使用java重新解决八数码问题

import java.io.*;
//文件读取
public class EightFileRead {
	FileInputStream fis = null;
	public EightFileRead(String filename) {
		try {
			fis = new FileInputStream(filename);
		} catch (FileNotFoundException e) {
			System.out.println("File read error!");
			System.exit(0);
		}
	}
	public int readFileNum() {
		int b = 0;
		try {
			while (b > 58 || b < 48) {
				b = fis.read();
			}
		} catch (IOException e) {
			System.out.println("Data input error!");
			System.exit(0);
		}
		b = b - 48;
		return b;
	}

	public void close() {
		try {
			fis.close();
		} catch (IOException e) {
			System.out.println("File close error!");
			System.exit(0);
		}
	}
}
