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

You can create matrix which contains results

int[][] results = {{0, 0, 1, 2}, {0, 0, 2, 1},{2, 1, 3, 3},{2, 1, 3, 3}};

When you want to get value you will use

public int fightMath(int one, int two) {
  return this.results[one][two]; 
}

Answer 2

A good point would be to define the rules as text, you can easier derive the correct formula then. This is extracted from laalto's nice array representation:

{ 0, 0, 1, 2 },
{ 0, 0, 2, 1 },
{ 2, 1, 3, 3 },
{ 1, 2, 3, 3 }

And here we go with some general comments, but you should describe them in rule terms:

if(one<2) // left half
{
    if(two<2) // upper left half
    {
        result = 0; //neither hits
    }
    else // lower left half
    {
        result = 1+(one+two)%2; //p2 hits if sum is even
    }
}
else // right half
{
    if(two<2) // upper right half
    {
        result = 1+(one+two+1)%2; //p1 hits if sum is even
    }
    else // lower right half
    {
        return 3; //both hit
    }
}

You could of course crunch this down to less code, but it is generally a good idea to understand what you code rather than finding a compact solution.

if((one<2)&&(two<2)) result = 0; //top left
else if((one>1)&&(two>1)) result = 3; //bottom right
else result = 1+(one+two+((one>1)?1:0))%2; //no idea what that means

Some explanation on the complicated p1/p2 hits would be great, looks interesting!
