The meaning of args in Java

In Java, "args" is an array used to store commands row parameters.

Detailed description:

When we run a Java program, we can pass parameters to the program. These arguments are passed to the main method (main) via the "args" array. Example:

<code class="java">public class Main {

    public static void main(String[] args) {
        // args 是一个 String 数组，存储命令行参数
    }
}</code>

Example:

Suppose we have a Java program named "ArgsDemo.java" that accepts two command line arguments. We can run it like this:

<code>java ArgsDemo arg1 arg2</code>

In this example, "arg1" and "arg2" will be stored in the "args" array:

<code class="java">public class ArgsDemo {

    public static void main(String[] args) {
        System.out.println("第一个参数：" + args[0]);
        System.out.println("第二个参数：" + args[1]);
    }
}</code>

Output:

<code>第一个参数：arg1
第二个参数：arg2</code>

Note:

• #The "args" array can contain any number of parameters.
• If no command line arguments are provided, the "args" array will be empty (length 0).
• "args" The element type of the array is String.
