Hey, mostly done with my project, but I'm having a hard time trying to get my window to look like what it is above. Below is my Java program. Can you help? Thanks.

import javax.swing.*; //for swing classes

import java.awt.BorderLayout;
import java.awt.event.*; //for event handling

public class LeavinesPropertyTax extends JFrame
{
   private JPanel panel; // to hold components
   private JLabel actualValueLabel;

Explanation / Answer

Steps to get the desired screen:
1. Create a label, name it as "Property Tax" and select Properties-> border->choose Line border
2. Create a label and name it as "Enter the property value"
3. Create a text field, select Properties-> border->choose Line border. Choose edit text and clear the textfield content
4. Create two buttons, name them as "Calculate Assessmet value" and "Calculate
property tax". Then select Properties -> border->choose Line border. Then deselect the contentAreaFilled checkbox.
5. To set boreder for the jframe use coding part. Include
import javax.swing.BorderFactory;
import java.awt.Color;

Then in the frame constructor, include the following line of code:

getRootPane().setBorder(BorderFactory.createMatteBorder(1, 1, 1, 1, Color.BLACK));
