How to access the object of a class without using the class name from a static context in java?

The only possible solution is to get the stack trace of the current thread. Get the class name using an element in the stack trace. Pass it to the forName() method of the class named Class.

This returns a Class object and you can get an instance of this class using the newInstance() method.

Example

public class MyClass {
   String name = "Krishna";
   private int age = 25;
   public MyClass() {
      System.out.println("Object of the class MyClass");
      System.out.println("name: "+this.name);
      System.out.println("age: "+this.age);
   }
   public static void demoMethod() throws Exception {
      StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();
      StackTraceElement current = stackTrace[1];
      Class.forName(current.getClassName()).newInstance();
   }
   public static void main(String args[]) throws Exception {
      demoMethod();
   }
}

Output

Object of the class MyClass
name: Krishna
age: 25
