Passing boolean parameter to method

When I try passing a boolean parameter which is declared locally in another method the compiler delivers the the error:

Error:(40, 71) java: cannot find symbol symbol: variable frei
location: class flugVerein

the method that gets the boolean variable passed: 

public static void verfügbar(int[] flugAnzahl, String[] vorname, String[] bezeichnung, int[] zeit, boolean frei)

where the variable is declared: 

public static void ganzeTag(int[] zeit, String[] vorname, String[] nachname, String[] bezeichnung) {
    Scanner sc = new Scanner(System.in);
    System.out.println("Geben Sie die Bezeichnung des Fluges ein: ");
    String eingabe = sc.nextLine();
    boolean frei = false;

the method call in the main method: 

verfügbar(flugAnzahl, vorname, bezeichnung, zeit, frei);

You can't access the frei variable since you are in a different method. It was declared in the ganzeTag method, but you are trying to access it in the main method. There are a few things you can do. The easiest way in my opinion is to make it a field.

private static boolean frei;

Then in the ganzeTag method:

public static void ganzeTag(int[] zeit, String[] vorname, String[] nachname, String[] bezeichnung) {
    Scanner sc = new Scanner(System.in);
    System.out.println("Geben Sie die Bezeichnung des Fluges ein: ");
    String eingabe = sc.nextLine();
    frei = false; // don't put the boolean.

Actually, you don't even need that line, because the default value for the boolean field is false.

public static void ganzeTag(int[] zeit, String[] vorname, String[] nachname, String[] bezeichnung) {
    Scanner sc = new Scanner(System.in);
    System.out.println("Geben Sie die Bezeichnung des Fluges ein: ");
    String eingabe = sc.nextLine();

@Jwan I think you're referring to a local variable.
