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!
Answer:
There are no statements in the question, so I explained the whole code.
Explanation:
A map consists of key - value pairs. The put method allows you to insert values in the map. The first parameter in the put method is the key, and the second one is the value. Also, the keys must be unique.
For example, map.put("123", "John Smith"); -> key = 123, value = John Smith
Even though the key 123 is set to John Smith at the beginning, it will have the updated value Steve Yao at the end. That is because the keys are unique.
Note that the key 222 also has Steve Yao for the value, that is totally acceptable.
The kind of website which would best suit Hayne's needs is a: C) Dynamic website.
A website is the collective name that is used to describe series of interconnected webpages having a unique domain name.
Basically, a website is an HTML document which comprises codes, tags, images, audios, and videos that are integrated to make them responsive and interactive with clients (end users).
