How do I compare the String
http://192.168.74.1/sp/info.php?prodnum=0000000001

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

You don't need to extract anything from the first string. You can use String.startsWith:
if (string1.startsWith(string2)) {
// do something
}

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.

you can do
let
str = "http://192.168.74.1/sp/info.php?prodnum=0000000001"
then
if(str.contains("http://192.168.74.1/"))
{
//do what you want
}

If you need to check if the String Str starts with another string try:
Str= "http: // 192.168.74.1/sp/info.php?prodnum=0000000001";
if (Str.startsWith("http: // 192.168.74.1"))
{
//do something here
}

Consider you have String1 and String2.
To check if String1 starts with String2 , simply use String1.startsWith(String2) method
Here is the example:
String str = "abcd";
String newstr = "ab";
boolean flag = str.startsWith(newstr); // returns true
Please comment for further help.

use
if(aString.contains("http://192.168.74.1")){
//do something here
}

Although checking .startsWith(...) is sufficient, since you want to match urls, it is better to parse the url and break it into components. This can be done manually, using regular expressions, but it is probably safer to use the java url parser. See parsing a URL for details.
