Question

当我在eclipse中编译代码时，抛出错误

"Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
    String cannot be resolved to a type
    String cannot be resolved to a type
    System cannot be resolved
    String cannot be resolved to a type
    System cannot be resolved   "

但是我用大写的“ S”写了“ String”

下面是代码：

 public class student {
        int id;
        String name;
    }

class TestStudent1 {
    public static void main(String[] args) {
        student s = new student();
        s.name = "ram";
        s.id = 101;
        System.out.println(s.name);
        System.out.println(s.id);
    }
}

Answer 1

确保已保存文件并公开TestStudent1类，并将文件名更改为TestStudent1.java，如下所示，

class student {
    int id;
    String name;
}

public class TestStudent1 {
public static void main(String[] args) {
    student s = new student();
    s.name = "ram";
    s.id = 101;
    System.out.println(s.name);
    System.out.println(s.id);
}
}

这是输出：

ram 101
