Good Programming Tactics


#### Avoid IF statements

<<
void increaseTimeCount( int value, int type ) {
    int[] a = ... ;
    int minIndex;
    int maxIndex;
    int avgIndex;
    if (type == TYPE_A) {
	minIndex = 0;
	maxIndex = 1;
	avgIndex = 2;
    }
    else if (type == TYPE_B) {
	minIndex = 3;
	maxIndex = 4;
	avgIndex = 5;
    }
    ...
    a[minIndex] = Math.min(a[minIndex],value);
    ...
}
>>

Should make type an offset (0 or 3):

<<
void increaseTimeCount( int type ) {                                
    static final MIN_INDEX = 0;
    static final MAX_INDEX = 1;
    static final AVG_INDEX = 2;
    int[] a = ... ;
    ...
    a[MIN_INDEX+type] = Math.min(a[MIN_INDEX+type],value);
    ...
