Original address: Java programming trick (1) - Method returns two objects  Stars-One's groceries title is a false proposition, and we all know that, in Java's grammar, the method is either to return one object or not to return to one or more objects, and we need to return to two or more objects, and what to do? This method you can understand in detail is simply to create a new class, and then there's a few new words in the class that will be available

The subject is a pseudo-promotion, and we all know by Java that the method is either to return to one or not.

What do we do when there are two or more objects we need to return to?

You can understand this in detail. It's just a new class, and then there's just a few more fields in the class.

But if we're in a lot of trouble with new classes each time, is there a more convenient use?

Of course there are. We can use the Pair class.

<code>Pair</code>和<code>MutableTriple</code>都是lang3包中提供的，所以要使用，得先加入依赖

Or the example above. We can use the Pair to fix it.

As you can see, we don't need to declare a new category to achieve what we need to return to two targets.

If it's three objects, it's just the same, it's just the Mutable Triple, and it's a generic receiver.

What, you asked me if I had a Pair class of four?

Because there are more than three, the government has recommended a new class to do it!

Finally, in Kotlin, the default has already been realized in both of these categories.
