  • Ans. 

    The purpose of a default constructor is to initialize the object's instance variables with default values.

    • A default constructor is automatically provided by the compiler if no constructor is defined in the class.

    • It is used to create an object of the class with default values for its instance variables.

  • Ans. 

    Constructors are special methods used to initialize objects, while methods are regular functions that perform specific tasks.

    • Constructors have the same name as the class, while methods have unique names.

    • Constructors are called automatically when an object is created, while methods need to be called explicitly.

    • The main method is the entry point of a Java program, and it needs to be called by the JVM to start the execution.

    • If the main method were not static, we would need to create an object of the...
