Java add leading zeros to a number....
- by user69514
I need to return a string in the form xxx-xxxx where xxx is a number and xxxx is another number, however when i have leading zeros they disappear. I'm trying number formatter, but it's not working.
public String toString(){
NumberFormat nf3 = new DecimalFormat("#000");
NumberFormat nf4 = new DecimalFormat("#0000");
if( areaCode != 0)
return nf3.format(areaCode) + "-" + nf3.format(exchangeCode) + "-" + nf4.format(number);
else
return exchangeCode + "-" + number;
}
}
I figured it out:
public String toString(){
NumberFormat nf3 = new DecimalFormat("000");
NumberFormat nf4 = new DecimalFormat("0000");
if( areaCode != 0)
//myFormat.format(new Integer(someValue));
return nf3.format(new Integer(areaCode)) + "-" + nf3.format(new Integer(exchangeCode)) + "-" + nf4.format(new Integer(number));
else
return nf3.format(new Integer(exchangeCode)) + "-" + nf4.format(new Integer(number));
}
