Hi,

I've ran this and it does say Enter gender but it won't work beyond that. I'm guessing you want to enter m and it prints MALE and f to print FFEMALE. If you do then you've got gender==f and gender==m
your problem is here.
You've also got int m=0, f=0, not sure why these are here.

why should i do to run this program?
when i input F the output is Female and when i input M the output is Male? Please help me

Your problem is your if statements. At the moment you've got gender==f
And from this statement

int m=0, f=0;

f and m are integers.

f is an int so when you type 'f' it won't match. You need to change it so it will match to the character you type.

gender=='f' //This is now matching it to the character 'f' not the variable.

and the same for the other if statement.
It should work then.

Enter gender: f
FEMALE

Press any key to continue...

why should i do to remover the Exception?

Mine isn't doing that, this is what I've got and its working as you say it should. Can you see what's different from yours`

import java.io.*;
public class gender{
public static void main(String [] args) throws Exception{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
 
char gender;
System.out.print("Enter gender: ");
gender=(char)br.read();	
 
if(gender=='f'){
System.out.println("FEMALE");
}
if(gender=='m'){
System.out.println("MALE");
 
}
 
}
}

ok i done Thanks
