The exceptions thrown by API methods like NumberFormatException ,IllegalArgumentException,ArrayIndexOutOfBoundsException are programatically thrown.

What do you mean by "programmatically thrown" and "JVM thrown"?

You can always throw anything which is throwable from your code. Throwable is at the top of the hierachy. So in this way you can throw any exception of error you want from your code and also catch the same. But it is recomonded that you only throw exception or error which is more relevant and easy to understand during debuging.

Two of them are. ArrayIndexOutOfBoundsException is thrown by the JVM, though, whenever you try to access an array index that doesn't exist.

You can throw any exception programmatically. But some are only thrown that way - meaning that somewhere in the source code (either yours or an API) there's a statement that says "throw new ...".
