Question

write the definition of the class Tests such that an object of this class can store a student's 1st name, last name, 5 test scores, average tests score, and grade. (use array to store test scores). Add constructors and methods to manipulate data stored in an object. Among other things, your class must contain methods to calculate grades, and modify, individualing test scores. The method toString must return test data (including student's name, 5 test scores, average, and grade) as a string.

now I need to write a program to calculate students average test scores and the grade. you may assume the following input data: Jack Johnson 85 83 77 91 76 lisa Aniston 80 90 95 93 48 andy cooper 78 81 11 90 73 Ravi Gupta 92 83 30 69 87 Bonny Blair 23 45 96 38 59 Danny Clark 60 85 45 39 67 Samatha Kennedy 77 31 52 74 83 Robin Bronson 93 94 89 77 97 SheilaSunny 79 85 28 93 82

Kiran Smith 85 72 49 75 63 Use an array of objects of the class Tests(designed in part a) to score each student's data. The program should output data as close as possible to the following form: first_name Last name test1 test2 test3 test4 test5 average Grade jack johnson 85.00 83.00 77.00 91.00 77.00 82.40 B and so on with the rest of studes

class average = 70.94

this is from the Java programming from prolem analysis to program design BY: D.S. Malik

So im trying to get this in JAVA code Please.

thank you so much for anything
