How to get the desired character from variable-sized strings?

Question

I need to extract the desired line attached to the word.

for example

 pot-1_Sam  
 pot-22_Daniel
 pot_444_Jack
 pot_5434_Bill

I need to get the names from the lines above. Sam, Daniel, Jack and Bill. The fact is that if I use a substring, the position continues to change due to the length of the number. How to use them with REGEX.

Update: Some lines have 2 options for underlining, for example

 pot_US-1_Sam  
 pot_RUS_444_Jack

Answer 1

Your Answer:

String[] s = new String[4];
s[0] = "pot-1_Sam";
s[1] = "pot-22_Daniel";
s[2] = "pot_444_Jack";
s[3] = "pot_5434_Bill";
ArrayList<String> result = new ArrayList<String>();
for (String value : s) {
    String[] splitedArray = value.split("_");
    result.add(splitedArray[splitedArray.length-1]);
}

for(String resultingValue : result){
    System.out.println(resultingValue);
}

Answer 2

, . , - , lastIndexOf substring.

 String result = yourString.substring(yourString.lastIndexOf("_")+1, yourString.length());
