Issue with using switch in Java

Question

I can\'t figure out why it\'s always returning the value of arg1. I\'m building a weight converter.

public double convert(double arg1,int arg2,int arg3) {
    //         


        

Answer 1

Other than using break, using return statements does the trick as well as it also prevents falling through cases.

case 2: switch(arg3) { // if ounce
    case 0: return (arg1 * milligram) / milligram;
