So I am trying to open/close/reopen/read and array into a 1 dimensional array and a 2 dimensional array.

public class Assigntment2Condensed

{

   public static void main (String args) throws IOException

   {



//Creating the menu options



      System.out.println("nnPlease choose an option belown"

                          + "tA. Read Datan"

                          + "tB. Modify Datan"

                          + "tC. Clear Datan"

                          + "tD. Display Datan"

                          + "tE. Save Data to a filen"

                          + "tF. Quit");

      System.out.print("n=> ");                   

      //WHAT I NEED: While loop and a nested If statement



      //getting user input:: can create a method

      String input = keyboard.nextLine();      

      input = input.toUpperCase();     //what the user inputs will be made to an upper case char

      char charInput = input.charAt(0);   //gets the character in the 0 position



       //main methods

      int originalMap = getMap(new Scanner(new File("map.dat")));  //reads data into the array :: Menu Option A

      getShowArray(originalMap); //passing contents of original map into the method :: Menu Option D

      getWriteArray(modifiedMap); //method created to write the contents of the modified map to a file. :: Menu Option B



// Method classes     

//Read in array from file to a two dimen. array. returns array Map. :: Menu Option A

   public static int getMap(Scanner file)

   {  

      int index = 0;

      String map;



      Scanner keyboard = new Scanner(System.in);



      System.out.println("nnOpening 'map.dat' file and adding elements to the array....n");



      //open the file

      File file = new File("map.dat");



      Scanner openFile = new Scanner(file);    //reads in the file into the openFile instance



      //read the file contents

      while(openFile.hasNext())

      { 

         map = openFile.nextLine();



         //System.out.println(map);

         index++;



      }

      openFile.close();



      //read contents into an array



      File map2 = new File("map.dat");

      Scanner openFile2 = new Scanner(map2);



      int numArray = new int[index]; //creates Array

      for(int i = 0; i < numArray.length; i++)

      {

         numArray[i] = openFile2.nextInt();

         //System.out.print(numArray[i] + " " );



      }          







   //-=-===-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-==-=

      int rows = file.nextInt();

      int columns = file.nextInt();



      int map = new int[rows][columns];



      for(int i = 0; i < rows; i++)

      {

         for(int j = 0; j < columns; j++)

         {

            map[i][j] = file.nextInt();

            System.out.print(map[i][j] + "  ");

         }

         System.out.println("");

      }



      file.close();



      return map;

   }



//displaying the array when called :: Menu Option D

   private static void getShowArray(int originalMap)

   {

      for (int row = 0; row < originalMap.length; row++)

      {

         for(int col = 0; col < originalMap.length; col++)

            System.out.print(originalMap[row][col] + " | ");

         System.out.println();

      }

   }



//writing modifiedMap array to a txt file :: Menu Option B

   public static void getWriteArray(int modifiedMap)

   {

      dataInputStream inputFile = new DataInputStream(new fileInputStream("map.dat"));

      System.out.println("nWriting to the 'map.dat' file...");



      //write to binary file

      for (int i = 0; i < modifiedMap.length; i++)

         outputFile.writeInt(modifiedMap[i]);



      //close file

      outputFile.close();

      System.out.println("Done.");

   }





}

I am getting the error:

The "=-=-=-=-=-=-=-=-=-=-=-=-" is an indication of that the code prior to that line was previously outside of that method and anything below that was already working in that method. I need to create a menu option so when they click A the file is read into the program.

You can't have a method inside a method. The compiler thinks that public static int getMap(Scanner file) is inside your main method, and it's probably not what you're after.
