Inheritance java Program using steps procedure

The java program to demonstrate the concept of inheritance program.inheritance program in java

procedure steps:

• step 1:Define a class by Name College and Declare two instance
•               Variable of type String.
• step 2: Define a Parameter Constructor to get Set
• 
  
• step 3: Declare a Method display College () To Show the value given.
• step 4: Define a Class Department which inrits.
• step 5: Declare Two Instance Variable of type string and define a Constructor.
• step 6: Using super keyword inside the Constructor Values to the Constructor of the Parent
•               Super Class.
• step 7: Define a Class By name College Demo.
• step 8: Define a main().
• step 9: Create object to "Department Class.
• step 10: Using one object of sub classs we accese the Method in Super to Display.

For Example Inheritance Program:

Class College
{
String collegeName,prinicipalName;
College (String cName,String pName)
{
collegeName=cName;
principalName=pName;
}
void dispalyCollege()
{
System.out.println("College Name:"+collegeName);
System.out.println("Principal Name:"+ principalname);
}
}
class Department extends College
{
String deptName,holdName;
Department(String cName,StringpName,String dName,String hName)
{
super(cName,pName);
deptName=dName;
hodName=hName;
}
void displayDepartment()
{
System.out.println("Department Name:"+deptName);
System.out.println("Hod Name:"=hodName);
}
}
class CollegeDemo
{
public static void main(String args[])
{
Department d;
d=new Department("your college name","Your principal name",Department Name",hod name");
d.displayCollege();
d.displayDepartment();
}
}


For example:  Enter the d=new department("your college name",
"Your principal name",Department Name",hod name");

Output:

C:\in\java>javac CollegeDemo.java
C:\in\java>java CollegeDemo

College Name:
Principal Name:
Department Name:

Hod Name:

RESULT:
    Thus the program Succesfully Exected.
