Convert to int from String of numbers having comma

Question

I have value like this:

String x = "10,000";

I want to convert this to int.
I can convert it by removing comma like below:

String y = x.replace(",", "");
int value1 = Integer.parseInt(y);

But I don't want to do it like above.

Any other suggestions like inbuilt function? Or any other recommended ways for this?

Answer 1

You can simply:

NumberFormat.getNumberInstance(Locale.UK).parse(x);

Read about:

• NumberFormat
• Locale.UK and others.

Answer 2

Try this:

 NumberFormat format = NumberFormat.getInstance(Locale.US);    
 Number number = format.parse("10,000"); 

 // Now you can get number values from the object (like int, long, double)
 System.out.println(number.intValue()); 

Output:

10000

Note: If you string contains values after decimal point, you need to use number.doubleValue to retain the precision because number.intValue() will simply ignore values after decimal points.
