What do you mean fetch the String. Since you already have the String, why do you need to fetch it?

Also look at the String API: http://download.oracle.com/javase/1.4.2/docs/api/java/lang/String.html
for methods that you might want to use.

what i mean is string is a mobile no which is entered by user.i want to check the length of it so that arrayIndex out of bound exception can be handled.that why i want fetch enterd moblie no and check it's length.
what i m using for this is

if(length > 12)
        {                //*354*4*9061239405#
                 strRequest = strRequest.substring(7,length-1);
                System.out.println(strRequest);
        }

but sometime when user enter *354*4*96034# then it will give Indexoutof bound exception.I want to print some error message instead of this

Then take the length of the String and use if-else statements as when to call the substring method. The variable length, how do you give it value? Shouldn't be using the String API in order to get the length of the String ?
