How to cut and replace String

Question

I have a following string which I have to split and replace with "/" on some condition**

String date = "20131105";

I want to change these string to "2013/11/05"

Edit:

I mean variable date must be String not Date data type

do you want to change dates or want to do similar operation on any string? if dates then look at SimpleDateFormat http://stackoverflow.com/a/9872444/1544069 — ritesh, Nov 05 '13 at 08:13
its better to use date format rather then using substring operation in this purpose. — Mustakimur Khandaker, Nov 05 '13 at 08:45

Do like this

Date date = new SimpleDateFormat("yyyyMMdd").parse("20131105");
String formattedDate = new SimpleDateFormat("yyyy/MM/dd").format(date);
System.out.println(formattedDate);

Output

2013/11/05

Use the substring method.

date = date.substring(0, 4) + "/" + date.substring(4, 6) + "/" + date.substring(6, 8);

See you have many logics .. you can use any one..

for example answer from prabhakaran which is

Date date = new SimpleDateFormat("yyyyMMdd").parse("20131105");
String formattedDate = new SimpleDateFormat("yyyy/MM/dd").format(date);
System.out.println(formattedDate);

here you can do one change like this

Date date = new SimpleDateFormat("yyyyMMdd").parse(StringVaribale);
String formattedDate = new SimpleDateFormat("yyyy/MM/dd").format(date);
System.out.println(formattedDate);

here you are converting to date and then converting back to string

Another one is you can take a substring and add "/" into your string in this logic you should take StringBuffer insteed of string. because this is having some extra feature.
