```
```
	g.setColor(Color.red);
```
```
 
```
```
	int wid = 300;
```
```
	int len = 150;
```
```
	//Draw a rectangle

```
	g.drawRect(100,175,wid,len);
```
```
 
```
```
	//Create a font and draw string
```

	Font myFont = new Font("TimesRoman",Font.BOLD,15);

```
	g.setFont(myFont);
```
```

```
```
	String s = "String inside Rectangle";
```
```
	g.drawString(s,150,250);
```
```
    }
```
```
}
```
```
