Too many 'if' statements?

Question

The following code does work how I need it to, but it\'s ugly, excessive or a number of other things. I\'ve looked at formulas and attempted to write a few solutions, but I

Answer 1

To be quite honest, everyone has their own style of code. I wouldn't have thought performance would be affected too much. If you understand this better than using a switch case version, then carry on using this.

You could nest the ifs , so potentially there would be a slight performance increase for your last if checks as it wouldn't have gone through as many if statements. But in your context of a basic java course it probably won't benefit.

else if(one == 3 && two == 3) { result = 3; }

So, instead of...

if(one == 0 && two == 0) { result = 0; }
else if(one == 0 && two == 1) { result = 0; }
else if(one == 0 && two == 2) { result = 1; }
else if(one == 0 && two == 3) { result = 2; }

You'd do...

if(one == 0) 
{ 
    if(two == 0) { result = 0; }
    else if(two == 1) { result = 0; }
    else if(two == 2) { result = 1; }
    else if(two == 3) { result = 2; }
}

And just reformat it as you'd prefer.

This doesn't make the code look better, but potentially speeds it up a little I believe.
