How to apply a mask to a string value

Question

I want to apply a format mask like “# 0” to my number field, which is a string like “6000”, I tried various types of formatting, but it didn’t help, can someone tell me how to handle this in android, please

I am looking for something like when I do this formatString("6000", "#,##0.00") , it should give me formatted output of 6,000.00

Answer 1

This should help:

  String yourString = "6000"; double value = Double.valueOf(yourString); DecimalFormat df = new DecimalFormat("#,##0.00"); System.out.println(df.format(value)); 

Answer 2

Just convert the string "6000" to a number, for example.

 double d = Double.parseDouble("6000"); 

Then use DecimalFormat as described here: How do I format a number in Java?
