Can anyone explain this code? ( Mainly - {sum += myArr[x]; )

Question

int [ ] myArr = {6, 42, 3, 7};
int sum=0;
for(int x=0; x<myArr.length; x++) {
sum += myArr[x];
}
System.out.println(sum);

// 58

Answer 1

it simply sums up elements of that int array
//starting from index 0 to lengthOfArray-1 [in loop]
//sum+=x => sum=sum+x

Answer 2

welcome ,
statements execute from top to bottom available in block of main method()

Answer 3

Ohkk..Now I understand. But, tell me one last thing- The execution process of the statements .

Means which statement will be executed first, then second and so on..

Thanks for answering.
