How do you represent exponents in Java?

In Java, you can use the Math.pow() method to represent an exponent. The method Math.pow(x, y) takes two parameters, x and y, and returns the result of x raised to the power of y. For example, to calculate 2 raised to the power of 3, you can use Math.pow(2, 3), which will result in 8.

Here is an example code:

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

Please note that the Math.pow() method returns a result of type double. If you need to convert the result to an integer type, you can use type casting as shown below:

int result = (int) Math.pow(2, 3);
System.out.println(result); // 输出8
