In some cases our code may throw more than one exception. 
In such case we can specify two or more catch clauses, each catch handling 
different type of exception. When an exception is thrown jvm checks each 
catch statement in order and the first one which matches the type of 
exception is execution and remaining catch blocks are skipped.
Try with multiple catch blocks is highly recommended in java.
If try with multiple catch blocks are present the order of catch blocks is 
very important and the order should be from child to parent.
