Most common checked and unchecked Java Exceptions?

Question

I know there is no way to find out which exceptions a method throws without looking up the API docs one-by-one. So, I would like to ask you which are the most common Exceptions and runtime exceptions you have come across when dealing with:

• Casting

• Arrays

• Vector, ArrayList, HashMap, etc.

• IO

• Object Serialization

• Threads

Answer 1

Assume that the below things belongs to java.lang unless I specify otherwise:

• Casting: ClassCastException

• Arrays: ArrayIndexOutOfBoundsException, NullPointerException

• Collections: NullPointerException, ClassCastException

• IO: java.io.IOException, java.io.FileNotFoundException, java.io.EOFException

• Seralization: java.io.ObjectStreamException

• Threads: InterruptedException, SecurityException, IllegalThreadStateException
