//下面为编译时爆出的错误
Scannertest.java :11: Error: symbol not found
max1 = (numl> num2)? numl: num2;
//下面为我的代码

public class ScannerTest{
public static void main(string[] args)｛
//交换num1与num2
int num1= 2, num2= 3, num3= 4;
int temp;
temp= num1;
num1= num2；
num2= temp;
//3个数选最大
int max;
max1= (num1> num2)? num1: num2;
max= (max1 >num3)? max1: num3;
System. out. printLn (max）；
}
}

num1= num2；
System. out. printLn (max）；
后面的分号是全角字符，改成半角的。

这个是我在手机上写的有些错误，但我编译时是在电脑上的itell idea上面，想截图给你但这个图片怎么发？

问题是找不到字符temp 与xlmax
public class ScannerTest{
    public static void main(String[] args) {

        int num1 = 2;
        int num2 = 3;
        int num3 = 4;
        int temp;
        temp= num1;
        num1= num2
        num2= num3;                                                                                                                                                                                                                                                                                                                                             

        int max= 1;
        max1=(num1>num2)? num1:num2;
        max= (max1>num3)? max1:num3;
        System.out.println(max);

        double lmax=(num1>num2)? num1:((num1==num2)? num1:num2);

        int lxmax;
        if (num1 >= num2 && num1 >= num3) {
            xlmax = num1;
        } else if (num2 >= num1 && num2 >= num3) {
            xlmax = num2;
        } else {
            xlmax = num3;
        }
    }
}

num1= num2后面缺分号
max1没有定义
lxmax和后面的xlmax拼写不一致

这3处修改后：

我像你这样写了，可是xlmax=num1 xlmax=num2 xlmax=num3还是显示找不到符号

谢谢😜
