Weird data output

[Shaolin]

Hi Guys,

I have a main class, an employee class and a fullTime class which is a subclass of employee. I am trying to output some hard written data in the main class but I get the following characters when I run it:

FT@19821f
FT@addbf1

Here is my code:

Employee Class:

public abstract class Employee {

protected int workid ;
protected String name ;
protected int tel ;
protected static int lastid = 100000 ;
protected double pay ;

public Employee() {
name = "" ;
tel = 0;
workid = lastid++ ;
pay = 0.0 ;
}

public Employee (String nm, int ext) {
name = nm ;
tel = ext ;
workid = lastid++ ;
pay = 0.0 ;
}

public abstract void calculatePayment(); // abstract method

}

FullTime Class:

public class FT extends Employee {

protected static double salary = 1600.0;

public FT () {
super();
}

public FT (String nm, int ext){
super(nm, ext);
}
}

Main Class:

public class main {

public static void main( String[] args )
{
FT e1 = new FT ( "John", 1237 ) ;
FT e2 = new FT ( "Michelle", 1291 ) ;

System.out.println( "test: " + e1 ) ; // Output data

}


}

System.out.println( "test: " + e1 ) ;

You are printing out the class, not any of the data in it.

System.out.println( "test: " + e1.name)

That will only work if the main class is in the same package as everything else (since name is protected).

Thanks. its not in the same package.

What if I want to use a vector/iterator to output the data? I tried it and it gave me the same output outlined in the first post.

What adjustments will I need to make in order to get it to work ?

[staykovmarin]

A solution would be to store all of the data in the Employee class as a single Vector: the name work id, pay, etc.

Then return that data and iterate it.

[Shaolin]

Can you give me an example as this is all new to me. Thanks

[Shaolin]

I tried the following:

   	ListIterator vIter = vec.listIterator() ;
   	while ( vIter.hasNext() )
      {
         System.out.println( vec ) ;
         vIter.next() ;
      }

And I got this output:

[FT@19821f, FT@addbf1]
[FT@19821f, FT@addbf1]

Here is the whole code for Directory(storage):

[staykovmarin]

Well all these variables are different types at the moment:

protected int workid ;
protected String name ;
protected int tel ;
protected static int lastid = 100000 ;
protected double pay ;

You those all have to become Strings and be placed inside a vector. I dont know if you want that but here is an example:

		String s = "s";
		int i = 5;
		Vector<String> data = new Vector<String>();
		data.add(s);
		data.add(String.valueOf(i));

		Iterator<String> ir = data.iterator();
		while(ir.hasNext())
			System.out.println(ir.next());

[staykovmarin]

I tried the following

Good try, but you are printing out the vector, not the item inside it. You need to print out the content of the vector if you want to see any meaningful data. So you need:

System.out.println(vec.next());

[Shaolin]

I tried that and got the following error:

Directory.java:56: cannot find symbol
symbol : method next()
location: class java.util.Vector<Employee>
System.out.println(vec.next());

[staykovmarin]

The next() method is not part of Vector, its part of Iterator:

		Vector<Employee> data = new Vector<Employee>();
		Iterator<String> ir = data.iterator();
		while(ir.hasNext())
			System.out.println(ir.next());

[Shaolin]

That didn't work. Here are the error messages I get:

Directory.java:59: incompatible types
found   : java.util.Iterator<Employee>
required: java.util.Iterator<java.lang.String>
    Iterator<String> vIter = vec.iterator() ;
                                         ^

[Shaolin]

OK so I've been messing around with the code and I this is what I have at the moment:

      ListIterator vIter = vec.listIterator() ;

      while ( vIter.hasNext() )
      {
         System.out.println( vIter.next() ) ;
      }

It works, but the output is as follows:

FT@19821f
FT@addbf1

I know that Im printing the vector, not the actual content. How do I print the content ?

[Shaolin]

Fixed problem.
