Splitting string on multiple spaces in java [duplicate]

Answer 1

You can use Quantifiers to specify the number of spaces you want to split on: -

    `+` - Represents 1 or more
    `*` - Represents 0 or more
    `?` - Represents 0 or 1
`{n,m}` - Represents n to m

So, \\s+ will split your string on one or more spaces

String[] words = yourString.split("\\s+");

Also, if you want to specify some specific numbers you can give your range between {}:

yourString.split("\\s{3,6}"); // Split String on 3 to 6 spaces

Answer 2

I am giving you another method to tockenize your string if you dont want to use the split method.Here is the method

public static void main(String args[]) throws Exception
{
    String str="This is     different type   of file.Can not split  it    using ' '(white space)";
    StringTokenizer st = new StringTokenizer(str, " "); 
    while(st.hasMoreElements())
    System.out.println(st.nextToken());
}
 }

Answer 3

you can use regex pattern

public static void main(String[] args)
{
    String s="This is     different type   of file.";
    String s1[]=s.split("[ ]+");
    for(int i=0;i<s1.length;i++)
    {
        System.out.println(s1[i]);
    }
}

output

This
is
different
type
of
file.

Answer 4

Use a regular expression.

String[] words = str.split("\\s+");

Answer 5

String spliter="\\s+";
String[] temp;
temp=mystring.split(spliter);

Answer 6

you can use
replaceAll(String regex, String replacement) method of String class to replace the multiple spaces with space and then you can use split method.
