Public class Student {
//class variables encapsulated 
private String id; 
private String name; 

//void structure 
Public Student () {
super(); 
} 
//structure with parameter 
Public Student (String studentNo, String name) {
super(); 
This. Id=studentNo; 
this.name=name; 

} 
//class variables set, the get method 
Public String getName () {
return name; 
} 
Public void elegantly-named setName (String name) {
this.name=name; 
} 
Public String getStudentNo () {
return id; 
} 
Public void setStudentNo (String studentNo) {
This. Id=studentNo; 
} 

//use the toString method for the class variable output 
@ Override 
Public String toString () {
Return "{\ " id ":" + id + ", \ "name " : "+ name +"} "; 
} 

}
