I'm getting the distance in string like "8.9km". I need to convert it to float.
So if the string is "8.9km", the corresponding float will be 8.9
How to achieve this in Java?
Note: The value can change to miles/meters also, since it is retrieved from Google Maps
You can try the following code,
String dis = "8.9km";
Float distance = Float.valueof(dis.substring(0,dis.indexOf("km")));
float d = distance.floatValue();
You can do
String distance = "8.9km";
float distanceInFloat = Float.parseFloat(distance.substring(0,distance.indexOf("km")));
System.out.println(distanceInFloat);
Output :
8.9
Use following code:
String s="8.9km";
s=s.replace("km", "");
float f=Float.parseFloat(s);
System.out.println(f);
Output:
8.9
Hope it helps.
try the following for removing all non-digits(excluding '.') from a string
String distance = "7.9km";
float floatValue = Float.parseFloat(distance.replaceAll("[^\\d.]",""));
System.out.println(floatValue);
String str = "8.9km";
str = (str.replace("km", ""); //remove the km
float f = Float.parseFloat(str); //convert the string to a float
The float f will now have a value of 8.9
System.out.println(f);
Output:
8.9
Try this:
public float parse(String string, String suffix) { // suffix can be m, km etc.
if (!string.endsWith(suffix)) {
throw new IllegalArgumentException();
}
string = string.subString(0, string.length() - suffix.length()); // get rid of the suffix we have at the end
return Float.parseFloat(string); // parse the float from what we have left
}
If the float is invalid, or the string doesn't end in "km", a NumberFormatException or IllegalArgumentException will be thrown, respectively.
Try this.. i hope it will help
String km = "8.9km";
float kmInFloat=Float.parseFloat(km.replaceAll("km",""));
System.out.println(kmInFloat);
Output :
8.9

I have a string "$1,076.00" and I want to convert them in to int,
I capture some value $1,076.00 and saved in string called originalAmount,
and tried int edited = Integer.parseInt(originalAmount); and it gave me error java.lang.NumberFormatException: For input string: "$1,076.00"
can anyone help?
You need to remove the undesired part ($ sign) and then parse the string to double carefully since the decimal part is a locale dependent
String pay = "$1,076.00";
NumberFormat format = NumberFormat.getInstance(Locale.FRANCE);
Number number = format.parse(pay.replace("$", ""));
double result = number.doubleValue();
System.out.println(result);
string sourceString = "$1,076.00";
sourceString.substring(1, sourceString.length() - 1)
int foo = Integer.parseInt(sourceString);
Try this:
String amount = "$1,076,.00";
String formatted = amount.replace("$", ""); // remove "$" sign
formatted = formatted.replace(",", ""); // remove "," signs from number
double amountDouble = Double.parseDouble(formatted); // convert to double
int amountInt = (int)amountDouble; // convert double value to int
System.out.println(amountInt); // prints out 1076
String originalAmount="$1076.00";
String amount = originalAmount.replace($,"");
int edited = Integer.parseInt(amount);
Thanks everyone yr answers help me a lot
I have come up with
originalAmount = originalAmount.substring(1);
if (originalAmount.contains("$")) {
originalAmount = originalAmount.replace("$", "");
}
newOriginalAmt = Double.parseDouble(originalAmount);
System.out.println(newOriginalAmt);
pls let me know yr thoughts
I am trying to convert a string 32,646,513.32 to a double and then convert it to a string in scientific notation like this 3.264651332E7. The code below is
double amount = 0;
for (Payments payments : pvor.getPayments()) {
payments.setDocumentNumber(pvor);
amount += Double.parseDouble(payments.getAmount());
payments.setDate(new Date());
}
DecimalFormat df = new DecimalFormat("#.00");
double totalAMount = Double.valueOf(df.format(amount));
Double totalAMounts = (Double) totalAMount;
pvor.setAmount(String.valueOf(totalAMounts.doubleValue()));
How do I display large numbers in same format as I give?
Instead of using just String.valueOf(totalAmounts), which give you number in exponential format, you need to format your double value to match the string format that you want. Try something like new DecimalFormat("#,###.00").format(totalAmounts). Or simply use String.format("%,.2f", totalAMounts).
If I understood your problem correctly then you do not need String.valueOf() but String.format().
Here is the code snippet:
public static void main (String[] args) throws Exception
{
String input = "32,646,513.32";
double value = Double.parseDouble(input.replace(",",""));
String output = String.format("%f",value);
System.out.println("Value: " + output);
}
Output:
Value: 32646513.320000
Replace the following line in your code appropriately:
/* Note the change from `valueOf()` to `format()` */
pvor.setAmount(String.format("%f",totalAMounts.doubleValue()));
How do I convert String in form xx:yy into integer form xxyy or float form xx.yy
For example If I have the following string.
String x = "10:30"
How do I get integer 1030 or float value 10.30 ?
String[] parts = x.split(":");
float value = Integer.parseInt(parts[0]) + (float)Integer.parseInt(parts[1])/100;
or
Float.parseFloat(x.replaceAll(":", "."));
String xInt = x.replace(":","");
Integer.parseInt(xInt);
String xFloat = x.replace(":",".");
Float.parseFloat(xFloat);
In my android app, I am trying to convert a string value to a double value. But it throws NumberFormatException. The string value is "30.192781000000000"
My code is,
String Latitude="30.192781000000000";
double Lat2 = Double.parseDouble(Latitude.trim());
I have tried with this also,
NumberFormat nf = NumberFormat.getInstance(Locale.US); // Looks like a US format
double lat2=nf.parse(Latitude.trim()).toDouble();
But didnot work. Please suggest me any solution. I have to work with a double value and not a string value.
Thanks in advance!!
Try this Code i think this should work.
NumberFormat _format = NumberFormat.getInstance(Locale.US);
Number number = null;
try {
number = _format.parse(latitude);
double _double = Double.parseDouble(number.toString());
System.err.println("Double Value is :"+_double);
} catch (ParseException e) {
}
Thank you,
Blockquote
String latitude="30.192781000000000";
double latitude2= Double.parseDouble(latitude.toString());
that isnt valid java code. try:
String latitude = "30.192781000000000";
double latDouble = Double.parseDouble(latitude);
How can I convert a double into a String in Java for Mobile phones?
Note that this does not work:
double lat = 22.456464;
String strLat = String.valueOf(lat);
Neither does this:
String str = Double.toString(double).
I'd suggest you try
double lat = 22.456464;
String strLat = "" + lat;
There is typo in your code:
String str = Double.toString(double).
It should work this way:
String str = Double.toString(lat);
Double class CLDC 1.1 contains the method:
public static String toString(double d)
Older or more limited API may not have the method or Double class.
