I believe the correct answer from the choices listed above is the first option. The word chronograph means <span>a timepiece fitted with a recording device that marks down exact intervals of time. Hope this answers the question. Have a nice day.</span>
Answer:
// here is code in java.
import java.util.*;
// class definition
class BookstoreCredit
{
/* method that display descriptive message with name and grade point */
public static void fun(String name,double grade)
{
// multiply grade with 10
grade=grade*10;
// print the message
System.out.println(name+"\'s average grade is $"+grade);
}
// main method of the class
public static void main (String[] args) throws java.lang.Exception
{
try{
// scanner object to read innput
Scanner s=new Scanner(System.in);
// variables
String s_name;
double grade;
System.out.print("Please enter the name:");
s_name=s.nextLine();
System.out.print("Please enter the grade point:");
grade=s.nextDouble();
}catch(Exception ex){
return;}
}
}
Explanation:
Create variable s_name of string type and grade of double type.Read the student name and grade from user.call the fun() with these two parameter, where grade is multiplied by 10 and print the descriptive message which has student name and echoes the grade point average.
Output:
Please enter the name:john
Please enter the grade point:3.2
john's average grade is $32.0
Answer:
Reference type,generic type
Explanation:
Reference types are used by a reference that maintains a reference (address) to the object but not the object itself. Because reference kinds reflect the variable's address rather than the data itself, assigning a reference object to another does not copy the information. Instead, it produces a second duplicate of the reference, which relates to the same heap place as the initial value.
Examples of reference types are Classes, Arrays,, Interfaces etc.
A generic type is a generic class or interface that is parameterized over kinds. Essentially, generic types enable you to write a particular, generic class (or method) that operates with distinct kinds, enabling code to be reused.
The class Object describes the conduct of all Java objects. However, it does not describe the conduct of all Java data structures. That's because not all Java data structures are objects. Some of them are primitive values that can be stored in object variables, but they are not objects themselves.
Unlike object types, primitive types are not sub types or super types.
