我需要使用合理的单位将文件大小显示为String.

例如

1L ==> "1 B";
1024L ==> "1 KB";
2537253L ==> "2.3 MB"

等等

我找到了之前的答案,我觉得这并不令人满意

我提出了自己的解决方案,它有类似的缺点:

private static final long K = 1024;
private static final long M = K * K;
private static final long G = M * K;
private static final long T = G * K;

public static String convertToStringRepresentation(final long value){
    final long[] dividers = new long[] { T, G, M, K, 1 };
    final String[] units = new String[] …
