In Java "mar\12\2013" is an invalid string.

To use mar\12\2013 in Java, you need "mar\\12\\2013".

If you are taking input from user as "mar\12\2013", then also you have to split it with \\\\.

Reason : .split() takes regex as a parameter.

  • To specify \ in regex, we need \\, because \ is an escape character in regex.

  • Also, \ is an escape character in Java, so we need to escape both \ of \\, which makes it \\\\.

    String s1= //take input from user                 // "mar\12\2013"
String[]s=s1.split("\\\\");
for(String s2:s) {
    System.out.println(s2);
}

The above code will work the way you wish.

See the working code here.

See the below code it worked fine for me

public class StringTest {

        public static void main(String arg[]){
         String s1="mar\\12\\2013";
            String[]s=s1.split("\\");
            for(String s2:s){

                System.out.println(s2);

            }
        }
    }

String s1="mar\12\2013";
String[]s=s1.split("\\");
for(String s2:s){
    System.out.println(s2);
}

You doubled up the selectors, i cant actually test atm but i believe it just needs the 2, the first escaping the second.
