BJP3 Exercise 6.18: plusScores

Language/Type: Java file processing Scanner
Author: Roy McElmurry (on 2013/04/01)

Write a static method named plusScores that accepts as a parameter a Scanner containing a series of lines that represent student records. Each student record takes up two lines of input. The first line has the student's name and the second line has a series of plus and minus characters. Below is a sample input:

Kane, Erica
--+-+
Chandler, Adam
++-+
Martin, Jake
+++++++
Dillon, Amanda
++-++-+-

The number of plus/minus characters will vary, but you may assume that at least one such character appears and that no other characters appear on the second line of each pair. For each student you should produce a line of output withthe student's name followed by a colon followed by the percent of plus characters. For example, if the input above is stored in a Scanner called input, the call of plusScores(input); should produce the following output:

Kane, Erica: 40.0% plus
Chandler, Adam: 75.0% plus
Martin, Jake: 100.0% plus
Dillon, Amanda: 62.5% plus
