JAVA : comparaison de deux String de formats différents

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

public class Test
{
    private static final Pattern PATTERN_1 = Pattern.compile("[A-Z]+-([0-9]+)([a-z]+[0-9]+)");
    private static final Pattern PATTERN_2 = Pattern.compile("([0-9]+)-([A-Z]+[0-9]+)");
    
    public static String convert(String str)
    {
        Matcher matcher1 = PATTERN_1.matcher(str);
        if (matcher1.matches())
            return matcher1.group(1) + matcher1.group(2);
        
        Matcher matcher2 = PATTERN_2.matcher(str);
        if (matcher2.matches())
            return matcher2.group(1) + matcher2.group(2).toLowerCase();
        
        return str;
    }
    
    public static boolean compare(String str1, String str2)
    {
        return convert(str1).equals(convert(str2));
    }
    
    public static void main(String[] args)
    {
        String str1 = "10-CHAINE3";
        String str2 = "AA-10chaine3";
        
        System.out.println(convert(str1)); // 10chaine3
        System.out.println(convert(str2)); // 10chaine3
        System.out.println(compare(str1, str2)); // true
    }
}

 String a = "looool";
  
 if(a.matches(".*ooo.*")){
  System.out.println("ok");
 }

function (String s="AA-10chaine3") {

     traitement...

     si correspondance entre s et "10-CHAINE3" on retourne vrai

}
