I think you are creating an array of wrong bounds- instead of int [][] list=new int [2][mo] there should be int [][] list=new int [mo][2]; ,because for every module you have marks of first and second assignment, am I right?

You can try this way
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner Sc = new Scanner(System.in);
int mo, i, j, a;
System.out.println(" how many modules you have in this semester ?");
mo = Sc.nextInt();
// creat the Array
int[] tab = new int[mo];
for (a = 0; a < mo; a++) {
System.out.println(" Enter the module name : " + (a + 1));
tab[a] = Sc.nextInt();
}
int[][] list = new int[2][mo];
for (i = 0; i < 2; i++) {
for (j = 0; j < mo; j++) {
System.out.println(" Enter the marks of the " +
(i + 1) + " Assignment : " + (i + 1) + "," + j);
list[i][j] = Sc.nextInt();
}
}
}
}

How to take array input from command line in Java ? Scanner Example
April 2, 2025 - Now, let's see the output of this program to understand how to take array as input from command line in Java: Output Please enter length of String array 3 Please enter array elements Java C++ Ruby The String array input from user is : [Java, C++, Ruby] Please enter number of rows and columns of 2D array 2 3 Please enter array elements row by row 1 2 3 4 5 6 The 2d int array input from user is : [[1, 2, 3], [4, 5, 6]] You can see that we have successfully taken array input from the user, both String and integer array, and both one and a two-dimensional array. Don't forget to close the Scanner once you have done to prevent resource leaks in Java, you can also see these Java programming courses to learn more about why you should close readers and stream once you are done using them.
