
}
if(aj)
{
System.out.println("太大了!这是第"+k+"次输入!");
a=sr();
continue;
}
else
System.out.println("Good!你获得了"+(100-(k-1)*10)+"分!");
break;
}
}
public static int sr()
{
int b;
Scanner a=new Scanner(System.in);

while(b0||b100)
