JAVA Must convert both from BASE2 to BASE10 and BASE10 to BASE2 and handle errors for both. Use popups to display error conditions. After the user responds to the popup, clear the bad data and position the curser for new input. Define and throw your own NotInBinaryFormatException to handle the BASE2 -> BASE10. Use NumberFormatException to handle BASE10 -> BASE2. Be sure your error messages appear on the same monitor and over the converter application. Using the code below: import java.awt.event.*;

import java.awt.*;

import javax.swing.*;
