Java FAQ: How do I square a number in Java?
You can square a number in Java in at least two different ways:
Here's how to square a number by multiplying it by itself:
i = 2 int square = i * i
In that case, if you print the value of
square, it will be 4.
Here's how you call the Math.pow method to square a number:
i = 2 int square = Math.pow(i, 2)
In general I just multiply the number by itself to get the squared value, but the advantage of the Math.pow method is that you can easily get the cube of a number, like this:
i = 2 int square = Math.pow(i, 3)
Therefore, it's helpful to know both approaches.
