Java: Splitting a string by whitespace when there is a variable number of whitespaces between words?

Question

I have the following:

String string = \"1-50  of 500+\";
String[] stringArray = string.split(\" \");

Printing out all the elements in this

Answer 1

Your Program is correct but you put two space after 1-50. So Its giving you that output. Remove one space and you are done. No need to change the code. But if there is a two space then you should use string.split("\\s+")

Answer 2

To fix the space problem, after splitting, you can use .trim() to remove the white space.

Something like this should work.

for(int x=0; x<stringArray.length(); x++){
    stringArray[x] = stringArray[x].trim();
}

Answer 3

Use \\s+ to split on spaces even if they are more.

String string = "1-50  of 500+";
String[] stringArray = string.split("\\s+");

for (String str : stringArray)
{
    System.out.println(str);
}

EDIT:

If you also want to split on tabs, change the regex to \\s+|\\t+ and it detects both spaces and tabs as well.

Answer 4

Use this to spilt the String.

String[] stringArray = string.split("\\s+");

Answer 5

String[] stringArray = string.split(" +");

instead of

String[] stringArray = string.split(" ");

Answer 6

You can split using regex

string.split("\\s+");
