By default, if you do not implement a constructor, the compiler will use an empty constructor (no parameters and no code). The following code will create an instance of the MyObject class using the default constructor. The object will have the default vauesfor all the attributes since no parameters were given.
MyObject obj = new MyObject();
Another type of constructor is one with no parameters (no-arg constructor). It is similar to the default, except you actually create this constructor. The contents of the the constructor may include anything. To call a no-arg constructor, use the same line of code as above. The constructor can look like the one below:
public MyObject() {
System.out.println("This is a no-arg constructor");
}
Lastly there is the parameterized constructor. This type of constructor takes in parameters as inputs to assign to values in the newly created object. You call a parameterized constructor as follows:
MyObject obj = new MyObject("Bob", 20);
The constructor will look like this:
public MyObject(String name, int age) {
this.name = name;
this.age = age;
}
In the constructor, the keyword "this" refers to the object, so this.name is a private global variable that is being set equal to the inputted value for name, in this case "Bob".
Hope this helps!

Audience - School Board
Answer:
Option A is the correct choice answer for the above question.
Explanation:
In an MS-Powerpoint document, when a user wants to copy the selected shape and drag that shape for use in slides then he needs to--
- Select the shape
- Press the Ctrl key and
- drag that shape on the slide of the powerpoint.
Then the user gets the shape on the slide for their personal use.
The question scenario also suggests the same which is described above. hence Option A is the correct answer while the other is not because--
- Option B suggests 'ESC' which is used to escape any running program.
- Option C suggests about ALT key which is of no use for the MS-Powerpoint document.
- Option D suggests about TAB key which is used to make the space between two texts or diagram.
