Use the API documentation ?
Dear all,
I am still learning the basic of java. I see a question in the java totural .
Question 1: Use the API documentation to find the answers to the following questions:
a. What Integer method can you use to convert an int into a string that expresses the number in hexadecimal? For example, what method converts the integer 65 into the string "41"?
I see the answer, but I have no clue how to use the API documentation to find the answers. PLease help :)

Go to the docs for Integer.
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Integer.html
Scan down through the methods for one that takes at least a String as an arg, read their synopses. One of them will match what's described.
That's how we find what we're looking for in general, in core API and in 3rd party APIs, and even in libraries that we write ourselves--pick a likely class, scan through its methods, look at signatures, return types, and synopses to see if there's one (or more) that might do what we want.
