writing a java program

[arishma]

a program that expects a numeric grade as input and outputs the corresponding letter grade. the program uses the following grading scale:
numeric range letter grade
0 39 E
40 49 D
50 56 C
57 63 C+
64 70 B
71 77 B+
78 84 A
85 100 A+

required to use compound boolean operators

Hi Arishma! Welcome to TSDN!
Check out the java.util.Scanner class for reading in your numeric value and then find the correct Letter for it. If you're new to Java, check out this article - it will teach you, what you have to know to solve this problem.

import java.io.*;
class testscore {
    public static void main(String[] args) {
 
        int testscore;
        char Grade;
             char Grade;//To print the student grade on the screen
 
       if (testscore >=0 && testscore <= 39) 
            System.out.println( "E" ) ; 
         if (testscore >= 40 && testscore <= 49)
            System.out.println( "D" ) ;
        if (testscore >= 50 && testscore <=56) 
            System.out.println( "C" ) ;
         if (testscore >= 57 && testscore <=63)
            System.out.println( "C+" ) ;
        if (testscore >=64 && testscore <= 70)
            System.out.println( "B" ) ;
      if (testscore >=71 && testscore <= 77)
        System.out.println( "B+" ) ;
      if (testscore >=78 && testscore <= 84)
           System.out.println( "A" ) ;
     if (testscore >= 85 && testscore <= 100)  
        System.out.println( "A+" ) ;
 
 
        return Grade;//method to return student grade                    
                       }
 
}
 

this is what i have got but 1 error where help pliz

[arishma]

thanx a ton i think i have got it now

thanx a ton i think i have got it now

Well done for finding it!

One little tip:
When you ask for help next time, don't just state, that there is an error, but also tell us, what error it is (what it is called, e.g. NullPointerException, IOException, ...) and in what line it occurs (the compiler will write something like

Exception in thread "main" java.lang.NullPointerException
    at java.io.FileInputStream.<init>(Unknown Source)
    at yourProject.yourClass.main(Exceptions.java:12)
 

and then 12 would be the line you're looking at).
