How to Split words and separate the ones with a certain letter?

In my program i want to take an input from a user, and separate the words with the letter "e" in them and concatenate them without any spaces or different lines. For instance, if my input was "Rob is a nice person" I want it to print "niceperson". This is what i have so far:

Scanner kybd = new Scanner(System.in);
String s = kybd.nextLine();
String[] arr = s.split(" ");    
for ( String ss : arr) {
    String []ary = {ss};
    for(int i = 0; i < ss.length(); i++){
        if(ary[i].equalsIgnoreCase("e")){
            System.out.print(ary);
        }
    }
}

Thanks for any tips or help!

how about some method like string.Replace("e ", "e"); I assume you are using String static method, as I can see you are using Split

You can do it in this way

    String str = "Rob is a nice person";
    String[] arr = str.split(" "); // split by space
    StringBuilder sb = new StringBuilder();
    for (String i : arr) {
        if (i.contains("e")) { // if word contains e
         sb.append(i);// append that word 
        }
    }
    System.out.println(sb);

Out put:

   niceperson

Use the contains method, it works like this:

Scanner kybd = new Scanner(System.in);
StringBuilder result = new StringBuilder();
String s = kybd.nextLine();
String[] arr = s.split(" ");
 for ( String ss : arr) {
     if(ss.contains("e")) {
         result.append(ss);
     }
}
