Papillary thyroid cancer (also sometimes called papillary thyroid carcinoma) is the most common type of thyroid cancer. You may have even heard your doctor talk about metastatic papillary thyroid cancer (metastatic means that it has spread beyond your thyroid gland).
Classes can have special methods called constructors. A constructor is a method that is automatically called when an object is created. Constructors are used to perform operations at the time an object is created. Constructors typically initialize instance fields and perform other object initialization tasks.
So basically an object is created from a class. In Java, the new key word is used to create new objects. There are three steps when creating an object from a class: Declaration: A variable declaration with a variable name with an object type. Instantiation: The 'new' key word is used to create the object. Initialization: The 'new' keyword is followed by a call to a constructor.
