Apply formatting to variables in Java

Question

Is there a simple way to format variables on a GUI with spaces (or commas) between so its easier to read.

Example:

int x = 12000000;

JLabel.setText(x); 

which outputs 1200000, however I am trying to achieve on of the following.

• 1 200 000
• 1,200,000

Answer 1

If you want to use the user's locale to determine whether to use commas or decimal points, use the following:

String formattedNum = NumberFormat.getIntegerInstance().format(x);

For Americans, you would see 1,200,000.

Answer 2

You can try this:

int x = 12000000;
JLabel.setText(NumberFormat.getInstance().format(x));
