Answer:
public class Invitation
{
private String hostname;
private String address;
public Invitation(String n, String a)
{ // constructor that accepts two strings.
hostname = n;
address = a;
}
public String getHostname()
{
return hostname;
}
public void setAddress(String a)
{
address = a;
}
public String invite(String guest)
{
return "Hello" +guest+ ", you are invited to my party at " +address+". "+hostname+".";
}
public Invitation(String host, String address)
{
this.address = address;
this.hostname = host;
}
}
Explanation:
The Java program defines a class called "Invitation". The class constructor has two string arguments or parameters for the host of the event and the address. The invite method is used to generate the string invite message with the name of the guest as the argument. Use the "setAddress" method to set a new location of the event and the "getHostname" to get the name of the event host.
Answer:
The solution code is written in R script.
- #string variable
- character_str<- "Hello World"
- #logical variable
- logic <- a > b
- #Missing value
- myVec <-c(1, 2, 3, NA)
- #Use class to check data type
- class(character_str)
- class(logic)
- class(myVec)
Explanation:
A string variable is a variable that hold a string (the letters enclosed within quotation marks) (Line 2)
A logical variable is a variable that hold a logical value (either True or False). The logical value is created by comparing two variables (Line 5).
In R, missing value is an unknown value which is represented by NA symbol (Line 8).
We can use in-built method <em>class </em> to check for the variable type in R (Line 11-13). For example, the output of <em>class(character_str)</em> is "<em>character</em>"

Answer:
The correct answer to the following question will be 2. the operator new.
Explanation:
New operator is used to allocating the memory to the instance object.The new object can be created by using a "new" keyword in java .
Syntax of using 'new' operator is :
class_name object_name=new class_name() // it allocated the memory to the class
For Example :
ABC obj = new ABC;
Now, this time obj points to the object of the ABC class.
obj = new ABC ();
call the construction of ABC class
