Java Class Example – Class in Java Example Program. You can find Source code for Class in Java.
class Student{
int rollNumber = 101;
String name = “eshusoft”;
void setStudent(int rno,String sname){
rollNumber=rno;
name=sname;
}
void display(){
System.out.println(“rollNumber =”+rollNumber);
System.out.println(“name =”+name);
}
}
public class ClassDemo {
public static void main(String[] args) {
Student obj = new Student();
System.out.println(“student object is created”);
System.out.println(“Roll Number:” + obj.rollNumber);
System.out.println(“Name:” + obj.name);
obj.display();
obj.setStudent(201, “eshusoft123”);
System.out.println(“student object is created”);
System.out.println(“Roll Number:” + obj.rollNumber);
obj.display();
}
}
Result:
student object is created
Roll Number:101
Name:eshusoft
rollNumber =101
name =eshusoft
