How do you represent powers in Java?

In Java, you can use the pow method from the Math class to calculate the power of a number.

The grammar is as follows:

double result = Math.pow(base, exponent);

In this case, the base refers to the number being raised to a power, the exponent is the power to which the base is raised, and the result is the outcome of the calculation.

For example, to calculate 2 raised to the power of 3, you can use the following code:

double result = Math.pow(2, 3);
System.out.println(result); // 输出 8.0

It is important to note that the Math.pow method returns a result of type double. If you want to obtain an integer result, you can use type conversion, or use the Math.round method to round the result.
