Java replaceALL for string

Question

I have a string:

100-200-300-400

i want replace the dash to "," and add single quote so it become:

 '100','200','300','400'

My current code only able to replace "-" to "," ,How can i plus the single quote?

String str1 = "100-200-300-400"; 
split = str1 .replaceAll("-", ",");
if (split.endsWith(",")) 
{
 split = split.substring(0, split.length()-1);
}

Answer 1

You can use

split = str1 .replaceAll("-", "','");
split = "'" + split + "'";

• hades: that will only quote whole string into 1 single quote, '100,200,300,400'
• Eran: @user3172596 I tested it and got '100','200','300','400'. The replaceAll call adds the remaining single quotes. Note that it's not the same replaceAll call as in your question.

Answer 2

As an alternative if you are using java 1.8 then you could create a StringJoiner and split the String by -. This would be a bit less time efficient, but it would be more safe if you take, for example, a traling - into account.

A small sample could look like this.

String string = "100-200-300-400-";
String[] splittet = string.split("-");
StringJoiner joiner = new StringJoiner("','", "'", "'");
for(String s : splittet) {
 joiner.add(s);
}
System.out.println(joiner);

• hades: is there any solution for java 1.6? not using java 1.8
• SomeJavaGuy: @user3172596 it isn´t included inside the 1.6 jdk sadly. You´d need to go for regex otherwise. The solution provided by Eran should work.

Answer 3

This will work for you :

public static void main(String[] args) throws Exception {
 String s = "100-200-300-400";
 System.out.println(s.replaceAll("(\\d+)(-|$)", "'1ドル',").replaceAll(",$", ""));
}

O/P :

'100','200','300','400'

Or (if you don't want to use replaceAll() twice.

public static void main(String[] args) throws Exception {
 String s = "100-200-300-400";
 s = s.replaceAll("(\\d+)(-|$)", "'1ドル',");
 System.out.println(s.substring(0, s.length()-1));
}

• hades: is ur regex limited to only integer? my value might be: ***-100-TSK-534
• TheLostMind: @user3172596 - You can replace \\d+ with [a-zA-Z]+ if you have values like abc-asa etc
