Question

how to call maze1 and maze2 object to be use in print method

maze2.maze[i][j]

maze2 is object

maze[i][j] is variable from different class

i just need help in calling object to be used in the print method and main will call print method to display.

import java.io.*;

public class MazeSolver {

      

//===========================================
// object reader
//==========================================
   public static void read()throws FileNotFoundException,IOException{      
       reader maze1 = new reader(new FileReader("maze1.txt"));
       reader maze2 = new reader(new FileReader("maze2.txt"));
   }

//===================================
// Print
//===================================

//maze1
   public static void print(){  

       System.out.println("Maze 1: \n");      
       for (int i=0; i<7; i++) {
           for (int j=0; j<7; j++) {
       System.out.print(maze1.maze[i][j]);
       System.out.print(' ');
          }
           System.out.println();
       }

       System.out.println("\nMaze 2: \n");
       //maze2   
       for (int i=0; i<7; i++) {
           for (int j=0; j<7; j++) {
       System.out.print(maze2.maze[i][j]);
       System.out.print(' ');
          }
           System.out.println();
       }
   }

//===========================================
// Main
//==========================================

   public static void main(String[] args){

       print();

   }//end main

}//endclass

You can declare maze1 and maze2 as class level static variable. and add throws in main method like below:

import java.io.*;

public class MazeSolver {

private static reader maze1, maze2;

//===========================================
// object reader
//==========================================
public static void read()throws FileNotFoundException,IOException{
maze1 = new reader(new FileReader("maze1.txt"));
maze2 = new reader(new FileReader("maze2.txt"));
}

//===================================
// Print
//===================================

//maze1
public static void print(){

System.out.println("Maze 1: \n");
for (int i=0; i<7; i++) {
for (int j=0; j<7; j++) {
System.out.print(maze1.maze[i][j]);
System.out.print(' ');
}
System.out.println();
}

System.out.println("\nMaze 2: \n");
//maze2   
for (int i=0; i<7; i++) {
for (int j=0; j<7; j++) {
System.out.print(maze2.maze[i][j]);
System.out.print(' ');
}
System.out.println();
}
}

//===========================================
// Main
//==========================================

public static void main(String[] args)throws FileNotFoundException,IOException{
   read();
print();

}//end main

}//endclass
