Question

Well it is hard to explain,
I searched the internet for the answer, unfortunately I can’t find any, maybe because I don’t know what is it called though.

It’s like
url.CONTAINS
url.STARTSWITH

What’s the capitalized thing called? Class? Object?
Plus, if it’s possible if I can get a list of things to put after url.”Class/Object/Whatever it is called”.

Answer 1

url is an instance of a class, and contains and startsWith are public variables as they do not have parentheses after them. However, I think you may have accidentally ommitted those, in which case contains() becomes a member function (aka method aka function) of the url class.

Both of the example methods you gave are part of the String class. An example usage would be:

String url = "http://www.google.com"; //create an object of the String class with the name url
if(url.startsWith("http")) {
    Log.d("MyApp", "This URL uses the http protocol");
}
