but which john
Explanation:
man people don't make sense you more man
Answer:
I don't think so. In today's computer era, many different solution directions exist for any given problem. Where OOP used to be the doctrine of choice, now you would consider it only when the problem at hand fits an object-oriented solution.
Reason 1: When your problem can be decomposed in many different classes with each many instances, that expose complex interactions, then an OO modeling is justified. These problems typically produce messy results in other paradigms.
Reason 2: The use of OO design patterns provides a standardized approach to problems, making a solution understandable not only for the creator, but also for the maintainer of code. There are many OO design patterns.
Answer:
Following are the program in java is given below
import java.util.*; // import package
public class Main // main class
{
public static void main(String[] args) // MAIN FUNCTION
{
Scanner scan2 = new Scanner(System.in);// scanner CLASS
System.out.println("Enter the Grade ");
char GRADE = scan2.next().charAt(0);//Read input by user
if(GRADE=='A' || GRADE=='B' || GRADE=='C' || GRADE=='D' || GRADE=='F' ) // //CHECK CONDITION
{
System.out.println("The GRADE is :" +GRADE); // display grade
}
else // Else block
{
System.out.println(" Input Error"); // display message
}
}
}
Output:
Enter the Grade
D
The GRADE is :D
Explanation:
Following are the description of program
- Create the object of scanner class for read the value of grade by the user .
- Read the value of "GRADE" variable by using the scanner class object scan 2
- Now check the condition in if block if the "GRADE" is 'A' or 'B' or 'C' or 'D' or 'F' then display the value of the GRADE variable otherwise else block is executed and input error message is displayed .
