Programmer{■} ➝ Java automatically provides a default constructor, so all classes have a constructor, whether one is specifically defined or not. https://www.sololearn.com/learn/Java/2157/

When we create the object then the constructor will be automatically called by the JVM. If you don't define any constructor, the compiler automatically creates a default constructor and assign default values for all your variables in the class. NOTE: If you define at least one constructor, the default constructor is not generated.

If you do not create a constructor, a default constructor which does nothing will be generated by your compiler.
