Please explain this program

Question

public class Program {
public static void main(String[] args) {
int [ ] myArr = {6, 42, 3, 7};
int sum=0;
for(int x=0; x<myArr.length; x++) {
sum += myArr[x];
}
System.out.println(sum);
}
}

Answer 1

Here, myArr has some elements and with for loop addition each element to others and Store it to sum variable..
myArr.length specific how array's length here is 4
After starting for loop x initialised to 0 and also check for x <4.
As condition true loop run and
Sum+=myarr[x] treat like sum=sum+myArr[0]
Then sum=6
After that it's goes for x++ and loop run untill X value will be 4..
