How do you sort two digits in java?

Answer 1

If all you're dealing with is two digits, there are multiple ways of sorting them.

1. It can be done manually with a simple if comparison:

if (a < b) {

// a is smaller

} else if (a > b) {

// a is larger

} else {

// a equals b

}

2. You can use the Math class:

Math.max(a, b); // returns the larger of the two numbers

Math.min(a, b); // returns the smaller of the two numbers

3. If added to a Collection, you can sort it. (This will work for any number of items added to the Collection, and uses the natural ordering of the items).

ArrayList numberList = new ArrayList();

numberList.add(a);

numberList.add(b);

numberList = Collections.sort(numberList);
