How to split a String by space

Question

I need to split my String by spaces. For this I tried:

str = \"Hello I\'m your String\";
String[] splited = str.split(\" \");

But it doesn\

Answer 1

An alternative way would be:

import java.util.regex.Pattern;

...

private static final Pattern SPACE = Pattern.compile(" ");
String[] arr = SPACE.split(str); // str is the string to be split

Saw it here

Answer 2

if somehow you don't wanna use String split method then you can use StringTokenizer class in Java as..

    StringTokenizer tokens = new StringTokenizer("Hello I'm your String", " ");
    String[] splited = new String[tokens.countTokens()];
    int index = 0;
    while(tokens.hasMoreTokens()){
        splited[index] = tokens.nextToken();
        ++index;
    }

Since it's been a while since these answers were posted, here's another more current way to do what's asked:

List<String> output = new ArrayList<>();
try (Scanner sc = new Scanner(inputString)) {
    while (sc.hasNext()) output.add(sc.next());
}

Now you have a list of strings (which is arguably better than an array); if you do need an array, you can do output.toArray(new String[0]);

Answer 4

What you have should work. If, however, the spaces provided are defaulting to... something else? You can use the whitespace regex:

str = "Hello I'm your String";
String[] splited = str.split("\\s+");

This will cause any number of consecutive spaces to split your string into tokens.

As a side note, I'm not sure "splited" is a word :) I believe the state of being the victim of a split is also "split". It's one of those tricky grammar things :-) Not trying to be picky, just figured I'd pass it on!

Simple to Spit String by Space

    String CurrentString = "First Second Last";
    String[] separated = CurrentString.split(" ");

    for (int i = 0; i < separated.length; i++) {

         if (i == 0) {
             Log.d("FName ** ", "" + separated[0].trim() + "\n ");
         } else if (i == 1) {
             Log.d("MName ** ", "" + separated[1].trim() + "\n ");
         } else if (i == 2) {
             Log.d("LName ** ", "" + separated[2].trim());
         }
     }

Answer 6

Use Stringutils.split() to split the string by whites paces. For example StringUtils.split("Hello World") returns "Hello" and "World";

In order to solve the mentioned case we use split method like this

String split[]= StringUtils.split("Hello I'm your String");

when we print the split array the output will be :

Hello

I'm

your

String
