Answer:
d. public myClass( ) {. . .}
Explanation:
A constructor is a special method that is called when an object of a class is created. It is also used to initialize the instance variables of the given class. A class may have one or more constructors provided that these constructors have different signatures. A class that does not have a constructor explicitly defined has a default parameterless constructor.
Having said these about a constructor, a few other things are worth to be noted by a constructor.
i. In Java, a constructor has the same name as the name of its class.
For example, in the given class <em>myClass</em>, the constructor(s) should also have the name <em>myClass</em>.
ii. A constructor does not have a return value. It is therefore wrong to write a constructor like this:
<em>public void myClass(){...}</em>
This makes option a incorrect.
iii. When a constructor with parameters is defined, the default parameterless constructor is overridden. This might break the code if some other parts of the program depend on this constructor. So it is advisable to always explicitly write the default parameterless constructor.
This makes option d a correct option.
Other options b and c may also be correct but there is no additional information in the question to help establish or justify that.
Here is your answer:
The physical parts or components of a computer system is called "computer hardware." Computer hardware is what stores most of your computers applications that help it run more fluently for example the computers speakers are part of it's hardware since how it's used to help the person hear the computer and it helps the computer run smoothly.
Hope this helps!

Answer:
Correct answer is option B (The reason for using supertypes is to minimize the number of nulls and to minimize the likelihood of redundant relationships)
Explanation:
Entity supertype
A entity supertype is a generic entity type which is related with one or more subtypes.
Use of entity supertype:
The reason for using entity supertype is to reduce redundant relationships and it is also used to minimize the number of nulls.

</em>
<em>Folders are locked that's why he couldn't open any folder or file. There must be a prompt telling him that he doesn't have an access or authority to open those files. This could be done via Folder sharing in the network. And a shared folder can be customized by assigning the proper and correct permission to each user.</em>
