i trying setup minesweeper game having problems carrying on new 'v' int board file. below list of things have done.i hope have said below makes sense, original minesweeeper base game code can found @ bottom of this.
- made easy.java file contains:
import java.util.scanner;
public class easy{ public static int b; public static void setvariable(int s) { b = s; } public static int getvariable() { return b; } } added public static int top of mines.java (under
private final int frame_height = 290;
)
added main method withing public void run of mines.java file:
system.out.println("please enter number difficulty"); system.out.println("1: easy 2: medium 3: hard"); scanner kb = new scanner(system.in); int difficulty = kb.nextint(); system.out.println("difficulty set to: " + difficulty); if(difficulty==1){ easy.setvariable(40); v = easy.getvariable(); system.out.println(v); system.out.println("easy mode chosen"); }i unsure on how link board.java file take value of 'v' have tried
int n_mines = mines.v;
however doesn't see value set in above piece of code if set v equal number see's this. in previous code "system.out.println(v);" prints out correct variable board.java not see number. how supposed go this?

edit constructor of board class accept number of mines.
private int n_mines = 40; // default public board(int mines, jlabel statusbar) { this.n_mines = mines; this.statusbar = statusbar; make new board(20, new jlabel()); easier game
