Remove characters before a comma in a string

Question

I was wondering what would be the best way to go about removing characters before a comma in a string, as well as removing the comma itself, leaving just the characters after the comma in the string, if the string is represented as 'city,country'. Thanks in advance

Accepted Answer

So you want

city,country

to become

country

An easy way to do this is this:

```
public static void main(String[] args) {
    System.out.println("city,country".replaceAll(".*,", ""));
}
```

This is "greedy" though, meaning it will change

city,state,country

into

country

In your case, you might want it to become

state,country

I couldn't tell from your question.

If you want "non-greedy" matching, use

```
System.out.println("city,state,country".replaceAll(".*?,", ""));
```

this will output

state, country
