Program Is Working But String Index Out Of Range Error

Sep 5, 2014

My Computer Programming teacher has given the class a problem that requires the use of var.charAt(), var.length() and while/for. Basically, the problem is that we have to create program that'll show a mirrored or reverse version of the entered word. Like for example, if your input is the word "Hello" (the quotation marks aren't included), the output will be "olleH".

Here's the code:

import java.io.*;
public class StringMirror
{public static void main (String [] args) throws IOException
{BufferedReader scan = new BufferedReader (new InputStreamReader(System.in));
String enteredWord = "";
int lengthOfTheWord = 0;
int lengthOfTheWordMinusOneVersion = 0;

[code]....

It is working, but the problem is that after the output, there's this error that says String index out of range: -1.

the program is working but I kind of wanted it to have no errors in the end.

Unable To Match Input String With Range Of Values And Getting PatternSyntaxException

Jun 12, 2014

I am trying to match the input string with range of values and getting PatternSyntaxException. below is my code

public static void main(String[] args) {
String regex="01[4-6]";
String code="015";
boolean bool=code.matches(regex);
System.out.println(bool);
}

output: true

But when i try to give range in double digits, it throws exception. What if i have to match a number(as string) between 10 to 25 or like that.

public static void main(String[] args) {
String regex="0[14-16]";
String code="015";
boolean bool=code.matches(regex);
System.out.println(bool);
}

Output:

Exception in thread "main" java.util.regex.PatternSyntaxException: Illegal character range near index 5
0[14-16]

Printing Out String Out Of Index?

Jan 24, 2014

I am writing a Java permutation program, it takes in N and k and gives k amount of combinations based on N length.

That portion works, but the portion I have that does not work is when k is greater then 1, the array is then then printing strings out of index.

The perm algorithm ends on index - 1 for moving characters but then I push all those characters into an Array List, I would think I could print them off however I want from there but that is not the case. I'll include the minimum amount of code possible.

//permString = 1234 or something, it doesn't matter
//Use Case N = 4 k = 3, prints out 123,124,132,134 ect
//Use Case N = 4 k = 2, error index out of range but only on the printing function; the perm function doesn't take k and
//is based on length
//the "" is just an empty string
permNow("", permString);
}

How To Avoid String Index OutOfBounds Exception

Feb 16, 2015

The method I am trying to successfully write is startsWith(String s1, String s2)

The intention of the code is to return true if s2 starts with the string s1, and false otherwise. For example,

x.startsWith("Maplestory","Maple"); Should return true.

This code partially works, depending on the values entered into it. When it is supposed to return true, it does do this. When it is meant to return false, I get a StringIndex OutOfBounds Exception.
 
public class CC02{
String remove1(char c, String s){
String to_return="";
while(true){
if(s.equals(""))
return to_return;

[Code] ....

The method I have written uses one other method from my code, which is "reverse". Any way to return false without getting this error.

Error - Formatting Output String

Sep 28, 2014

I have this error that keeps coming up any time I select one of my buttons. It actually doesn't hinder the performance of the project, everything works. But I am concerned I missed something and errors are never a good sign.On a slightly different note, I would like to figure out what the best way to format my output would be? I would like it to display as "100.00 F". I have a couple ideas on how to get the F symbol (or other symbol) by inserting something like

String degreesymbol = "F" or whichever it is and then returning that in the output string later. I can't get the decimal formatted correctly and I don't know how to print the degree symbol.Here is the code

import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.text.DecimalFormat;

EJB / EE :: Error - Literal Does Not Match Format String

Mar 3, 2015

I'm trying to insert some data of type date into database table using hibernate.i take the input date from an xhtml form as shown below

addEvent.xhtml
Event Date (dd-mon-yy) :
<br/>
<h:inputText id="eventdate" value="#{eventBean.eventDate}" p:required="required"
p:type="date"/>
<p/>
<h:commandButton value="Add Event" actionListener="#{eventBean.addEvent}" />

This is my addEvent method in EventBean.java

public void addEvent(ActionEvent evt) {
uname = Util.getUname();
boolean a = EventDAO.add(this);
if ( a) {
message = "Event has been added!";

[Code] ....

While executing this..i get the following error: ORA-01861: literal does not match format string. Could it be due to any mismatch in date format (chrome browser automatically takes date in the format mm-dd-yyyy )? If yes, how do I resolve it? (I'm using Oracle database)
