• Here's the code for the TaxReturn example, first TaxReturn.java:

  package test;
  
  public class TaxReturn
  {
  	private int taxID;
  	private int taxDue;
  	private int refund;
  	public TaxReturn(int taxID, int taxDue, int refund)
  	{
  		super();
  		this.taxID = taxID;
  		this.taxDue = taxDue;
  		this.refund = refund;
  	}
  	@Override
  	public String toString()
  	{
  		return "TaxReturn [taxID=" + taxID + ", taxDue=" + taxDue + ", refund="
  				+ refund + "]";
  	}
  	
  }
  
            

  Next, TestTaxReturn.java:

  package test;
  
  import java.util.ArrayList;
  
  public class TestTaxReturn
  {
  	public static void main(String[] args) {
  		TaxReturn[] returns = new TaxReturn[3];
  		
  		returns[0] = new TaxReturn(1111, 4000, 5000);
  		returns[1] = new TaxReturn(2222, 5000, 68000);
  		returns[2] = new TaxReturn(3333, 6000, 78000);
  		
  		for(TaxReturn t : returns) {
  			System.out.println(t);
  		}
  		
  		System.out.println("*****************************");
  		
  		ArrayList mylist = new ArrayList<>();
  		
  		mylist.add(new TaxReturn(1111, 4000, 5000));
  		mylist.add(new TaxReturn(2111, 5000, 7000));
  		mylist.add(new TaxReturn(3111, 6000, 8000));
  		mylist.add(new TaxReturn(4111, 7000, 9000));
  		
  		for(TaxReturn t : mylist) {
  			System.out.println(t);
  		}
  	}
  }
