Zeek_82_NestedTryBlock.java

 

/*

--> In Java, using a try block inside another try block is permitted.

--> It is called as nested try block.

For example, the inner try block can be used to handle ArrayIndexOutOfBoundsException while

             the outer try block can handle the ArithemeticException (division by zero).

--> Write a code in which the inner block handles ArithemeticException and outerblock handles

ArrayIndexOutOfBoundsException
