Finding kth element is more efficient in a doubly-linked list when compared to a singly-linked list
Explanation:
Assuming that both lists have firs_t and last_ pointers.
For a singly-linked list ; when locating a kth element, you have iterate through a number of k-1 elements which means that locating an element will be done only in one ( 1 ) direction
For a Doubly-linked list : To locate the Kth element can be done from two ( directions ) i.e. if the Kth element can found either by traversing the number of elements before it or after it . This makes finding the Kth element faster because the shortest route can be taken.

Answer:
You can have many catch blocks to handle different types of exceptions.
Explanation:
In programming, catch and try are blocks of codes that are written to handle errors. While the try block of code will allow for the definition of code blocks which are tested for errors, the catch block of code allows the programmer to define the block of code to be executed if an error occurs in the try block.... somewhat like the if....else statements. since there could be different error handling scenarios,one can have as many catch blocks for different error exceptions
