Cannot resolve symbol class graphics

Question

does anyone know what the error
cannot resolve symbol class graphics means?
with this code i can't seem to call the graphics method to draw the line....any reason why?
import javax.swing.*;
import java.*;
public class LineDraw extends JFrame {
    public static void main(String[] args) {
        LineDraw ld = new LineDraw();
        ld.setSize(500,500);
        ld.setVisible(true);
        ld.enterVariables();
    public void init(){
    private int x1;
    private int x2;
    private int y1;
    private int y2;
    public void paint(Graphics g) {
        g.GetGraphics(g);
        super.paintComponent(g);
        g.drawLine(x1, y1, x2, y2);
    public void enterVariables() {
        x1 = Integer.parseInt(JOptionPane.showInputDialog("Enter x1:"));
        y1 = Integer.parseInt(JOptionPane.showInputDialog("Enter y1:"));
        x2 = Integer.parseInt(JOptionPane.showInputDialog("Enter x2:"));
        y2 = Integer.parseInt(JOptionPane.showInputDialog("Enter y2:"));
        repaint();
}

Answer 1

well the exact error message is ...by the way now that i think about it
if the graphics method shoudl not be part of the JFrame class then what method would i use to draw 2D Graphics?
