java split does not get empty when backslash separator

i have to split a string based on backslash separator
i have the following value

value=Alex\\patricia

and the value in the middle sometimes is valued ,but in this case does not have a value ,it s ignored by java
instead of having three tokens ,i have only two .

String[] tokens = StringUtils.split(value, '\\');

so i get

tokens[0]=Alex
tokens[1]=Alex=patricia

thanks

Try just using standard java classes

    String value="Alex\\patricia";
    String[] tokens = value.split("\\\\");
    for (String str : tokens) System.out.println(str);

output

Alex
patricia

That's how split from StringUtils works

> Adjacent separators are treated as one separator

You can use Java's String split instead.

String value = "Alex\\\\patricia";
String[] tokens = value.split("\\\\"); // must be escaped since it's a regex

Example jshell session:

jshell> String value="Alex\\\\patricia";
value ==> "Alex\\\\patricia"

jshell> String[] tokens = value.split("\\\\");
tokens ==> String[3] { "Alex", "", "patricia" }
