Write a program that calculate percentage marks of the student if marks of 6 subjects are given(using else-if)



import java.util.Scanner;

class Calculator

int division(int num1,int num2)
{
if(num2!=0)
{
return (num1 / num2);
}
else
{
System.out.println(" Denominator never be 'zero' !!!");
    return 0;
}
}
}

class CalculatorDemo
{
public static void main(String args[])
{
int ch,ans,num1,num2;
Calculator c1=new Calculator();
