如何在Java中将字节大小转换成可读格式？

SI（1 k = 1,000）

public static String humanReadableByteCountSI(long bytes) {    String s = bytes < 0 ? "-" : "";    long b = bytes == Long.MIN_VALUE ? Long.MAX_VALUE : Math.abs(bytes);    return b < 1000L ? bytes + " B" : b < 999_950L ? String.format("%s%.1f kB", s, b / 1e3) : (b /= 1000) < 999_950L ? String.format("%s%.1f MB", s, b / 1e3) : (b /= 1000) < 999_950L ? String.format("%s%.1f GB", s, b / 1e3) : (b /= 1000) < 999_950L ? String.format("%s%.1f TB", s, b / 1e3) : (b /= 1000) < 999_950L ? String.format("%s%.1f PB", s, b / 1e3) : String.format("%s%.1f EB", s, b / 1e6);}

二进制（1 K = 1,024）

public static String humanReadableByteCountBin(long bytes) {    long b = bytes == Long.MIN_VALUE ? Long.MAX_VALUE : Math.abs(bytes);    return b < 1024L ? bytes + " B" : b <= 0xfffccccccccccccL >> 40 ? String.format("%.1f KiB", bytes / 0x1p10) : b <= 0xfffccccccccccccL >> 30 ? String.format("%.1f MiB", bytes / 0x1p20) : b <= 0xfffccccccccccccL >> 20 ? String.format("%.1f GiB", bytes / 0x1p30) : b <= 0xfffccccccccccccL >> 10 ? String.format("%.1f TiB", bytes / 0x1p40) : b <= 0xfffccccccccccccL ? String.format("%.1f PiB", (bytes >> 10) / 0x1p40) : String.format("%.1f EiB", (bytes >> 20) / 0x1p40);

}

输出示例：

        SI     BINARY        0:        0 B        0 B       27:       27 B       27 B      999:      999 B      999 B     1000:     1.0 kB     1000 B     1023:     1.0 kB     1023 B     1024:     1.0 kB    1.0 KiB     1728:     1.7 kB    1.7 KiB   110592:   110.6 kB  108.0 KiB  7077888:     7.1 MB    6.8 MiB452984832:   453.0 MB  432.0 MiB         28991029248:    29.0 GB   27.0 GiB       1855425871872:     1.9 TB    1.7 TiB 9223372036854775807:     9.2 EB    8.0 EiB   (Long.MAX_VALUE)
