// single inheritance
class Applicant
{
String applicantId;
String applicantName;
String applicantAdress="12.parker Street";
String applicantPosition=" Manager ";
public void displayDetails()
{
System.out.println("APPLICANT ID:"+applicantId);
System.out.println("APPLICANT NAME:"+applicantName);
System.out.println("APPLICANT ADDRESS:"+applicantAdress);
System.out.println("APPLICANT POSITION:"+applicantPosition);
}
}
class Candidate extends Applicant
{
String interviewDate;
boolean candidateStatus=false;
public Candidate(String ID,String Name,String intDate)
{
applicantId=ID;
applicantName=Name;
interviewDate=intDate;
}
public void displayDetails1()
{
displayDetails();
System.out.println("DATE FOR INTERVIEW:"+interviewDate);
System.out.println("STATUS OF CANDIDATE:"+candidateStatus);
}
public static void main(String[] args)
{
Candidate c=new Candidate(args[0],args[1],args[2]);
c.displayDetails();
}
}

the error is :
Exception in thread "main" java.lang.arrayIndexOutOfBoundException:0
at Candidate.main(Candidate.java:34)

i ran it and did not get any error.
Did you give arguments when you run it ?

[Ammar Salem]

No i did not give any arguments OPPs!!! Sorry
thank you .

ergo, the code needs fixing:

public static void main(String[] args)
{
if (args.length == 3) {
Candidate c=new Candidate(args[0],args[1],args[2]);
c.displayDetails();
} else {
System.err.println("Expecting 3 arguments!");
}
}
