        // constructor (bare minimum)

        }

        //constructor
        public Individual(String last, String first, String BBA, String year, String gpa){
            lname = last;
            fname = first;
            qualification = BBA;
            year1 = year;

        //constructor
        public String getemail(){
            String value = "default";
            int amount;
            value = fname;
            String email = "default";
            email = value.charAt(0)+lname+"@memphis.edu";
            return email;
        }
        //constructor
        public String getUUID(){
            String id = "";
            int number;
            number = (int) ((Math.random()*100)+1.00);
            id = number +fname.substring(0,1) + lname.substring(0, 1);
        }
}

当我编译它时，由于分号，它给我一个语法错误无法弄清楚为什么，任何帮助将不胜感激！

Answer 1

您的getUUID()方法定义为返回String，但您永远不会return。您可能想要添加return id;。此外，您通过不充当构造函数的方法有几个//constructor注释。

Answer 2

整理缩进，为变量赋予有意义的名称。他们会在现在和将来帮助你做得更好。

getEmail和getUUID也不是构造函数，需要返回值。构造函数必须与类名相同。

为什么我在最后一行有语法错误？
