Thread: Odd and Even Numbers Logics in FOR and IF Loop methods

Hey all

This comment very useful for beginners

I have shown the Odd and Even Numbers Logics Programs in FOR and IF Loop Condition, please Click here

Hi,

I saw your program. While we loop the numbers why can't you have a single IF and ELse condition so that in If's part it would be even number . If the quotient is not zero its going to go into else part and it would increase the counter for Odd.

I am too a begineer in Java programming. If i am wrong please suggest me.

Thanks,
DAK.

You are right Dak.

I think the loop can be improved:

int o = 0;
int e = 0;
for (int i = 1; i <= n; i++) {
    if (i % 2 == 0) {
        even[e++] = i;
        if (e == 2) {
            sb.append(even[0]).append(" ").append(even[1]).append(", ");
            e = 0;
        }
    }
    else {
        odd[o++] = i;
        if (o == 2) {
            sb.append(odd[0]).append(" ").append(odd[1]).append(", ");
            o = 0;
        }
    }
}
