Working with the C++ language, discuss the different data types available. What are some of the differences, if any, between data types in C++ versus Java? Name three different data types and provide real-world examples of how you would use them within an application. What is logic programm...
Under certain conditions the plan shown when using EXPLAIN PLAN can be different from the plan shown using V$SQL_PLAN. For example, when the SQL statement contains bind variables the plan shown from using EXPLAIN PLAN ignores the bind variable values while the plan shown in V$SQL_PLAN takes ...
• In object-oriented programming, data integrity and data security is high as it focuses on the data and its protection from manipulation by different parts of the program. As a result, object-oriented programs are less error-prone, more reliable and secure. ...
an interface or a convention needs to be defined, and then different scenarios can be implemented. The caller does not need to pay too much attention to specific implementation details when using it. In Java, SPI embodies the idea of interface-oriented programming and satisfies the principle of...
QSM-01073 materialized view, string, has a join not found in query Cause: Query rewrite may not be possible if the materialized view has some joins that query does not have Action: No action required. QSM-01074 materialized view, string, and query have different no of joins between tables...

These sound like different things to me: one needs to propagate errors (apparently? see below), and one doesn't. I've argued that if an interface method returns an error, you have to check it in the general/library case, which everyone has tacitly accepted by not arguing against it—ple...
An interface is a way of describing what classes should do, without specifying how they should do it. A class can implement more than one interface. In Java, an interface is not a class but a set of requirements for the class that we want to conform to t
Give an example of a programming situation where you could use multiple objects of different classes. (a) What is a constructor in java? Explain. (b) Give an example. What makes a class abstract? Explain the answer with full details. Describe the relationship between classes and objects. ...
