Java Regex

Write a class called myRegex which will contain a string pattern. You need to write a regular expression and assign it to

the pattern such that it can be used to validate an IP address. Use the following definition of an IP address:

IP address is a string in the form "A.B.C.D", where the value of A, B, C, and D may range from 0 to 255. Leading zeros are

allowed. The length of A, B, C, or D can't be greater than 3.

Some valid IP address:

000.12.12.034

121.234.12.12

23.45.12.56

Some invalid IP address:

000.12.234.23.23

666.666.23.23

.213.123.23.32

23.45.22.32.

I.Am.not.an.ip

In this problem you will be provided strings containing any combination of ASCII characters. You have to write a regular

expression to find the valid IPs.

Just write the myRegex class, and we will append your code after the following piece of code automatically before running it:

class myRegex

{

String pattern = "^(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$";

}
