}

public static double find_distance(int x, int y){

}

public static void print(int[] pos){

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

System.out.print(pos[i]+" , ");

System.out.println();

}

public static void print(double[] distance){

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

System.out.println();

}

hi can some one help me in fixing this erros in codes as i coundt understand the errors in it.
