Write code to get human Readable Byte Count
//package com.book2s; public class Main { public static void main(String[] argv) { long bytes = 42; System.out.println(humanReadableByteCount(bytes)); }/* ww w . jav a 2 s .c o m*/ public static final String humanReadableByteCount(long bytes) { if (bytes < 1024) return bytes + " B"; int exp = (int) (Math.log(bytes) / Math.log(1024)); String pre = "KMGTPE".charAt(exp - 1) + "iB"; return String.format("%.1f %s", bytes / Math.pow(1024, exp), pre); } }
