帮我看看，哪里有错

[liuleyiusst]

class Student {

private String name;
private int age;
private int number;

public Student(String name, int age, int number) {
this.name = name;
this.age = age;
this.number = number;
}

public void setStudent(String _name, int _age, int _number) {
name = _name;
age = _age;
number = _number;
}

public void display() {
System.out.println(name + " - " + age + " - " + number);
}
}

public class Stu {

public static void main(String[] args) {
Student student = new Student(liu, 20, 1);

student.display();
student.setStudent(chen, 20, 2);
student.display();

}
}
Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - cannot find symbol
symbol: variable liu
location: class stu.Stu
at stu.Stu.main(Stu.java:37)
Java Result: 1

你用记事本写的?
Student student = new Student(liu, 20, 1);
liu为字符串"liu"

[霜之哀伤]

Student student = new Student(liu, 20, 1);

错误信息说的很明白了啊
liu 没有定义过。
改成"liu"

[davis_rly]

public static void main(String[] args) {
Student student = new Student(liu, 20, 1); 错了 因为定义了String name，所以需要把liu需用“”才是一个字符串

[keeya0416]

public class Stu {

  public static void main(String[] args) {
  Student student = new Student(liu, 20, 1);//liu-->"liu"

  student.display();
  student.setStudent(chen, 20, 2); //这里也是 "chen"
  student.display();

  }
