Most common checked and unchecked Java Exceptions? [closed]

Answer 1

Assume the below are java.lang unless I specify otherwise:

• Casting: ClassCastException
• Arrays: ArrayIndexOutOfBoundsException, NullPointerException
• Collections: NullPointerException, ClassCastException (if you're not using autoboxing and you screw it up)
• IO: java.io.IOException, java.io.FileNotFoundException, java.io.EOFException
• Serialization: java.io.ObjectStreamException (AND ITS SUBCLASSES, which I'm too lazy to enumerate)
• Threads: InterruptedException, SecurityException, IllegalThreadStateException
• Potentially common to all situations: NullPointerException, IllegalArgumentException

You would do well to look at Java site's Package Summary pages. Here's one: http://java.sun.com/j2se/1.4.2/docs/api/java/io/package-summary.html
