how to round a double into two decimal places in java

Comment

double notRoundNum = 231.12321

DecimalFormat df = new DecimalFormat("#.##", new DecimalFormatSymbols(Locale.ENGLISH));
// (#.## sets the number of decimal places) 
// (Decimals format symbols sets '.' as the symbol for decimals, if it's not defined like that as default)

double roundNum = Double.parseDouble(df.format(notRoundNum)); // = 123.12
