返回readStatus；}

您在

readStatus（）

函数中提到了

字符串返回类型

，但您没有放入return语句。我认为这样可以

public static String readStatus() {
 Scanner scan = new Scanner(System.in);
 String status = "";
 do {
 System.out.print("Enter the status of the taxpayer: ");
 status = scan.nextLine();
 if (status != 'single' && status != 'married' && status != 'legally separated' && status !='widow/er'); 
 
 System.out.println("You have to type single. married, legally separated or widow/er");
 } while (status == 'single' && status == 'married' && status == 'legally separated' && status =='widow/er');

但是问题是它一直显示“无效字符常量”你好，你能不能也给我们看一下错误消息。你能不能正确缩进你的代码，这样我们就可以不费力地阅读它？您的IDE可以为您和我们做到这一点。非常感谢。

public static String readStatus() {
 Scanner scan = new Scanner(System.in);
 String status = "";
 do {
 System.out.print("Enter the status of the taxpayer: ");
 status = scan.nextLine();
 if (status != 'single' && status != 'married' && status != 'legally separated' && status !='widow/er'); 
 
 System.out.println("You have to type single. married, legally separated or widow/er");
 } while (status == 'single' && status == 'married' && status == 'legally separated' && status =='widow/er');

        public static String readStatus() {
         Scanner scan = new Scanner(System.in);
         String status = "";
         do {
         System.out.print("Enter the status of the taxpayer: ");
         status = scan.nextLine();
         if (status != 'single' | status != 'married' | status != 'legally separated' | status !='widow/er'){
         System.out.println("You have to type single. married, legally separated or widow/er");
return;
    }
return status;
         } while (status == 'single' | status == 'married' | status == 'legally separated' | status =='widow/er');
