How does the java return tuple work?

Sometimes you want to return multiple values from a function. How is this normally done in Java? One option is to use an array, like this Python snippet that returns a list or tuple:

value, success = read_unreliably()
if success:
    print value
Another option would be to return a hash/dict, like this JavaScript example:
var result = readUnreliably()
if (result.success) {
    alert(value);
}

One more would be to create a custom object just for this purpose, like this Java example:

ReadUnreliablyResult result = readUnreliably()
if (result.getSuccess()) {
    System.out.println(result.getValue());
}

Of course you can also just use some global variables to store what you need instead of passing things around, but let's just say that's not an option.
