Comparing strings in java android

Question

How do I compare the String

http://192.168.74.1/sp/info.php?prodnum=0000000001

with

http://192.168.74.1

I only need to get the http://192.168.74.1 part of first string.

Answer 1

You don't need to extract anything from the first string. You can use String.startsWith:

if (string1.startsWith(string2)) {
  // do something
}

Answer 2

1) you can use beginwith function

String Mainstring= "http: // 192.168.74.1/sp/info.php?prodnum=0000000001";
if (Mainstring.startsWith("http: // 192.168.74.1"))
 {
 //Write your code here
 }

2) you can use contains function

boolean retval = Mainstring.contains(cs1);

retval will be true if it exist otherwise false.
