Is this code right for JAVA?

Answer 1

import java.awt.*;
import java.Applet;
import java.awt.Event.*;

public class CircleDrawer extends Applet implements ActionListener
{
Button goButton;
Button resetButton;
TextField radiusField;
TextField xposField;
TextField yposField;

public void init()
{
goButton = new Button("Generate!");
resetButton = new Button("Reset");
radiusField = new TextField("5",3);
xposField = new TextField("0",2);
xposField = new TextField("0",2);

goButton.addActionListener(this);
resetButton.addActionListener(this);
setBackground(Color.black);
}

public void paint(Graphics g)
{
g.setColor(Color.lime);
g.drawLine(0,128,256,128);
g.drawLine(128,64,128,256);
g.drawArc(xposField.getInt()+128,yposField.getInt()+128,radiusField.getInt()*2,radiusField.getInt()*2,0,360);
g.drawString("Radius:",0,48);
add(radiusField);
g.drawString("X:");
add(xposField);
g.drawString("Y:");
add(yposField);
add(goButton);
add(resetButton);
}

public void actionPreformed(ActionEvent evt)
{
if (evt.getSource() == goButton)
{
repaint();
}
}
}

This is the code
