Hi,
I am working on below challenge
http://codingbat.com/prob/p129952
I tried my code as below
public String getSandwich(String str) {
  String Str1 = new String("Welcome to Tutorialspoint.com");
  //String str2=str.replaceFirst("bread", "" );
  //System.out.println(Str.replaceFirst("Tutorials", "" ));
//String strNew= str.repalceFirst("bread", "xyzzz");
String str3=str.replaceAll(".*bread*.", "" );

  return str3;
}

 //System.out.println(Str.replaceFirst("(.*)Tutorials(.*)",
 //                        "AMROOD" ));

 //     System.out.print("Return Value :" );
 //     System.out.println(Str.replaceFirst("Tutorials", "AMROOD" ));
I am getting below result
