Date: 2012may2 Language: Java Q. Java: What's a good way to manage a group of boolean options that I am passing to a method in Java? A. Use a BitSet. Make some names of the bits:

static final int OPTION_A = 0; // The first bit represents option A (whatever that is) static final int OPTION_B = 1; static final int OPTION_C = 2; static final int OPTION_D = 3;

Declare your function as so:

myfunction(BitSet options) { if (options.get(OPTION_B)) { // Do option B things } }

And call it this way:

BitSet myoptions = new BitSet(); myoptions.set(OPTION_A); myoptions.set(OPTION_C); myfunction(myoptions);

The ugly alternative using booleans:

myfunction(boolean option_a, boolean option_b, boolean option_c, boolean option_d) { if (option_b) { // Do option B things } }
