String[] a1 = "abc bcd"
String[] seperate = a1.split(" ");
String finalValue = seperate[0];
System.out.pritln("Final string is :" + finalValue);

This will give the result as abc

final String dir = System.getProperty("user.dir");
String[] array = dir.split("[\\\\/]",-1) ;
 String arrval="";

   for (int i=0 ;i<array.length;i++)
      {
        arrval=arrval+array[i];

      }
   System.out.println(arrval);

Please, don't split using file separators.

It's highly recommended that you get the file directory and iterate over and over the parents to get the paths. It will work everytime regardless of the operating system you are working with.

Try this:

String yourDir = "C:\\home\\public\\folder";
File f = new File(yourDir); 
System.out.println(f.getAbsolutePath());
while ((f = f.getParentFile()) != null) {
    System.out.println(f.getAbsolutePath());
}

I guess u can use the StringTokenizer library

String directory="C:\home\public\folder"; 
String [] dir=direct.split("\");
StringTokenizer token = new StringTokenizer(directory, '\');
while(token.hasTokens()
{
    String s = token.next();
}

This may not be completely correct syntactically but Hopefully this will help.

The syntax error is caused because the sing backslash is used as escape character in Java.

In the Regex '\' is also a escape character that why you need escape from it either.

As the final result should look like this "\\\\".

But You should use the java.io.File.separator as the split character in a path. 

String[] dirs = dircect.split(Pattern.quote(File.separator));

split("\\") A backlash is used to escape.

You need to escape it.

String [] dir=direct.split("\\\\");

Edit: or Use Pattern.quote method.

 String [] dir=direct.split(Pattern.quote("\\"))

split() function in Java accepts regular expressions. So, what you exactly need to do is to escape the backslash character twice:

String[] dir=direct.split("\\\\");

One for Java, and one for regular expressions.

You need to escape the backslash: 

direct.split("\\\\");

Once for a java string and once for the regex.

It's because of the backslash. A backslash is used to escape characters. Use

split("\\")

to split by a backslash.
