Format numbers in java

How do I get these formats in java?

Input:

1223893
180703
80967
1461
开发者_开发技巧700

Output :

1,223,893
180,703
80,967
1,461
700

I will be always converting one by one number, this was just to get more examples.

you can read up on java number formatting here

so you would do something like this:

DecimalFormat myFormatter = new DecimalFormat('###,###,###');
String output = myFormatter.format('1223893');

if you output the output var it should have 1,223,893

Look for "grouping" and "thousands separator" here. DecimalFormatSymbols provides setGroupingSeparator(',') and you can set it on a DecimalFormat, together with setGroupingSize(3). To illustrate:

DecimalFormat df = new DecimalFormat();
df.getDecimalFormatSymbols().setGroupingSeparator(',');
df.setGroupingSize(3);
System.out.println(df.format(1223893)); // prints 1,223,893

You could use DecimalFormat.

Take a look at the DecimalFormat class.
