How split values of ArrayList?

Question

I am getting a list of data in a loop. For example :

List<String> and the values is :

abc{+6636593}
jkihe{qwsd223awq}
......
......etc

I need to have:

abc
jkihe

I write this code :

ArrayList<String> values = new ArrayList<String>();
for(String valueone : valuetwo){
     values.add(valueone);
}

Above code work good but below code get me crash :

for (int i = 0; i < values.size(); i++) {
    Log.i("test" , values.get(i).split("{")[0]); <==== HERE GET ME CRASH
}

So what exactly is your question? Any error message when your code gets you crash? — user1438038

String#split() accepts regex as parameter, you need to escape {.
Try this Log.i("test" , values.get(i).split("\\{")[0]);

Here is an answer with enhanced for loop and without regex

for(String test: values) {
   Log.i("test", test.replace(test.substring(test.indexOf("{")), ""));
}

Hope this was helpful!

more efficient: Log.i("test", values.get(i).substring(0, values.get(i).indexOf('{')));
