I am taking a Beginners Java course and I am trying to complile a program I wrote but I keep getting errors that my
char code variable is not initiating. The problem is that I have to use input from a command line prompt to compare values in an if else statement. I have been looking at this thing for hours. Please keep in mind that I am extremely new at Java. It may be a simple fix but I am not sure what it is. Here is the source code for my java file:
//Discount.java
import java.io.*;
import java.text.DecimalFormat;
public class Discount {
public static void main(String args[]) {
// Introduction
System.out.println("\n Class: Java Beginning Programming"
+ "\n Lab/Assignments: A03 Discount"
+ "\n Student: Nakijma Nelson"
+ "\n Date: 03/01/2007");
//declare varibles
float price = 0,
discount = 0,
disAmount= 0,
disPrice = 0;
String value = "";
//declare buffered reader
BufferedReader reader;
reader = new BufferedReader(new InputStreamReader(System.in));
DecimalFormat twoDigits = new DecimalFormat("0.00");
//Get and covert user input from command line
try {
System.out.print("\n\tEnter Price ........... ");
value = reader.readLine();
// convert string to float
price = Float.parseFloat(value);
System.out.print("\n\tEnter Price Code...... ");
value = reader.readLine();
char code = value.charAt(0);
//convert string to char
} // end try block
catch (IOException ioe) {
System.out.println("\n I O Exception Occurered");
} // end catch
//define conditions
if(code == 'H'){
discount = .5F ;
}
else if(code == 'F'){
discount = .4F ;
}
else if(code == 'T'){
discount = .35F ;
}
else if(code == 'Q'){
discount = .25F ;
}
else if(code == 'Z'){
System.out.println("\n No Discount.");
System.exit(1) ;
}
else {
System.out.println("\n Incorrect Value Code.");
System.exit(2);
}
// evalute expressions
disAmount = price * discount;
disPrice = price - disAmount;
//display results
System.out.println("\n Price Code = > \t" + code);
System.out.println("\n Original Price = > \t $" + twoDigits.format(price));
System.out.println("\n Discount Amount = > \t $" + twoDigits.format(disAmount));
System.out.println("\n Disconnted Price = > \t $" + twoDigits.format(disPrice));
} //end main
} //end Class
These are the area a few of the error messages I get when I try to compile the file.
Discount.java :50: can not find symbol
symbol: variable code
location: class Discount
if(code=="H") {
/\ -------> (arrow is under the code variable)
......etc. for the rest of the conditions in the if..else statement.
Any help would be greatly appreciated. Thanks
