How do you print output in Java?

In Java, you can use the `System.out.println()` method to print output. This method sends the specified content to the console.

Here is a simple example demonstrating how to use Java to print output.

public class PrintOutputExample {
    public static void main(String[] args) {
        // 打印字符串
        System.out.println("Hello, World!");
        // 打印整数
        int num = 10;
        System.out.println("The number is: " + num);
        // 打印浮点数
        double pi = 3.14159;
        System.out.println("The value of pi is: " + pi);
    }
}

Running the above code will display the following output in the console.

Hello, World!
The number is: 10
The value of pi is: 3.14159
