    Default NEED HELP ASAP PLEASE!!!

    am from the u.k and a newbie to java and i need to create a Body Mass Index Calculator....ive been trying for awhile going through java books but can't seem to get it right....can any one please create a BMI calculator which is really simple and shows weight status table. i have to create this table using Jpad pro....only the javascript code is required so it works without errors when compiled on Jpad pro.

    i managed to create this as simple as i can i have ONE ERROR...
    public class BMI
    {
     
    public static void main(String[] args) {
    int weight; //weight
    int height; //height
    int BMI; //BMI
    char Overweight=0; //Overweight
    char Normal_Weight=0; //Normal Weight
    char Underweight=0; //Underweight
    Scanner input = new Scanner(System.in);
     
    System.out.print("Enter the weight: ");
    weight = input.nextInt();
    System.out.print("Enter the height: ");
    height = input.nextInt();
    input.close();
     
    BMI = weight / height;
    System.out.println("BMI (Body Mass Index): " + BMI);
    if (BMI >= 25 ) {
    BMI = Overweight;
    System.out.print("BMI = ");
    }
    }
    if anyone can make it any more simple then please do....and also add the the weight status table if its possible

    thhanx in advance!

    where is the error?

    For starters, I think you are missing a bracket at the end, but I'm not sure.

    Compiling H:\New Folder (3)\dhondhuuuuuuuuuuuuuuuuuu\BMI.java
    The current directory is: H:\New Folder (3)\dhondhuuuuuuuuuuuuuuuuuu
    Command line: "C:\Java\jdk1.6.0_14\bin\javac.exe" -deprecation -g -classpath H:\NEWFOL~3\DHONDH~1 "H:\New Folder (3)\dhondhuuuuuuuuuuuuuuuuuu\BMI.java"
    H:\New Folder (3)\dhondhuuuuuuuuuuuuuuuuuu\BMI.java:32: reached end of file while parsing
    }

    You need to put that bracket at the end. Always make sure every parenthesis/bracket/square bracket has a matching mate (the exception being inside of comments or strings).

    Less errors is not always an indication that you're making progress in making your program work as intended. post the details on these other errors you are getting.

    Also, make sure to surround your code with [highlight=Java]// code goes here[/highlight].

    You were missing a bracket and I'm assuming that your forgot to import Java.util.Scanner;
    Once I added both of those the code worked for me.
    import java.util.Scanner;
     
    public class BMI {
       public static void main(String[] args) {
          int weight; //weight
          int height; //height
          int BMI; //BMI
          char Overweight=0; //Overweight
          char Normal_Weight=0; //Normal Weight
          char Underweight=0; //Underweight
          Scanner input = new Scanner(System.in);
     
          System.out.print("Enter the weight: ");
          weight = input.nextInt();
          System.out.print("Enter the height: ");
          height = input.nextInt();
          input.close();
     
          BMI = weight / height;
          System.out.println("BMI (Body Mass Index): " + BMI);
     
          if (BMI >= 25 ) {
             BMI = Overweight;
             System.out.print("BMI = ");
          }
       }
    }

    Cross posting lets people waste time answering questions that have been answered already on another forum.

    Cross posting is posting your question on multiple forums. This can lead to the same question being answered independently on both forums, wasting people's time. Different forums have different rules regarding cross posting.

    Here at JavaProgrammingForums.com, we're not against cross-posting, however we do ask that you do post links to these other sites so the discussion can be coherent and connected between the two different forums.
