First, Let us understand the concept of construcotrs. The constructors are used to construct objects. This is the Only way to create object. If we did not write any constructor in our class, the compliler itself creates a dummy default constructor, which do not have parameters and code. When this dummy default constructor is executed the JVM initializes the instance variable by their default values.
