[FIXED] Java split string to get only two words

Issue

If you have an String, how can you get the first two words.

Example:

 String string = "hello world bye moon", stringTwo;
 String[] newStringArray;
 newStringArray = string.split(" ");
 stringTwo = newStringArray[0] + " " + newStringArray[1];

 System.out.println(stringTwo);

Do you know a short efficient way?

Solution

As an alternative to String#split(), you could use a regex replacement approach:

String string = "hello world bye moon";
String firstTwo = string.replaceAll("(\\w+ \\w+).*", "$1");
System.out.println(firstTwo);  // hello world
