We can create an object of a class without using ‘new’ keyword with the help of the forName() method.
- forName() is a static method of java.lang.Class package that loads the byte code (.class file) of a class whose name is given as argument.
Example :
class MyClass
{
public void message()
{
System.out.println(“ProgrammingPrashn.com”);
}
}
class Main
{
public static void main(String args[]) throws Exception
{
Class c = Class.forName(“MyClass”); // [1]
Object obj = c.newInstance( ); // [2]
MyClass m = (MyClass) obj; // [3]
m.message();
}
}
Explanation :
[1] : forName() method is called, it search and load the .class file of ‘MyClass’. It may throw ClassNotFoundException.
[2] : newInstance()method returns an object of the Object class.
[3] : Explicitly type-cast object obj to MyClass object m.
Output :
ProgrammingPrashn.com
