Multilevel Inheritance
Conside the following code for multilevel inheritance example :
Example
class student {
int rollno;
String name;
student(int r, String n) {
rollno = r;
name = n;
}
void dispdatas() {
System.out.println("Rollno = " + rollno);
System.out.println("Name = " + name);
}
}
class marks extends student {
int total;
marks(int r, String n, int t) {
super(r, n); // call super class (student) constructor
total = t;
}
void dispdatam() {
dispdatas(); // call dispdatap of student class
System.out.println("Total = " + total);
}
}
class percentage extends marks {
int per;
percentage(int r, String n, int t, int p) {
super(r, n, t); // call super class(marks) constructor
per = p;
}
void dispdatap() {
dispdatam(); // call dispdatap of marks class
System.out.println("Percentage = " + per);
}
}
public class MultipleInheritanceJava {
public static void main(String args[]) {
percentage stu = new percentage(1912, "SAM", 350, 50); // call
// constructor
// percentage
stu.dispdatap(); // call dispdatap of percentage class
}
}
Output
Rollno = 1912 Name = SAM Total = 350 Percentage = 50
