Answer 1

public class Student{
public static void main(String[] arge){
Student ss=new Student("印度阿三"，‘男’，56);

ss.setStudent();
}

private String name;
private char sex;
private int age;

public Student(){}
public Student(String name;char sex;int age;){
this.name=name'

this.sex=sex;

this.age=age;

}

public void setStudent(name,sex,age){

System.out.println(name+sex+age)

}
}

Answer 2

public class Student {

private int id;
private String name;

public Student(){}

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

public void setId(int id){
this.id=id;
}
public void setName(String name){
this.name=name;
}

public String toString(){
return name+","+id;
}

public static void main(String[] args) {
Student student=new Student();
student.setId(1234);
student.setName("tom");
System.out.println(student.toString());

}

}
