java program to perform constructor overloading - SVRR TECH

Constructor overloading is a technique in Java in which a class can have any number of constructors that differ in parameter list.

Aim:

         To perform the constructor using method overloading concept in the java programming language      

Algorithm:

Step1:    Create a new text document and type the java program for implementing
constructor overloading concept.

Step2:    Create a base class named “over “ and initialize the employee no, name, job
and salary.

Step3:   Using “this” operator we can get the instance variable and using in various
methods.

Step4:   Print emp name, no, job, and salary using “System.out.println()” method.

Step5:   Create a main class named “ consover” and create object  x1, x2, x3 and x4. 

Step6:   Display  the value of x1, x2, x3, and x4.

Step7:   Save the program with “.java” extension.

Step8:   Compile it using “javac” command and  run the program using “java” 
    command. 

Program:

class over

{

int eno;

String ename,job;

double sal;

over()

{

eno=0;

ename=job=null;

sal=0.0;

}

over(int eno)

{

this.eno=eno;

this.ename="Ramesh";

this.job="Salesman";

this.sal=4500;

}

over(int eno,String ename)

{

this.eno=eno;

this.ename=ename;

this.job="Clerk";

this.sal=5600;

}

over(int eno,String ename,String job,double sal)

{

this.eno=eno;

this.ename=ename;

this.job=job;

this.sal=sal;

}

void Display()

{

System.out.println("Employee Number:"+eno);

System.out.println("Employee name:"+ename);

System.out.println("Job:"+job);

System.out.println("Salary:"+sal);

}

}

class consover

{

public static void main(String args[])

{

over x1=new over();

over x2=new over(101);

over x3=new over(102,"Ganesh");

over x4=new over(103,"Dinesh","programmer",6700);

x1.Display();

x2.Display();

x3.Display();

x4.Display();

}

}

OUTPUT:

Employee Number:0

Employee name:null

Job:null

Salary:0.0

Employee Number:101

Employee name:Ramesh

Job:Salesman

Salary:4500.0

Employee Number:102

Employee name:Ganesh

Job:Clerk

Salary:5600.0

Employee Number:103

Employee name:Dinesh

Job:programmer

Salary:6700.0
