In a Java Program, when an object gets created then the static block is called, then the constructor gets called.

The source code to call the static block using an anonymous object is given below. The given program is compiled and executed successfully.

class Sample {
  static {
    System.out.println("Static block called");
  }

  Sample() {
    System.out.println("Constructor called");
  }

}

public class Main {
  public static void main(String[] args) {
    new Sample();
  }
}

Output

Static block called
Constructor called

Explanation

In the above program, we created two classes Sample and Main. The Sample class contains a Static Block and a constructor.

The Main class contains a method main(). The main() method is the entry point for the program, here we created an anonymous object of the Sample class and called static block and constructor of the class.
