The keyword used in Java to ensure that a method locks a data object until it the method is complete is Group of answer choices synchronized allocated private concurrent

Java requires its method arguments to be sent in as values, not references. And what, precisely, does it entail?

The term "for construct" refers to a loop in computer programming that processes a list of items. As a direct consequence of this, it continues to operate for as long as there are objects to be processed. Which of these two interpretations of the statement is correct?

PLZ help with the following: True/False In java it is possible to throw an exception, catch it, then re-throw that same exception if it is desired GUIs are windowing interfaces that handle user input and output. An interface can contain defined constants as well as method headings or instead of method headings. When a recursive call is encountered, computation is temporarily suspended; all of the information needed to continue the computation is saved and the recursive call is evaluated. Can you have a static method in a nonstatic inner class?

Arithmetic Exception Arman has a shop where he provides stuff on rent. The whole payment system is computerised. A customer has to enter the item name, item type, cost, and the number of days they have taken the item for rent. The system then tells them the cost per day. But there is a problem with the machine that if the number of days entered is not an integer value then the system would crash. To handle this, Arman decided to upgrade the software and use exception handling in case the customer entered any invalid input it should display " Number of days x is invalid".Write a C++ program to find the item cost per day with the cost for n days given. The arithmetic exception has to be thrown if the n is less than or equal to zero.Strictly adhere to the Object-Oriented specifications given in the problem statement. All class names, member variable names, and function names should be the same as specified in the problem statement.The class Item has the following private data members....

What is the purpose of a constructor? It creates an array of data values associated with an object. It prints all of the information about our object. It returns all data members from an object back to the main method. It allows us to set our own default values when we create an object. in java
