JAVA pattern match pattern search split example

import java.util.regex.Matcher;
import java.util.regex.Pattern;

// Check if input match a pattern

Pattern curPat = Pattern.compile( "tanvir"+ "(.)+" + "tanvir");
Matcher mymatcher;

String input="tanvirAAAAAAAtanvir";
mymatcher = curPat.matcher( input );

if(mymatcher.find())
{
        System.out.println("Matched pattern: "+ input );
                   
}
// List all hit with position in input string
m=  ConstantValue.patReplicaFantom.matcher(colNameUnReadable) ;
 while (m.find()) {
                        System.out.print("Start index: " + m.start());
                        System.out.print(" End index: " + m.end());
                        System.out.println(" Found: " + m.group());
 }

// Split a input according to pattern

Pattern patFastaHeade = Pattern.compile("[>_]+"); 
String text=">aaaa";
String tmp[];
tmp = patFastaHeade.split(text);
for( int i=0; i < tmp.length ; i++) }
              System.out.println( tmp[i] );
