读取文件资源

读取文件资源的两个方法

public static byte[] readRes(String s1, int i1)          //读取文件资源
    {
        byte abyte0[];
        try
        {
            InputStream inputstream = C.getClass().getResourceAsStream(s1);
            abyte0 = new byte[i1];
            int k1 = 0;
            int j1;
            for(int l1 = i1; l1 > 0 && (j1 = inputstream.read(abyte0, k1, l1)) >= 0; l1 -= j1)
            {
                k1 += j1;
            }

            inputstream.close();
        }
        catch(Exception exception)
        {
            abyte0 = null;
        }
        return abyte0;
    }

byte playerbyte1[] = readRes("/players_new.png", 11785);                                                                                             

aA = readRes("/players_new.bin", 648)

///////////////读取文件资源

private String readHelpText()

return sb.toString();
}
catch (Exception e){System.out.println("Unable to create stream");}
return null;

}
