public class abcd {
      
      public static void main(String[] args){
            RE re =new RE("^[0-9]+[A-Za-z]+|[A-Za-z]+[0-9]+[A-Za-z]+|[A-Za-z]+[0-9]$");
            System.err.println(re.match("manish123"));//true
            System.err.println(re.match("222man"));//true
            System.err.println(re.match("manish"));//false
            System.err.println(re.match("222"));//false
            System.err.println(re.match("man5man"));//true
            System.err.println(re.match("';''"));//false
            
      }
            
}


manish123 is coming as false. I need it true.
