- A text is scanned quickly in order to find a specific piece of information. In daily life, scanning is regularly used for tasks like looking up a word in a dictionary or finding a friend's name in your phone's contacts list.
- Scanners may basically be divided into three categories. These consist of network scanning, port scanning, and vulnerability scanning.
- There are three different types of scanners: portable scanners, flatbed scanners, and drum scanners. While flatbed scanners are commonly used in offices and classrooms, drum scanners are mainly used in the publishing industry to print high-quality pictures.
- Three processes make up the basic scanning process: scan, register, and detail.

public int color;
public int numtyres;
public void type()
{
if(numtyres==2)
{
system.out.println("Two wheeler");
}
else if(numtyres==3)
{
system.out.println("Three wheeler");
}

system.out.println("four wheeler");
}
