     PRACTICE PROBLEMS

     Part 1. Write Java programs that will input a single piece of information
             or two pieces of information, and then output the results of a
             calculation about that information.

     a.  Input an integer and output whether that number ends in a 7.
         Hint:  Either convert the integer to a string with the method
         String.valueOf, or use the % operator.

     b.  Input a string and output whether that string begins with a 
         'T' or a 't'.  Consider the case of a zero length string.<p>

     c.  Input an integer and output whether the integer is a prime number.

         Hint: If n is the integer, check all integers k from 2 to n - 1 to
               see if they are factors of n by using If (n % k == 0)


     Part 2. Write Java programs that will input a list of items terminated by
             a sentinel.  The program then prints output summarizing the list.

     a.  Input a list of positive integers.  Output the number of numbers that
         end in 7.

     b.  Input a list of strings.  Output whether any of the strings has a length
         of 4.

     c.  Input a list of hours worked and hourly wage.  Output the total amount 
         paid in wages.

     d.  Input a list of name, gender, and salary.  Output the name of the woman
         that earns the most money.

         Hint:  In addition to keeping track of the largest salary of all the women,
                you also need to keep trace of the name of the woman with the 
                largest salary.
