Easiest way to get every word except the last word from a string

Question

What is the easiest way to get every word in a string other than the last word in a string?

Up until now I have been using the following code to get the last word:

String listOfWords = "This is a sentence";
String[] b = listOfWords.split("\\s+");
String lastWord = b[b.length - 1];

And then getting the rest of the the string by using the remove method to remove the last word from the string.

I don't want to have to use the remove method. Is there a way similar to the above set of code to get the string of words without the last word and last space?

Answer 1

Like this:

    String test = "This is a test";
    String firstWords = test.substring(0, test.lastIndexOf(" "));
    String lastWord = test.substring(test.lastIndexOf(" ") + 1);

Answer 2

You could get the lastIndexOf the white space and use a substring like below:

String listOfWords = "This is a sentence";
int index = listOfWords.lastIndexOf(" ");
System.out.println(listOfWords.substring(0, index));
System.out.println(listOfWords.substring(index+1));

Output:

        This is a
        sentence

Answer 3

Try using the method String.lastIndexOf in combination with String.substring.

String listOfWords = "This is a sentence";
String allButLast = listOfWords.substring(0, listOfWords.lastIndexOf(" "));
