Compiler error cannot find symbol

[Janice Twomey]

Im not sure where the problem is help would be greatly appreciated

import java.*;
  
  
 public class PrintQuota {
  
 
   String[] a = null;
   private int studentID = 0;
   private int Balance = 200;
   private static int UnitCost = 2;
   private int pagesToPrint = 0;
   private static int setcurrentUnitCost = 2;
   private static int getcurrentUnitCost = 2;
   public int Print = 0;
   private int increaseBalance = 0;
   public static string studentName;
  
    
   public PrintQuota( int newStudentID ) {
     this.studentID = newStudentID;
     this.currentBalance = initialAllocation;
   }
   
       
   public int getID() {
     return studentID;
   }
  
   public int getName() {
     return studentName;
   }
  

    public int getBalance() {
   return currentBalance;
  }

    
   public void printPages(int numPages) {
     if ( (numPages * costPerPage) <= currentBalance ) {
       Balance = Balance - (numPages * costPerPage);
       System.out.println("Department of Computer Science, University National University of Elbonia");
       System.out.println("Student Name" + studentName);
       System.out.println("StudentID: " + studentID  + "\nPrinting number of pages... " + numPages +  "\nBalance Remaining: " + Balance+"c\n");
       System.out.println( "You are able to print %d pages\n\n", (Balance/costPerPage));

     }
     else
       System.out.printf("You do not have enough roubles in your account to print %d pages\n", numPages);
  }
    
  
   public int checkPages()
   {
     pagesToPrint = currentBalance/costPerPage;
    return pagesToPrint;
   }
    
 }

error is refering to the line public static string studentName

Hi and welcome to the Javaranch.

There is no such thing as string class there is however a String class. Classnames start with an uppercase character.

Thanks a lack of sleep is catchin up with me

Hi Janice,

Welcome to CodeRanch!

Java is case-sensitive, and string != String.

By the way, it's this case sensitivity which makes it important to be consistent with your variable naming. The Java convention is that classes start with a capital, and methods and variables start lower case. But your Balance and Print variables start with capitals - you'd be better off fixing that while you're at it.

Edit: ah, too slow!

Hi friend,
You use a IDE like Eclipse(http://www.eclipse.org/) to test your java programs instead of typing on notepad. Then you can easily detect these type of syntax errors.

I've fix a good bit but I'm still getting symbol errors

import java.*;
  
  
 public class PrintQuota {
  
 
   String[] a = null;
   private int studentID = 0;
   private int Balance = 200;
   private static int UnitCost = 2;
   private int pagesToPrint = 0;
   private static int setcurrentUnitCost = 2;
   private static int getcurrentUnitCost = 2;
   public int Print = 0;
   private int increaseBalance = 0;
   public static String studentName;
  
    
   public PrintQuota( int newStudentID ) {
     this.studentID = newStudentID;
     
   }
   
       
   public int getID() {
     return studentID;
   }
  
   public String getName() {
     return studentName;
   }
  

    public int getBalance() {
    return Balance;
  }

    
   public void printPages(int numPages) {
     if ( (numPages * UnitCost) <= Balance ) {
       Balance = Balance - (numPages * UnitCost);
       System.out.println("Department of Computer Science, University National University of Elbonia");
       System.out.println("Student Name" + studentName);
       System.out.println("StudentID: " + studentID  + "\nPrinting number of pages... " + numPages +  "\nBalance Remaining: " + Balance+"c\n");
       System.out.println( "You are able to print %d pages\n\n", (Balance/costPerPage));

     }
     else
       System.out.printf("You do not have enough roubles in your account to print %d pages\n", numPages);
  }
    
  
   public int checkPages()
   {
     pagesToPrint = currentBalance/costPerPage;
    return pagesToPrint;
   }
    
 }

[Buddhika Mawella]

In your program variable 'costPerPage' and 'currentBalance' are undefined. that's why you are getting symbol errors.

[Campbell Ritchie]

Disagree. You are better off not using IDEs at this stage.

[Wouter Oet]

I also disagree. This is a very simple error and the compiler will tell you exactly where it is. It's a very basic mistake and for me that is an indication that the topic starter is a beginner (nothing special here in the "Beginnning Java" forum). He should get to a level where he is able to spot such mistakes and familiarize himself with Java and its classes / api's and then consider using an IDE.

[Matthew Brown]

But what you do need to do is tell us the lines that you're getting errors .

Yes. Agree with you. that is the better way for a beginner.
