Answer 1

Adapting the answer from over here it should look something like

public static String withSuffix(long count) {     if (count < 1000) return "" + count;     int exp = (int) (Math.log(count) / Math.log(1000));     return String.format("%.1f %c",                          count / Math.pow(1000, exp),                          "kMGTPE".charAt(exp-1)); } 

---

Test code:

for (long num : new long[] { 0, 27, 999, 1000, 110592,                              28991029248L, 9223372036854775807L })    System.out.printf("%20d: %8s%n", num, withSuffix(num)); 

Output:

                   0:        0                   27:       27                  999:      999                 1000:    1.0 k               110592:  110.6 k          28991029248:   29.0 G  9223372036854775807:    9.2 E

//To remove zero from 1.0k

public static String coolNumberFormat(long count) {         if (count < 1000) return "" + count;         int exp = (int) (Math.log(count) / Math.log(1000));         DecimalFormat format = new DecimalFormat("0.#");         String value = format.format(count / Math.pow(1000, exp));         return String.format("%s%c", value, "kMBTPE".charAt(exp - 1));     }
