Javascript multi-value array

Question

This may seem like a rather odd/dumb question but I would like to replicate the following JavaScript array in Java.

var myArray = new Array();          
myArray[0] = ['Time', 'Temperature'];
myArray[1] = ['00:02', 20];
myArray[2] = ['01:30', 21];

What is strange to me is that there are multiple values in a single array location so I don't know what is going on; is this a two-dimensional array?

It's an array of arrays. That's kind-of like a two-dimensional array, but it's not stored the way a 2D array would be stored in C or C++. — Pointy

In Java:

Object[][] myArray = {
    new Object[]{"Time", "Temperature"},
    new Object[]{"00:02", 20},
    new Object[]{"01:30", 21}
};

You can do it in this manner:

String[][] myArray = {
    {"Time", "Temperature"},
    {"00:02", "20"},
    {"01:30", "21"}
};

Although I don't recommend this since you're losing a lot of type information and using String for everything doesn't scale well and isn't very maintainable. It is probably better to create a TemperatureReading class and have a list of TemperatureReading instances.
