program not working

[Dax Le Foundry]

I am learning java and I decided to challenge myself with a business program for listing employees and their ages using arrays. I named my files test and testone(the class with main).

test.java

// africom business employee list

import java.util.*;

public class test
{
	 Scanner input = new Scanner(System.in);
	 int number_of_empl;
	 String emplName[] = new String[number_of_empl];
	 int l = emplName.length;
	 
	 int age[] = new int[number_of_empl];
	
	public void number_of_emplyz(int num)
	{
		number_of_empl = num;
	}
	
	public void setEmpl() // set employee name and age
	{
		
		for(int count = 0; count < l; count++)
		{
			System.out.println("Enter name: ");
			System.out.println();
			emplName[count] = input.nextLine();
			
	
		}
		
		for(int i=0; i<l; i++)
		{
			System.out.println("Enter " + age[i]);
			System.out.println("'s age");
		}
	}
	
	public void greet() // print greet messege
	{
		System.out.println("WELCOME TO AFRICOM EMPLOYEE REGISTER");
	}
	
	public void header() // print header
	{
		char tab = '\t';
		
		System.out.print("Name");
		System.out.print(tab);
		System.out.print("Surname");
		System.out.print(tab);
		System.out.print("Age");
		System.out.println();
	}
	
	public void getEmpl() // dispay table of employees
	{
		char tab = '\t';
		for(int count = 0; count < emplName.length; count++)
		{
			System.out.println(emplName[count] + tab + age[count]);
			
			
		}
	}
}

testone.java

// testing the app
import java.util.*;

public class testone
{
	public static void main(String[] args)
	{
		Scanner input = new Scanner(System.in);
		test africom = new test();
		africom.greet();
		System.out.println("Enter number of Employees");
		int x;
		x = input.nextInt();
		africom.number_of_emplyz(x);
		africom.setEmpl();
		africom.header();
		africom.getEmpl();
	}
}

output is

WELCOME TO AFRICOM EMPLOYEE REGISTER
Enter number of Employees
4
Name    Surname Age

Process completed.

Please Help

Do you have any questions or problems?
What do you expect the output to look like?

You need to show the full console/command prompt with the data that was entered into the program.
To copy the contents of the command prompt window:
Click on Icon in upper left corner
Select Edit
Select 'Select All' - The selection will show
Click in upper left again
Select Edit and click 'Copy'

Paste here.

Hey Norm. I am expecting the program to ask me to enter a name of the employees, using the for loop to ask me the names up to the number I gave it when it asks me "How may Employees". then it should ask me the age of each employee.
Here is the console output

The program uses the length of the array to determine how many times to ask for a name.
Because of the way the program is coded, the length is 0. So it does not ask for any names.
You have created the arrays BEFORE there is a size for them. When the class is created, the arrays are given the size as set by a variable with the value of 0.

You need to change the logic so you don't create the arrays until you have a size to give them.
Define the variables in the class:
String emplName[]; // define the array variable

and then when you have the size:

emplName = new String[theSize]; // give the variable a value

Norm its not working. can you code it for me and run it and show me the output.

Are you going to pay Norm for that? This is the way we all play the game: you do the coding; you get stuck; you ask a clear question and we try to help you out.

kind regards,

Jos
