Help with my Java project; cannot find symbol error

Help with my Java project; cannot find symbol error

#1

I’m wondering why my main method doesn’t recognize my other methods? Im using Geany, (we’re supposed to for school) and it will autofill the method I am trying to call, but I get a “cannot find symbol java52” error when I try to compile. Why is this? Everything else has been working fine.

I have three classes thus far.

Here is my driver class. This is the one thats having issues. I included the other classes so that you guys can have all the information.

import java.util.Scanner;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
public class LibraryCollectionManager
{

public static void main (String[] args)
{
int quitVal = 0; //variable used to pass to end program
int patronCount = 0; //used to keep track of patrons so that arrays can be managed correctly
String choice = “blank”; //varaible to represent menu choices
Scanner input = new Scanner(System.in);
while (quitVal == 0)
{

  	launchMenu();
  	
  	System.out.print("Make a choice by typing the value in parenthesis.  \n Ex : Choice (val), type >val. : ");
  	choice = input.nextLine();

  	switch (choice.toLowerCase()){
  		case "a1" : System.out.println("DEBUG: You chose to display all materials");
  			break;
  		case "a2" : System.out.println("DEBUG: You chose to search by author");
  			break;
  		case "a3" : System.out.println("DEBUG: You chose to search by title");
  			break;
  		case "a4" : System.out.println("DEBUG: You chose to search by type");
  			break;
  			case "a5" : System.out.println("DEBUG: You chose to Checkout a material");
  			break;
  		case "a6" : System.out.println("DEBUG: You chose to Return a checked out material");
  			break;
  			case "a7" : System.out.println("DEBUG: You chose to Display all overdue materials");
  			break;
  		case "a8" : System.out.println("DEBUG: You chose to Add a material");
  			break;
  		case "a9" : System.out.println("DEBUG: You chose to Remove a material");
  			break;
  		case "b1" : System.out.println("DEBUG: You chose to Display all patrons");
  		displayPatrons(); //this is where I am having issues or at least what java is complaining about
  			break;
  		case "b2" : System.out.println("DEBUG: You chose to Display all patrons with overdue >materials ");
  			break;
  		case "b3" : System.out.println("DEBUG: You chose to Add a new patron");
  			break;
  		case "b4" : System.out.println("DEBUG: You chose to Remove a patron ");
  			break;
  		case "c1" : System.out.println("DEBUG: You chose to Load Data from File ");
  			break;
  		case "c2" : System.out.println("DEBUG: You chose to Save Data to File");
  			break;
  		case "d4" : System.out.println("DEBUG: You chose to quit");
  			quitVal++;
  			break;
  		}
  	
  
  }

}//end of main

public static void launchMenu()
{
Scanner inputFile = null;
//Try to open the file
try
{
inputFile = new Scanner(new FileInputStream(“menu.txt”));
}
catch(FileNotFoundException e)
{
System.out.println(“Could not find or open file”);
}

  	do
  	{
  		System.out.println(inputFile.nextLine());
  	}while (inputFile.hasNextLine());

}
}//end of FinalProject class

Here is my patron method class, it contains the methods I am trying to call

import java.util.Scanner;
public class PatronCollection
{
//instance variables
int collectionMaxSize;
Patron[]patronCollection;

public void displayPatrons()
{
for (int i = 0; i < patronCollection.length; i++)
{
System.out.println(patronCollection[i].toString() );
}
}

public Patron[] addPatron(Patron[] patronCollection, int patronCount)
{
Scanner input = new Scanner(System.in);
System.out.print(" \n Enter name of new patron : “);
String name = input.nextLine();
System.out.print(” \n Enter ID of new patron : ");
String id = input.nextLine();

  Patron patron = new Patron(id, name);
  patronCollection[patronCount] = patron;
  patronCount++;
  
  return patronCollection;

}

} // end of PatronCollection class

Then here is my patron class, it contains the information on patrons as an object

public class Patron
{
//instance variable
String id;
String name;
//constructor methods
public Patron()
{
System.out.println(“There is no information given on this patron…”);
}
public Patron(String id)
{
this.id = id;
}
public Patron(String id, String name)
{
this(id);
this.name = name;
}
//getter and setter methods
public String getID()
{
return id;
}
public void setPatronID(String inputID)
{
this.id = inputID;
}
public String getName()
{
return name;
}
public void setName(String inputName)
{
this.name = inputName;
}
//copy constructor
public Patron (Patron inputPatron )
{
//copies instance variables
name = inputPatron.getName(); //copies product name
id = inputPatron.getID(); // copies product price
}
public String toString()
{

  return " PATRON , " + id + " , " + name ; 

}
//equals method
public boolean equals (Patron inputPatron)
{
if ((id.equals(inputPatron.getID())) && (name.equals(inputPatron.getName())) ) //compares all instance variables
{
return true;
}
else
{
return false;
}
}
}//end of patron class

Thank you!
