Remove string after last slash in JAVA

Question

I have a problem with removing everything after the last slash of URL in JAVA For instance, I have URL:

http://stackoverflow.com/questions/ask

n' I wanna change it to:

http://stackoverflow.com/questions/

How can I do it.

Have you tried anything? At least gone through the String API? — Rohit Jain, Aug 09 '13 at 08:21
Use String.lastIndexOf(String) to find the last slash and then select the substring till there...? Takes about 10 seconds to find in the String API... — sheltem, Aug 09 '13 at 08:21

You can try this

    String str="http://stackoverflow.com/questions/ask";
    int index=str.lastIndexOf('/');
    System.out.println(str.substring(0,index));

IF you want to get the last value from the uRL

String str="http://stackoverflow.com/questions/ask";
System.out.println(str.substring(str.lastIndexOf("/")));

Result will be "/ask"

If you want value after last forward slash

String str="http://stackoverflow.com/questions/ask";
System.out.println(str.substring(str.lastIndexOf("/") + 1));

Result will be "ask"

Try using String#lastIndexOf()

Returns the index within this string of the last occurrence of the specified character.

String result = yourString.subString(0,yourString.lastIndexOf("/"));

@RohitJain Your right definitely overkill – ug_ Aug 09 '13 at 08:28
Yes,I always go for regex when only there is no built-in methods available. – Suresh Atta Aug 09 '13 at 08:32

if (null != str && str.length > 0 )
{
    int endIndex = str.lastIndexOf("/");
    if (endIndex != -1)  
    {
        String newstr = str.subString(0, endIndex); // not forgot to put check if(endIndex != -1)
    }
}
