Hi Bucky. I'm new to JAVA and wanted to know from you or anyone on the forum how the java methods such as JOptionPane.showMessageDialog() and getcontentpane() work. These two are just an example of the many methods I find myself not understanding when trying to read code. Is there a document that explains which methods are used when and what they mean? How do I know which method to use when if I'm writing a program of my own?

Thank you and kind regards
