- The maximum score of each semester

- The mininum score of each semester

Answer 1

JUST COPY PAST TO ECLIPSE (OR WHATEVER ELSE U USE)
I KNOW THIS WAS POSTED LIKE A WEEK AFTER BUT I DID THIS MOSTLY TO PRACTICE, HOPE IT WAS USEFULL


import java.util.Scanner;


public class Array {

public static void main(String[] args) {


//JUST GETTING SOME INPUT FIRST
System.out.println("E- = 1\nE = 2\nE+ = 3\nD- = 4\nD = 5\nD+ = 6\nC- = 7\nC = 8\nC+ = 9\nB- = 10\nB = 11\nB+ = 12\nA- = 13\nA = 14\nA+ = 15");

Scanner scannerCommand = new Scanner(System.in);
System.out.println("\nPlease entre the First Semester grade of Subject 1 (as a number): ");
int fSemfSub = scannerCommand.nextInt();

System.out.println("\nPlease entre the First Semester grade of Subject 2 (as a number): ");
int fSemsSub = scannerCommand.nextInt();

System.out.println("\nPlease entre the First Semester grade of Subject 3 (as a number): ");
int fSemtSub = scannerCommand.nextInt();

//

System.out.println("\nPlease entre the Second Semester grade of Subject 1 (as a number): ");
int sSemfSub = scannerCommand.nextInt();

System.out.println("\nPlease entre the Second Semester grade of Subject 2 (as a number): ");
int sSemsSub = scannerCommand.nextInt();

System.out.println("\nPlease entre the Second Semester grade of Subject 3 (as a number): ");
int sSemtSub = scannerCommand.nextInt();


//NOW ONTO THE ARRAYS...
int results[][] = {
{0,0,0},
{0,0,0}
};

//Setting the scores to the array...
results[0][0] = fSemfSub;
results[0][1] = fSemsSub;
results[0][2] = fSemtSub;

results[1][0] = sSemfSub;
results[1][1] = sSemsSub;
results[1][2] = sSemtSub;

//Calculating the average scores per semester
int faverageSemOne = (results[0][0] + results[0][1] + results[0][2]);
int faverageSemTwo = (results[1][0] + results[1][1] + results[1][2]);

//Couldn't get the calculation to work on one line so I made it 2
int averageSemOne = faverageSemOne / 3;
int averageSemTwo = faverageSemTwo / 3;

System.out.println("The average score for semester one was " + averageSemOne);
System.out.println("The average score for semester two was " + averageSemTwo);

//Calculating the max and min score in semester one
int min, max;
min = max = results[0][0];

if(results[0][1] <= min){
min = results[0][1];
}
else{
max = results[0][1];
}

if(results[0][2] <= min){
min = results[0][2];
}
else{
if(results[0][2] >= max){
max = results[0][2];
}
}
System.out.println("The maximum score for Semester one was: " + max);
System.out.println("The minimum score for Semester one was: " + min);

//Calculating max and min score for semester two
min = max = results[1][0];

if(results[1][1] <= min){
min = results[1][1];
}
else{
max = results[1][1];
}

if(results[1][2] <= min){
min = results[1][2];
}
else{
if(results[1][2] >= max){
max = results[1][2];
}
}
System.out.println("The maximum score for Semester two was: " + max);
System.out.println("The minimum score for Semester two was: " + min);
}

}

Oh and ull need to format it, i don't think it will be formatted from here.
