Yes you can do this with the help of Reflection.

public class Hello {
  public void display() {
    System.out.println("Hello World");
  }
  public static void main(String args[]) throws Exception {
    Class c1 = Class.forName("Hello"); // throws ClassNotFoundException Object obj1 =       c1.newInstance( ); // throws InstantiationException and // IllegalAccessException
    Hello h1 = (Hello) obj1;
    h1.display();
  }
}

1) your could use the jdbc's way

Class.forName("YOURCLASSNAME").newInstance()

2) You can use clone method to create a copy of object without new operator.

Example for String class

String sample = new String();

Now we are not going to use new operator and we will create a new object

String sampleClone = sample.clone();
