idea—Set main method parameters

One, write the program

public class Hel {
    public static void main(String[] args) {
        String s = args[0];                     //接收第一个参数
        int i = Integer.parseInt(args[1]);      //接收第二个参数：因为args默认是String类型
        System.out.println(s+i);
    }
}

Two, enter the parameters of the main method

1, the first step

2, the second step,

just run it
