Write a program to read test scores, process scores, and display a final report

Question

Write a program to read test scores, process scores, and display a final report or save the report into a text file. A report is generated for a class of 4 students Note: It is not required to write a Java class with instance/static members in this project. Write in method main. A test score is an integer from 0 to 100 If an average is 90 or greater, the letter grade A is assigned Otherwise, if an average is 80 or greater, the letter grade B is assigned Otherwise, if an average is 70 or greater, the letter grade C is assigned Otherwise, the letter grade F is assigned Users can process the scores and display a report like this, save the report into a file, or quit. Test1 Test 2 Average Grade 090 082 039 089 059 080 100 092 074.5 081.0 069.5 090.5

Explanation / Answer

import java.util.Scanner;

import java.io.*;

public class report {

public static void main(String[] args) throws IOException{

Scanner console=new Scanner(System.in);

int ts[]=new int[4]; //test score array

int ps[]=new int[4]; //process score array

for(int i=0;i<4;i++)

{

System.out.printf("Enter Test Score and Process Score of Student %d ::",(i+1));

ts[i]=console.nextInt();

ps[i]=console.nextInt();

}

float av[]=new float[4]; //average score array

char grade[]=new char[4]; //grades array

for(int i=0;i<4;i++)

{

av[i]=(float)(ts[i]+ps[i])/2;

if(av[i]>=90)

grade[i]='A';

else if(av[i]>=80 && av[i]<90)

grade[i]='B';

else if(av[i]>=70 && av[i]<90)

grade[i]='C';

else

grade[i]='F';

}

FileWriter fw = new FileWriter("report.txt");

PrintWriter fout = new PrintWriter(fw);

String str = String.format("Test 1 Test 2 Average Grade ");

String str2 = String.format(" ------ ------ ------ ------ ");

fout.println(str);

fout.println(str2);

for(int i=0;i<4;i++)

{

String s=String.format("%d %d %f %c ",ts[i],ps[i],av[i],grade[i]);

fout.println(s);

}

fout.close();

}

}
