The declaration of the empty constructor prevents the automatic generation of a default constructor.

Whenever a class or struct is created, its constructor is called. A class or struct may have multiple constructors that take different arguments. Constructors enable the programmer to set default values, limit instantiation, and write code that is flexible and easy to read.

A class can have any number of static initialization blocks, this block is called "constructor block" and will be executed when the class is instantiated. ... There is a limitation of JVM that a static initializer block should not exceed 64K.

A constructor that takes no parameters is called a default constructor. Default constructors are invoked whenever an object is instantiated by using the new operator and no arguments are provided to new. Instance constructors are used to create and initialize any instance member variables when you use the new expression to create an object of a class. To initialize a static class, or static variables in a non-static class, you must define a static constructor. It enables the programmer to set default values, limit instantiation, and write code that is flexible and easy to read. read less
