To get constructors of a class, you can write a code as follow.
Content of TestMain.java
package com.t4b.test;
import java.lang.reflect.Constructor;
import java.lang.reflect.InvocationTargetException;
public class TestMain {
public static void main(String[] args) {
new DBConnection();
ClassLoader classLoader = DBConnection.class.getClassLoader();
try {
Class aClass = classLoader.loadClass("com.t4b.test.DBConnection");
System.out.println("aClass.getName() = " + aClass.getName());
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
Constructor constructor;
try {
constructor = DBConnection.class.getConstructor();
DBConnection myObject = (DBConnection) constructor.newInstance();
myObject.dispaly();
System.out.println("#" + myObject.getClass().getName());
} catch (NoSuchMethodException | SecurityException e) {
e.printStackTrace();
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
}
}
