The newInstance() method of Class class and Constructor class is used to create a new instance of the class.
The newInstance() method of Class class can invoke zero-argument constructor whereas newInstance() method of Constructor class can invoke any number of arguments. So Constructor class is preferred over Class class.
public T newInstance() throws InstantiationException,IllegalAccessException
Here T is the generic version. You can think it like Object class. You will learn about generics later.
Let's see the simple example to use newInstance() method.
class Simple{
void message(){System.out.println("Hello Java");}
}
class Test{
public static void main(String args[]){
try{
Class c=Class.forName("Simple");
Simple s=(Simple)c.newInstance();
s.message();
}catch(Exception e){System.out.println(e);}
}
}
