PROGRAM DESCRIPTION This is a simple program that allows the students to enter their personal information. This program also calculates the average of his/her grade by entering their midterm and final grade.

Page


ALGORITHM 1. Ask for student information:

a. Student name

b. Year & Section

c. Program

d. Student Number

e. Department

f. Midterm Grade

g. Final Grade

2. Calculate the average of his/her grade

3. Display the result:

a. Student name

b. Year & Section

c. Program

d. Student Number

e. Department

f. Midterm Grade

g. Final Grade

h. Average

LEARNING OUTCOMES In this program, I learned on how to process the input and output in Java Programming Language. I conclude that Java has a similarity with C++. Like C++, Java has primitive types such as int, float, etc. But unlike C++, the size of each primitive type is the same regardless of the platform. Although Java uses the same keywords as C++ for access control: private, public, and protected, the interpretation of these keywords is significantly different between Java and C++.
