No, we cannot make constructor static in Java and the reason why cannot we make constructor static because static context belongs to the class, not the object. Therefore, onstructors are invoked only when an object is created, there is no sense to make t
The above example would be unnecessary because Java automatically creates a no-argument constructor for all classes that don’t have other constructors. Typically, if you define a constructor in a class, it is so that you can pass data to the object through parameters. This is an example of...
Yes, a static class can have static constructor, and the use of this constructor is initialization of static member. Suppose you are accessing the first EmployeeName field then constructor get called this time, after that it will not get called, even if you will access same type member. Can...

a particular method’s objective, and mocking/stubbing them out of a unit test wouldn’t make sense. They are part of the implementation, and should be tested as such. The second type is static methods used in place of constructors as Joshua Bloch showed in his book“Effective Java.”...

Fine-grained specification of time-out delays, because a large portion of the classes found in the java.util.concurrent packages exhibit support for time-out delays. An example is an executor that interrupts tasks execution if the tasks cannot be completed within a bounded timespan. Rich synchr...
