I want to conver String value into Integer, and I have this :
String timeInterval = tfInputTinter.getText();
Integer tint=(Integer.parseInt(timeInterval))*1000;
but when I put this second line, the conversion, the program stops to work. I tried also with Integer.valueOf(timeInterval) but again I had the same problem.
I am trying to convert the double 4270571936.0000000000d to a hex string using Double.toHexString() and the answer I'm getting is 0x1.fd17834p31, what does p stands for?
The answer I'm expecting to get is 0x41efd17834000000 so not sure why it won't give me the correct answer?
The following floating point Double to hex calculator shows the write answer right Floating Point to Hex Converter

View Replies View RelatedI am working on a small brain teaser project where I am taking a string input from a Scanner, and turning into ascii. The problem comes into play when the string has a space in it, so if the question is what's your name? and you say Michael Jackson, Michael gets converted then Jackson becomes the answer to the next question, rather then the second portion of the current string.
This is an older version of what I'm doing currently, but it had the same basic problem with spaces.I will say I did my current version entirely different.

//Creates a string
String favoriteFlick;
System.out.println("Enter the title of your favorite film?");

I am working on a simple online chat program. I have build the server services and generally everything works smoothly.Now for the input area i use a JEditorPane as like the output message area. The reason of choosing JEditorPane is because i want to apply some CSS on future...
Now under the input message area there are two JButtons. One for attachments and other one for emoticons. Now i am trying to make a Popup Menu with all my Emoticons Images when someone click the JButton(emoticons). I was thinking about a JList inside a popupMenu but that kind of thing is mostly impossible i guess. Any way to automaticaly convert String to images for example when someone type in inputJEditor something like this :) or this :( to convert it to emoticon image ...
I have a date in the following String format "2013-03-28,19:37:52.00+00:00" and post processing I am converting this to following String as per prevailing logic "2013-03-28,19:37:52.00+0000" (This is existing code and no changes have been Made here for last few years) And the using this SDFormat i.e new SimpleDateFormat("yyyy-MM-dd,HH:mm:ss.Sz") for conversion to Date Object
We are suddenly getting this exception now can't figured out what has changed ?
java.text.ParseException: Unparseable date: "2013-03-28,19:37:52.00+0000"

Code:
public static void main(String[] args) {
// TODO code application logic here
Calendar time = Calendar.getInstance();
int min = 1;//time.get(Calendar.MINUTE);
String blank = "0";
int checker = ((min > 10 ) ? min : blank+min);
System.out.println("The time is " + "12" + ":" + checker );
}
This is my code, as you can see, I have if the min is less than 10, display the string "0" next to it so it will be something like
blank is zero and min is one
So it will display as 01 but after min reaches 10 and above, the 0 goes away. Problem I have is, you just cant add "blank" to int checker because checker is an int and blank is a string. So what must I do in order for it to display the 0 under checker?
I've started writing a new program that Scans for some strings. I want to specify a random Integer to those Strings in order to do my desired idea. what should I do?!! my codes are here :

now I want to Specify an Integer to each person that has been scanned! for example if the first person is " David " , which is a String, in the next step :

randomNumber.NextInt(101);
int David = randomNumber.NextInt(101);

I have to make a programm where the user gives you the bank sorting code and the account number and you give him the IBAN. That was so far no problem and I was done within minutes except of one thing that I simply can't figure out even though im trying since weeks. At some point I have to convert a string to integer. My research told me its with parseInt() and I dont get a syntax error when I compile my programm (using BlueJ). But when executing the programm stops and gives me some weird bug message. Here is code and bug message:
Java Code:
public class IBAN {
public IBAN(String Bankleitzahl, String Kontonummer) {
Bankleitzahl=Bankleitzahl.replace(" ",""); // Die Leerzeichen werden entfernt
int Anzahl=Bankleitzahl.length(); // Auf der Variabel Anzahl wird die Anzahl der Zeichen von der Bankleitzahl gespeichert

View Replies View RelatedI'm having an issues with adding integer values to a string list. The question is asking me "the method should iterate over runners, and for each runner generate a random number between 90 and 180 (inclusive) which should be used to set the time (in minutes) for that runner."
I have been able to get the random number and iterating over the runner arraylist but I haven't been able to figure out how to add the values generated into the runners list. I am also using BlueJ.

View Replies View RelatedI am trying to code using error handling and I am a bit confused on how to go about doing it correctly. My code converts a string that has all numbers into an integer and the error handling should recognize that if it isn't a proper number and ask the user to try again or enter 'q' to quit.Do I place a throw new exception in the try block and put conditionals like if charAt(i) is some letter or a symbol then throw new exception?
Java Code:
import java.util.Scanner;
public class practice {
public static void main(String[] args) {
Integer finalValue = null;
boolean validValue = false;

When learning HashMaps in C++ I had to create the whole algorithm. In the code I created I could simply place a string into the method and it would store the names for me by turning the string into a integer and storing is accordingly. If there was a collision it would grow linearly at that location.
//play with Hash Tables
void getNames(String names) {
HashMap<String, Integer> map = new HashMap<String, Integer>();
map.put(names,22);
}
How can I do this in Java. I read about them and look at examples and they all for the most part look like this.
I am looking for a good and reliable library to read a string to construct a list of Integers, Doubles, Booleans, etc. This library should be robust enough to handle faulty input from an inexperienced user.
Example:
input: "1, 2, 3, 4"
output List<Integer> [1, 2, 3, 4]
input: "1, 2, 3.6, 4"
output List<Double> [1.0, 2.0, 3.6, 4.0]
input: "true, true, false"
output List<Boolean> [true, true, false]
input: "[1, 2, 3]"
output List<Integer> [1, 2, 3]
input: "(1, 2, 3)"
output List<Integer> [1, 2, 3]
It would be really nice if such a library would already exist.
