public class Student1 {
    static String words = "全局变量";
    public void getStu(){
        String words = "局部变量";
        System.out.println("words 变量现在是："+words);
        System.out.println("访问全局变量："+this.words);
    }
    public static void main(String[]args){
        Student1 student = new Student();
        student.getStu();
    }

}

出现的错误是
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
    Student cannot be resolved to a type

    at Student1.main(Student1.java:10)

有人吗

Student1 student = new Student() //  应该是 new Student1()  复制到编辑器一看就知道了

public class Student1 {
    static String words = "全局变量";

    public static void main(String[] args) {
        Student1 student = new Student1();
        student.getStu();
    }

    public void getStu() {
        String words = "局部变量";
        System.out.println("words 变量现在是：" + words);
        System.out.println("访问全局变量：" + this.words);
    }
}

words 变量现在是：局部变量
访问全局变量：全局变量
