Answer:
false true
Explanation:
In the code snippet, two string objects are created in java with the value Java.
The print method first checks the condition s1==s2 and outputs false, This is so because the operator == which is used for equality in other primitive data types like ints cannot be applied to the String data type. In the second part of the print function, the equals function s1.equals(s2) is used and it prints true since the two string are equal
Answer:
The appropriate answer is "Distributed system".
Explanation:
- Whenever used by linking several autonomous computers as a single system, considered as distributed system. It could be consist of several kinds of mainframes, processors as well as stationary machines, it can be programmed.
- A distributed machine has massive program modules, which operate as a single device on many machines.
Answer:
C. receiving data.
Explanation:
An information system interacts with its environment by receiving data in its raw forms and information in a usable format.
Information system can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.
Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information systems in order to perform their duties, functions or tasks and to manage their operations effectively. For example, all organizations make use of information systems for supply chain management, process financial accounts, manage their workforce, and as a marketing channels to reach their customers or potential customers.
Additionally, an information system comprises of five (5) main components;
1. Hardware.
2. Software.
3. Database.
4. Human resources.
5. Telecommunications.
<em>Hence, the information system relies on the data it receives from its environment, processes this data into formats that are usable by the end users. </em>
Answer:
a. Partly True
b. True
Explanation:
(a) "new" keyword or syntax is used for the constructors while working in Perl and Moose object system for Perl.
For Visual Basics .Net, keyword "New" is used
For Python, "___new___" is used which allocates memory for instance and receives class as an argument.
For Objective-C, "alloc" and "init" are used for constructor method. "alloc" allocates memory for the instance and "init" handles the bulk of initializing the instance. Whereas, the "new" keyword calls both "alloc" and "init" for class instance.
(b) A constructor does not return any value because it is called by the memory allocation and object initialization code in the runtime and not directly by your code.
