Write a java program to get student marks for each subject and display sum and average for the given Marks by using method and creat object
```java
import java.util.Scanner;
class StudentMarks {
int[] marks;
public StudentMarks(int numSubjects) {
marks = new int[numSubjects];
}
public void setMarks(int index, int mark) {
marks[index] = mark;
}
public int getSum() {
int sum = 0;
for(int mark : marks) {
sum += mark;
}
return sum;
}
public double getAverage() {
return getSum() / marks.length;
}
}
public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("Enter the number of subjects: ");
int numSubjects = scanner.nextInt();
StudentMarks student = new StudentMarks(numSubjects);
for(int i=0; i<numSubjects; i++) {
System.out.println("Enter marks for subject " + (i+1) + ": ");
int mark = scanner.nextInt();
student.setMarks(i, mark);
}
System.out.println("Sum of marks: " + student.getSum());
System.out.println("Average of marks: " + student.getAverage());
}
}
```
This program takes input for the number of subjects, then prompts the user to enter marks for each subject. It creates a `StudentMarks` object and uses its methods to set marks, calculate sum and average of marks, and then displays the results.
