چند نکته در مورد Constructor در جاوا

• Constructor is same as method without return type. It's job only an  initialization the instance variables with the default values.
• Explicitly we can not call the constructor. JVM has to call the constructor.
• Constructors name should be same as the class name.
• The constructor can be created when the we create the object.
• The constructor can be call only once per object.
• Job of construction: set default value to class variables.
• If we pass argument to constructor it is known as parameter constructor
• We can create our java class without any constructor but a java class without constructor is not possible, because the java compiler adds the default constructor if a user has not mentioned any constructor
• Note**: Java compiler adds default constructor nooooot JVM
