用java和cmd写一段小程序老是出现找不到这个符号

[SeventhMei]

public class cts {
public static void main(String[] args){
Scanner in = new Scanner(System.in);
System.out.println("请输入第一个数：");
double num1=in.nextDouble();
System.out.println("请输入第二个数：");
double num2=in.nextDouble();
System.out.println("请输入第三个数：");
double num3=in.nextDouble();
if(num1>num2&&num1>num3){
if(num2>num3){
System.out.println(num3+","+num2+","+num1);
}else{
System.out.println(num2+","+num3+","+num1);
}
}else if(num2>num3&&num2>num1){
if(num3>num1){
System.out.println(num1+","+num3+","+num2);
}else{
System.out.println(num3+","+num1+","+num2);
}
}else if(num3>num1&&num3>num2){
if(num1>num2){
System.out.println(num2+","+num1+","+num3);
}else{
System.out.println(num1+","+num2+","+num3);
}
}
}
}
都蒙圈了 找了好几遍都没找到第三行哪儿错了
