How can i insert a decimal point into either an integer or a String(probably a String), 2 decimals from the right? like with money?
You can construct a stringbuffer from the string you want to modify, then use the insert method to insert a "." in the desired place. Then use the stringbuffer's toString() method to convert it back to a string. You can't put decimals in integers.
I've had a look at that class and thank you its exactly what im looking for but what syntax would i use to insert 2 from the right? i cant find it in the api
like String length and then -2?
Why don't you just use the package ......
then use this in the body.......
NumberFormat money = NumberFormat.getCurrencyInstance();
lastly print out in the body .......
Idk if this is what you were looking for, but this is a very simple version of getting the 2 decimal places.
You could do as mentioned above (use the number format class).
However you could also do this using String functions (length, and substring)
int length = inputString.length(); String beforeDecimal = inputString.substring(0,length - 2); String formatted = beforeDecimal + "." + (inputString.substring(length - 2));
