Java provides a main method that invokes another class in the main method of a class

In Java, there are two ways in which a class can invoke another class by instantiating the class, invoking the method of instantiating the object, and invoking it using the Java mapping mechanism. The first method is no longer explained, and the second method uses the following:

public class Run {

public static void Main (string[] args) {
String str = args[0] + "Hello World";
System.out.println (str);
}

}

Import Java.lang.reflect.Method;

public class Jobrun {
public static void Main (string[] args) {
String idstr = "YAya";
try {
Method method = Run.class.getMethod ("main", String[].class);
Method.invoke (Run.class.newInstance (), New object[]{New String[]{idstr});
catch (Exception e) {
E.printstacktrace ();
}

}
}
