weird output ?

[low1988]

The program cannot display the value which had assign to properly.The output is some weird texts.Why?

import java.util.ArrayList; 

class Employeee
{

private String name,department,position;
private int idNumber;

public Employeee()
{
name = null;
position = null;
department = null;
idNumber = 0;
}

public Employeee(String n,String p,String d,int i)
{
name = n;
position = p;
department = d;
idNumber = i;
}

public void setName(String n)
{
name = n;
}

public void setPosition(String p)
{
position = p;
}

public void setDepartment(String d)
{
department = d;
}

public void setidNumber(int i)
{
idNumber = i;
}


public String getPosition()
{
return position;
}

public String getDepartment()
{
return department;
}

public String getName()
{
return name;
}

public int getidNumber()
{
return idNumber;
}

 
}



public class EmployeeeTest
{

public static void main(String[] args)
{
Employeee emp1 = new Employeee("Dr.Nor Sabrina","Vice President","Accounting",47899);
Employeee emp2 = new Employeee("En Ahmad","Programmer","IT",39119);
Employeee emp3 = new Employeee("Prof M Izzudin","Manager","Consultation",66666);
Employeee emp4 = new Employeee("Dr N Izzati","CEO","Elect&Etronic",34521);
Employeee emp5 = new Employeee("Dr A Rahman","Manager","PR",12321);


ArrayList ar = new ArrayList();
ar.add(new Employeee("Dr.Nor Sabrina","Vice President","Accounting",47899));
ar.add(emp2);
ar.add(emp3);
ar.add(emp4);
ar.add(emp5);

 for(int i =0;i<ar.size();i++)
 {System.out.println(ar.get(i));}

 
 
 
}

}

are you getting something to the effect of, "@43df12"? That's because you're trying to print out an employee object. You have to get the employee's name, title, department, or id number and print that, or write a toString method that outputs all of the info.

The problem is my question request me to Print all the element of the listThe list of data which is consist of a table and create with the 5 objects which could be refer to

Employeee emp1 = new Employeee("Dr.Nor Sabrina","Vice President","Accounting",47899);
Employeee emp2 = new Employeee("En Ahmad","Programmer","IT",39119);
Employeee emp3 = new Employeee("Prof M Izzudin","Manager","Consultation",66666);
Employeee emp4 = new Employeee("Dr N Izzati","CEO","Elect&Etronic",34521);
Employeee emp5 = new Employeee("Dr A Rahman","Manager","PR",12321);

Then , i had populate the 5 object with the add() method to the ArrayList object "ar".After that i need to do is to print all the element in the list as requested by the question.

Anyway i had done some modification on the codes to have some feedback from u guys ,IS IT CORRECT OR NOT ?

import java.util.ArrayList; 

class Employeee
{

private String name,department,position;
private int idNumber;

public Employeee()
{
name = null;
position = null;
department = null;
idNumber = 0;
}

public Employeee(String n,String p,String d,int i)
{
name = n;
position = p;
department = d;
idNumber = i;
}

public void setName(String n)
{
name = n;
}

public void setPosition(String p)
{
position = p;
}

public void setDepartment(String d)
{
department = d;
}

public void setidNumber(int i)
{
idNumber = i;
}


public String getPosition()
{
return position;
}

public String getDepartment()
{
return department;
}

public String getName()
{
return name;
}

public int getidNumber()
{
return idNumber;
}

 
}



public class EmployeeeTest
{

public static void main(String[] args)
{
Employeee emp1 = new Employeee("Dr.Nor Sabrina","Vice President","Accounting",47899);
Employeee emp2 = new Employeee("En Ahmad","Programmer","IT",39119);
Employeee emp3 = new Employeee("Prof M Izzudin","Manager","Consultation",66666);
Employeee emp4 = new Employeee("Dr N Izzati","CEO","Elect&Etronic",34521);
Employeee emp5 = new Employeee("Dr A Rahman","Manager","PR",12321);


ArrayList ar = new ArrayList();
ar.add(emp1.getPosition()  + emp1.getDepartment() + emp1.getName() + emp1.getidNumber());
ar.add(emp2.getPosition() + emp2.getDepartment() + emp2.getName() + emp2.getidNumber());
ar.add(emp3.getPosition() + emp3.getDepartment() + emp3.getName() + emp3.getidNumber());
ar.add(emp4.getPosition()  + emp4.getDepartment() + emp4.getName() + emp4.getidNumber());
ar.add(emp5.getPosition()  + emp5.getDepartment() + emp5.getName() + emp5.getidNumber());



 
  System.out.println(ar);
  

 
 
 
}

}

Your second post is the wrong way to do things. Your first was correct, but you didn't understand the advice given to you.

for(int i =0;i<ar.size();i++)
{
   Employee emp = ar.get(i);
   System.out.println(emp.getPosition()  + emp.getDepartment() + emp.getName() + emp.getidNumber());
}

When you do this:

for(int i =0;i<ar.size();i++)
{
   Employee emp = ar.get(i);
   System.out.println(emp);
}

The toString method of the Employee class is called. Since you didn't override the method of the Object class is called, which returns what you used to get.
