Create a new object

For constructors, you cannot do this as you do, because executing a constructor means creating a new object (to be precise, the process of creating an object involves allocating memory and constructing objects). So, the most similar examples of the above example are:

Import java.lang.reflect.*;PublicClass Constructor2 {PublicConstructor2 () {}PublicConstructor2 (int A,int b) {System.Out.println ("A =" + A +"B =" + b);}PublicStaticvoid main (String args[]) {try { Class cls = class.forname ( "Constructor2"); Class partypes[] = new class[2]; partypes[ 0] = Integer.type; Partypes[1] = Integer.type; Constructor ct = cls.getconstructor (partypes); Object arglist[] = new object[2]; arglist[ 0] = new Integer (37); Arglist[1] = new Integer (47); Object retobj = ct.newinstance (arglist); } catch (Throwable e) {System.err.println (e);}}       

Finds the appropriate constructor based on the specified parameter type and executes it to create a new object instance. It is valuable to use this method to create objects dynamically while the program is running, rather than creating objects at compile time.
