Pattern and Matcher Class Example

import java.util.regex.*;
class T
{
public static void main(String args[])
{
//Example of Regular Expression
Pattern p=Pattern.compile("[w|W]{3}[.][a-zA-Z0-9]+[.][a-zA-Z0-9]+");
Matcher m=p.matcher(args[0]);
System.out.println(m.matches());

m=m.usePattern(Pattern.compile("[w]{3}[.][a-zA-Z0-9]+[.][a-zA-Z0-9]+"));
System.out.println(m.matches());

//Example of Split Function
Pattern p1=Pattern.compile("[ @.]");
String str[]=p1.split(args[1]);

for(String s:str)
System.out.println(s);

System.out.println(Pattern.matches("ab", "aaaaab"));
}
