public void drawRect(int x, int y, int width, int height): draws a rectangle with the specified width and height.
public abstract void fillRect(int x, int y, int width, int height): is used to fill rectangle with the default color and specified width and height.
public abstract void drawOval(int x, int y, int width, int height): is used to draw oval with the specified width and height.
public abstract void fillOval(int x, int y, int width, int height): is used to fill oval with the default color and specified width and height.
public abstract void drawLine(int x1, int y1, int x2, int y2): is used to draw line between the points(x1, y1) and (x2, y2).
public abstract boolean drawImage(Image img, int x, int y, ImageObserver observer): is used draw the specified image.
public abstract void drawArc(int x, int y, int width, int height, int startAngle, int arcAngle): is used draw a circular or elliptical arc.
public abstract void fillArc(int x, int y, int width, int height, int startAngle, int arcAngle): is used to fill a circular or elliptical arc.
public abstract void setColor(Color c): is used to set the graphics current color to the specified color.
public abstract void setFont(Font font): is used to set the graphics current font to the specified font.
Do remember few of then it will help you.

A Simple Example –

import java.applet.Applet;
import java.awt.*;
public class GraphicsDemo extends Applet
{
public void paint(Graphics g){
g.setColor(Color.red);
g.drawString(“Welcome”,50, 50);
g.drawLine(20,30,20,300);
g.drawRect(70,100,30,30);
g.fillRect(170,100,30,30);
g.drawOval(70,200,30,30);

g.setColor(Color.pink);
g.fillOval(170,200,30,30);
g.drawArc(90,150,30,30,30,270);
g.fillArc(270,150,30,30,0,180);
}
}
