Java/android noob, passing variables to function
Okay so I'm VERY new to java and I'm trying to make a very simple android program. Basically I have a function, it will take in two integers and then display their product. But I don't think I'm passing the variables to the function correctly. Also I'm probably not converting the numbers to strings the right way (there doesn't appear to be a string datatype in standard java so i need some sort of library or something i assume).
Anyways here's the code
public class helloagain extends Activity
public void onCreate(Bundle savedInstanceState)
public void FUNCTION_1(int A,int B)
TextView tv = new TextView(this);

What makes you think that? Does it not compile, does it not work? Unless you tell us what is wrong we can't help you fix it.

There is a String class for handling strings. If you want to convert numbers to a String there are a few ways of doing it. One way is to use the String class which has a set of overloaded valueOf(..) methods which you can use to convert primitives to a string representation of the value.

Read the API docs for java.lang.String.
And whilst you are reading stuff, read up on Java naming conventions or people are going to struggle to read your code.
