Converting KB to MB, GB, TB dynamically

Question

public String size(int size){
    String hrSize = \"\";
    int k = size;
    double m = size/1024;
    double g = size/1048576;
    double t = size/1073741824;

            


        

Answer 1

public class FileSizeCalculator {

    String[] fileSizeUnits = {"bytes", "KB", "MB", "GB", "TB", "PB", "EB", "ZB", "YB"};

    public static void main(String[] args) {
        FileSizeCalculator fs = new FileSizeCalculator();
        String properFileSize = fs.calculateProperFileSize(2362232012l);
        System.out.println("Proper file size: " + properFileSize);
    }

    public String calculateProperFileSize(long noOfBytes){
        String sizeToReturn = "";// = FileUtils.byteCountToDisplaySize(bytes), unit = "";
        double bytes = noOfBytes;
        int index = 0;
        for(index = 0; index < fileSizeUnits.length; index++){
            if(bytes < 1024){
                break;
            }
            bytes = bytes / 1024;
        }
        sizeToReturn = String.valueOf(bytes) + " " + fileSizeUnits[index];
        return sizeToReturn;
    }
}

Just add more file unit (if any missing), and you will see unit size up to that unit (if your file has that much length)
