Implement and test a generic binary search. Note that your test program must use at least 2 types of data to prove that bsearch is generic.

Templating means that instead of passing a parameter such as Integer you pass a parameter T. (T is a type variable and can be named anything). This means that you can call bsearch with different types of objects.

Pseudo Code Example:

Bsearch(String) Bsearch(Integer)

This means you do not have to write 2 separate bsearch methods, one for String and one for Integer.

The heart of how this is accomplished is the Comparable interface. If a class implements Comparable, it defines less than, greater than and equals. Also, by making the type variable you can call with any object that implements Comparable.

Example Code:

public class Searches

{

public static int bsearch(T[] a, int first, int last, T key)

{

called in main as:

result = Searches.bsearch(IntegerArray,0, 10, key);

result = Searchesbsearch(StringArray,0,10,key);
