如何从以字符串形式给出的 java 代码解析包？

Question

I have a String in a simple Java program:

public class Test {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        int input = scanner.nextInt();

        System.out.println("Your input was: " + input);
    }
}

And I need to parse the package for Scanner :

java.util.Scanner
and any other matching packages

I don't want code as an answer, rather an explanation how to do it, ideally without an IDE. I have to be able to code with the basic Windows Editor without automatic package importing. A simple java program needs to make these imports for me.

Hope you guys can help me.

Answer 1

// Get package name and print it

Package pack = YourClassName.getClass().getPackage();
String packageName = pack.getName();
System.out.println("Package = " + packageName);
