String utils split - linux

Below Java code works in Windows machine

filepath = "euro\football\france\winners.txt";
String[] values = StringUtils.split(filePath, "\\");

if (values != null && values.length >= 4) {

} else {
    //error
}

But facing issue in linux while executing the code. if loop is not executing, else loop is executing.

Do we need to give split as "\" or "/" for linux

String[] values = StringUtils.split(filePath, "\\");

Any suggestion will be helpful

If the file is on the machine the JVM is running then you can use File.separatorChar to get the system-dependend separator of the local machine.

    String[] values = StringUtils.split(filePath, File.separator);

The JavaDoc says (File.separatorChar):

The system-dependent default name-separator character. This field is initialized to contain the first character of the value of the system property file.separator. On UNIX systems the value of this field is '/'; on Microsoft Windows systems it is '\'.

To avoid that I would use simple regex [/\\] which will split either with / or \, like this :

String[] filePaths = {
        "euro/football/france/winners.txt",   //linux path
        "euro\\football\\france\\winners.txt" //windows path
};
for (String filePath : filePaths) {
    String[] values = filePath.split("[/\\\\]");
    System.out.println(Arrays.toString(values));
}

Outputs

[euro, football, france, winners.txt]
[euro, football, france, winners.txt]
