I can't display the right output (else if statement)
 

Hi everyone, I hope you guys can help me.

Output

Enter your department number:
You belong to:

1-3 = Mr.X
4-7 = Mr.Y
8-9 = Mr.Z

------
Error:
When I input numbers from 1-9, the output that is displayed is always "You belong to: Mr. Z"

Here's my code:

import java.io.*;

public class Test5

{

        public static BufferedReader input=new BufferedReader (new InputStreamReader(System.in));

        public static void main(String args[])

        {

                String Department;

                int dept=0;

                try{

                System.out.println("Enter Department:");

                Department=input.readLine();

                }

                catch(IOException ioe) {}

                

                if (dept<=9){

                System.out.println("You belong to: Mr.Z");

                }else if (dept<=7){

                System.out.println("You belong to: Mr.Y");

                }else if (dept<=3){

                System.out.println("You belong to: Mr.X");

                }

        }

}

Re: I can't display the right output (else if statement)
 

numbers between 1-9 always are <=9. so you must specify an interval inside if-if else clause
like :
if(dept>7 && dept<=9)
System.out.println("You belong to: Mr.Z");
}else if (dept>3 && dept<=7){
System.out.println("You belong to: Mr.Y");
}else if (dept<=3){
System.out.println("You belong to: Mr.X");
}

@ede
I tried your suggestion, but the output always display "you belong to Mr.X" =(

import java.io.*;

public class Test5

{

        public static BufferedReader input=new BufferedReader (new InputStreamReader(System.in));

        public static void main(String args[])

        {

                String Department;

                int dept=0;

                try{

                System.out.println("Enter Department:");

                Department=input.readLine();

                }

                catch(IOException ioe) {}

                

                if (dept>7&&dept<=9){

                System.out.println("You belong to: Mr.Z");

                }else if (dept>3&&dept<=7){

                System.out.println("You belong to: Mr.Y");

                }else if (dept<=3){

                System.out.println("You belong to: Mr.X");

                }

        }

}

I also tried, but the error is still the same. >.<

if (dept<=3){

   System.out.println("You belong to: Mr.X");

   }else if (dept>=4&&dept<=7){

   System.out.println("You belong to: Mr.Y");

   }else if (dept>=8&&dept<=9){

   System.out.println("You belong to: Mr.Z");

   }

Re: I can't display the right output (else if statement)
 

Same mistake in both cases

• you store user input into Department but compared variable is dept, I think you forgot to parse String Department to integer dept so whole time you run check on null value of dept int dept=0;
• your last attempt iCez actually work once parse implemented

  if (dept<=3){
  
     System.out.println("You belong to: Mr.X");
  
     }else if (dept>=4&&dept<=7){
  
     System.out.println("You belong to: Mr.Y");
  
     }else if (dept>=8&&dept<=9){
  
     System.out.println("You belong to: Mr.Z");
  
     }

• Another option is code bellow which also deal with number out of boundaries 1 - 9

import java.io.*;

public class Test5

{

        public static BufferedReader input=new BufferedReader (new InputStreamReader(System.in));

        public static void main(String args[])

        {

                String Department;

                int dept=0;

                try{

                System.out.println("Enter Department:");

                Department=input.readLine();

                dept = (int) Integer.parseInt(Department);

                }

                catch(IOException ioe) {}

                

                if(dept>7 && dept<10){

                System.out.println("You belong to: Mr.Z");

                }else if (dept>3 && dept<8){

                System.out.println("You belong to: Mr.Y");

                }else if (dept>0 && dept<4){

                System.out.println("You belong to: Mr.X");

                }

                else{

                System.out.println("Department not recognice");

                }

        }

}

@peter_budo
thx for the help! Actually I didn't forgot the parse thing, I just don't know how it works. >.< We we're not yet taught about that. ~.~

Thx anyway, it was a big help. ^^
