<p>Hey, I took Comp Sci A last year and I'm self-studying Comp Sci AB this year. I think Barron's is the best source of information. Also, download a Java program if you haven't done so already (JCreator and Dr.Java are good -- google them and download one). Practice writing and testing code (practice is important). Also, go to apcentral.collegeboard.com, create a teacher account so you get access to past exams, look at the part 2 questions and try doing them out. </p>

<p>That's all the advice I have for you. Studying for the comp sci A exam yourself is plausible if you have the motivation. It's not a difficult exam. Hope I helped.</p>

very nice. the lower left window has the list for all the classes. click on a class and you can learn about it's methods and constructors. Like if there is a particular method of String you need, go to" String" and click it. scroll down and they tell u all kinds of good stuff</p>

<p>sorry if that made no sense. I suck at comp sci</p>

<p>i just recieved BIG JAVA in the mail. what an awesome book. i recommend it to everyone.</p>

<p>i want to read a string. ie: reader.readString(); or something or that sort but compiler says it does not exists. is it just wrong syntax or do i need to dl a class?</p>

<p>To use some i/o functions you need to import parts of the java.io package. There's no class to download as these are part of the core API, but you just need to import them before using them.</p>

<p>id added: import java.*</p>

<p>but reader.readString still does not work.</p>

<p>You can't import java.* because each package need to be imported separately. For instance, importing java.awt.* does not import any of the classes in java.awt.event.<em>. Those two are completely different packages and importing the parent does not import the child. Similar with java.io.</em>.</p>
