5. INHERITANCE
Acquiring the properties from one
class to another class is called inheritance
(or)
Producing a new class from already
existing class is called inheritance
Reusability of code is main advantage of inheritance
In java Inheritance is achieved by
using extends keyword .
Properties with an access specifier
– private can’t be inherited.
Example:
class Parent{
String
Pname;
String
FamilyName;
}
class child extends Parent{
String childName;
int childAge;
void printMyName(){
System.out.println(“My name is”+
childName+ “ “+FamilyName);
}
Example 2:
package javatuts;
class person {
String name;
String addr;
int age;
void setdetails(String name,String addr,int age){
this.name=name;
this.addr=addr;
this.age=age;
}
void getdetails(){
System.out.println("name:"+name);
System.out.println("address:"+addr);
System.out.println("age:"+age);
}
}
package javatuts;
class employ extends person{
int id;
String companyName;
String companyAddress;
employ(int id,String name,String addr,int age,String companyName,String
companyAddress){
this.id=id;
setdetails(name,addr,age);
this.companyName=companyName;
this.companyAddress=companyAddress;
}
void getEdetails(){
System.out.println("employ
id"+id);
getdetails();
System.out.println("companyName:"+companyName);
System.out.println("company
address:"+companyAddress);
}
}
public class inherit {
public static void main(String[] args)
{
employ e1=new
employ(101,"raees","12-madhnagar",29,"softsolutions","20-hyu");
e1.getEdetails();
}}
Output:
employ id101
name:raees
address:12-madhnagar
age:29
companyName:softsolutions
company address:20-hyu
