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't seem to work.

Answer 1

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

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;
    }

Answer 3

I do believe that putting a regular expression in the str.split parentheses should solve the issue. The Java String.split() method is based upon regular expressions so what you need is:

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

Answer 4

Here is a method to trim a String that has a "," or white space

private String shorterName(String s){
        String[] sArr = s.split("\\,|\\s+");
        String output = sArr[0];

        return output;
    }

Very Simple Example below:

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

var splited2=splited[1]; //I'm
var splited3=splited[2]; //your
var splited4=splited[3]; //String

Try
