hours and minutes in words

Given a time in numbers we can convert it into words. For example :
5 : 00 ——  five o’clock
5 : 10 ——  ten minutes past five
5 : 15 ——  quarter past five
5 : 30 ——  half past five
5 : 40 ——  twenty minutes to six
5 : 45 ——  quarter to six
5 : 47 ——  thirteen minutes to six

Write a program which first inputs two integers, the first between 1 and 12 (both inclusive) and second between 0 and 59 (both inclusive) and then prints out the time they represent, in words.
Your program should follow the format of the examples above.

SAMPLE DATA :

1. INPUT :
TIME : 3,0
OUTPUT : 3 : 00 Three o’ clock
2. INPUT :
TIME : 7,29
OUTPUT : 7 : 29 Twenty nine minutes past seven
3. INPUT :
TIME : 6,34
OUTPUT : 6 : 34 Twenty six minutes to seven
4. INPUT :
TIME : 12,1
OUTPUT : 12 : 01 One minute past Twelve
5. INPUT :
TIME : 12,45
OUTPUT : 12 : 45 Quarter to One
6. INPUT :
TIME : 10,59
OUTPUT : 10 : 59 One minute to Eleven
7. INPUT :
TIME : 14,60
OUTPUT : Incorrect Input
Test your program for the data values given in the examples above and some random data.

 PROGRAM:-

          */
         if(h==12)
            a = words[1]; //storing 'one' when hour is 12
         else

            System.out.println(words[h]+" O' clock");

         else // condition for minutes between 31-59
            System.out.println(words[60-m]+" "+plu+" to "+a);
        } //end of outer if

        else
            System.out.println("Invalid Input !"); //printing error message for illegal input
    }
}

Enter Hours : 7
Enter Minutes : 16
Output : 7:16 —– Sixteen Minutes past Seven
