Answer to Question #262390 in Java | JSP | JSF for dee

Question

 Create a program with three methods/functions, The first one takes in n which is the size of an array then creates and populate the array with student names, the second method takes in n which is the size of an array then creates and populate n by 3 array with student marks(The three marks are for test 1 - 3) and finally a method that takes in the two arrays, calculates the final mark of all test and print out the results as indicated below: The first method should return and array of names and the second should return an array all test marks(i.e. 2d array with 3 columns). The third method in addition should also return an array for all the final marks

Answer 1

package marksstudent;


import java.util.Scanner;




public class MarksStudent {


   static String[] populate(int n){
       String [] names = new String[n];
       System.out.println("Enter the names of the students\n");
       Scanner scan = new Scanner(System.in);
       for(int i=0; i<n; i++){
           names[i] = scan.nextLine();
       }
       return names;
   }
   static int [][]  marks(int n){
       int [][] test = new int[n][3];
        System.out.println("Enter the marks of the students\n");
       Scanner scan = new Scanner(System.in);
       for(int i=0; i<n; i++){
           for(int j=0; j<3; j++){
               test[i][j] = scan.nextInt();
           }
       }
       return test;
   }
   
    static int [] display(int n){
       String [] names= populate(n);
       int [] [] tests  = marks(n);
       int [] results = new int [n];
       int sum = 0;
       System.out.printf("Name Test01  Test02  Test03  Final ");
       System.out.printf("-------------------------------------");
       for(int i =0; i<n; i++){
           System.out.printf("%s\t", names[i]);
           for(int j=0; j<3; j++){
               System.out.printf("%d\t", tests[i][j]);
               sum += tests[i][j];
           }
           System.out.printf("\n");
           results[i] = sum / 3;
       }
       return results;
    }
    public static void main(String[] args) {
       
        
    }
