Write a java program to print the division of certificate.

Question

1.00/5 (1 vote)

See more:

The division is determined as follows: Rate from 0 to less than 2:"Fail" Rate from 2 to less than 3:"Third" Rate from 3 to less than 4:"Second" Rate from 4 to 5:"First"

What I have tried:

Java

package test3;
import java.util.*;

public class Test3 {

   
    public static void main(String[] args) {
      Scanner input = new Scanner(System.in);
           System.out.print("Enter the grade : ");

             double n = input.nextDouble();
      
      if(n>=0&&n<2)System.out.println("Fail");
      else if(n>=2&&n<3)System.out.println("Third");
       else if(n>=3&&n<4)System.out.println("Second");
       else if(n>=4&&n<5)System.out.println("First");
    }
    
}

And you have a question or a problem ?

Member 15766438 24-Sep-22 17:55pm

Yes, is the attempt correct for what is stated in the question?

That' not even a correct question. It doesn't specify what the expected input is, so how are you going to write code to process the unknown?

Oh my God I don't know. What is the appropriate solution to the question?
Concept The question for me asks for the certificate to be divided so that the average(GPA) ranges from 0 to 5 (University GPA)

Like I said, this isn't even a good assignment. What is a "certificate"? How does that relate to an average GPA? Where is the average coming from or do you have to calculate it? From what data? You're only getting a single value, so ...

The person to be asking question about this assignment is your teacher.

ok,I will ask the teacher..., thank you

I don't know if my answer is correct
I have tried many times but no result

You know if code is correct if your tests give expected result.

The best way to find out if your program does what it's supposed to do is to run it and see what it does. Does it yield the correct results in all cases?

Run it with 0,1,2,3,4 and 5.
Try some intermediate values - 1.9, 3.4, etc.
Make sure you try the edge cases - the one you test for in your if statements.
You have the user input the grade. What happens if they enter -3.7 or 7.5?

When any of these tests fail use the debugger to determine where your logic went wrong. When you change code to fix an error you'll need to rerun all your tests again to make sure you didn't break something somewhere else.

Good luck!
