How To Extract Specific Part Of A String In Java

Mar 1, 2014

consider this statement from a jsp file(there are many more statements like this in jsp file..) Statement -

<h:dataGrid something styleclass="styleclass1" something1
onClick="event" something2
<% this is a scriplet tag %>
something3
style="style1">

<h:output text>hello i am text</h:output text>
</h:dataGrid>

What I want is to extract(and store it somewhere) the part from "<" to ">" where:

< - is the one in "<h:dataGrid"
> - is the one in "style1>" and not the('>') one that appears in the end
of "</h:dataGrid>" or "<h:output text>" or "</h:output text>"

Problem is the text b/w && is in multi-line...&& there are scriplet tags in between them.. so i don't know how to extract this particular string.. i tried using using some regular expressions but couldn't find the exact one..

(this was just an example && instead of this "" tag it can be anything like again in this line :

<h:output text>hello i am text</h:output text>

I want to extract the string from "<" till ">" where :

< - is the one in starting of "<h:output text>"
> - is the one in ending of "<h:output text>" and not the one in "</h:output text>"

However the difference b/w this example and the above mentioned one is that this one is not multi-line and doesn't contains any scriptlet tags)....

Extracting Part Of A String?

Oct 13, 2014

Okay So I am creating an application but I'm not sure how to get certain parts of the string. I have read In a file as such:

*tp*|21394398437984|163600
*2*|AAA|1234567894561236|STOP|20140527|Success||Automated|DSPRN1234567
*2*|AAA|1234567894561237|STOP|20140527|Success||Automated|DPSRN1234568
*3*|2

I need to read the lines beggining with *2* so I done:

s = new Scanner(new BufferedReader(new FileReader("example.dat")));
while (s.hasNext()) {
String str1 = s.nextLine ();
if(str1.startsWith("*2*")){
System.out.print(str1);
}
}

So this will read the whole line I'm fine with that, Now my issue is I need to extract the 2nd line beggining with numbers the 4th with numbers the 5th with success and the 7th(DPSRN). I was thinking about using a String dilemeter with | how to extract them once i've used the dilemeter.

How To Extract Values From A String

May 10, 2014

I'm looking to get two values from this string. I have tried re formatting and with little success. I read this in from a text file and then tried the below code to extract it. I have also tried

{Deposit=100.00, Fees Paid=5.00}

I am just looking to get the 100.00 and the 5.00. I tried using this code below but it separated it into Comma and put it in an array which is probably what im not looking for.

[code]
final Pattern pattern = Pattern.compile("[=st]");
final String[] result = pattern.split(st2);
System.out.println(Arrays.toString(result))
[code]

String Manipulation - Extract Substrings Consisting Of First N-4 And Last Three Characters

Feb 18, 2014

I do have a quick question about string manipulation. You see I've been given a simple exercise that involves asking the user to input a number between 1,000 and 999,999 and displaying the result. Simple enough, but the caveat is that if the user keys in the comma, say 24,000 instead of 24000 for example, the program is not to display the comma. I don't see how to do this without an 'if' statement. The book says the 'if' is not necessary but does offer this hint: "Read the input as a string. Measure the length of the string. Suppose it contains n characters. Then extract the substrings consisting of the first n-4 characters and the last three characters."

What good is n-4 going to do if the string's lengths varies?

Here's what I have written thus far:

import java.util.Scanner;
 public class P13
{
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.print("Please enter a number between 1,000 and 999,999: ");

Removing Specific Characters From A String

May 7, 2014

I just need to write a simple program/function that replaces certain letters from a string (i.e. censor( "college", "aeiou" ) returns "cllg"). I'm trying to get the code right first, and then write a function for it.I basically just thought that I would iterate over the first string, and once I had the first character, I would then iterate over the second string, to see if the character exists. I'm getting a "dead code" error on my second loop because I put the second "break."

public class ap {
public static void main(String [] args){
String s = "Hello";
String s2 = "aeiou";

Specific Regular Expression - Split A String

Mar 3, 2014

Regular expression which I want to use to split a string. The string could look similar to this:

"a = "Hello World" b = "Some other String" c = "test""

The String is read from a file where the file contents would be:

a = "Hello World" b = "Some other String" c = "test"

After splitting I would like to get the following array:

String[] splitString = new String[] {"a", "=", ""Hello World"", "b", "=", ""Some other String"", "c", "=", ""test""}

I know I could just write a simple text parser to go over the string character by character, but I would rather not do it to keep my code clean and simple. No need to reinvent the wheel.

However, I just cant seem to be able to find the right regular expression for this task. I know that a RE must exist because this can be solved by a finite automaton.

Converting String To Title Case But Ignoring Specific Word

Feb 23, 2014

I need to turn some strings from:

'1-the-high-street'
to:
'1 The High Street'

But...

if string is
'the-dog-and-duck'

I want to achieve
'The Dog and Duck'
...whereby the 'and' is NOT converted to title case

My code as follows:

String propertyPageTitle = "1-the-high-street";
propertyPageTitle = propertyPageTitle.replace("-", " ");
propertyPageTitle = WordUtils.capitalizeFully(propertyPageTitle);
System.out.println(propertyPageTitle);

prints: '1 The High Street'

How could I handle the second scenario so it does not convert 'and' to titlecase?

Swing/AWT/SWT :: Move Focus From Specific Jcombobox To Specific Jtextarea?

Nov 5, 2014

How do I move focus from a jcombobox to a specific component say a jtextarea.

My attempt below seems to be moving to a random component not the desired jtextarea.

takenByCombo.addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_TAB ) {
e.consume();
dayJTArea.requestFocus(); // focust not moving dayJTArea
}
}
});

I applied the above logic to move focus from a specific jtextarea to another jtextarea as seen below and it works as desired.

dayJTArea.addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_TAB ) {
e.consume();
monthJTArea.requestFocus();
}
}
});

Changing Value In Specific Point Of Specific Line In TXT File

Feb 9, 2015

So here we go with my problem:

- from the main class will arrive three variable (String name_used, int level_choose, int level_result)

I have a .txt file with this kind of formatting:

mario 1 1 0 1 0 1
carlo 0 0 0 1 1 0
...

Where I use 1 and 0 in the main for write if the level (you see that the numbers are always sixr? are egual to six level existing) BEFORE is done correct or wrong

- when in the main a user make a level a feedback coming back from the class level saying if the user made the count correctly or wrong. and i wanna replace the value (1 or 0) in the txt file with the new level result.

So i have all what i need as parameters i think.

name_used to look for the correct line in .txt file with .indexOf
level_choosed to go throught the correct index of that line
level_result (1 or 2) to be replaced with the existing one

Java Code:

public void salvaRisultati(String name_used, int level_choosed, int result_of_level) throws FileNotFoundException{
}
} mh_sh_highlight_all('java');

Check Specific Value From A Specific Line From TXT File

Feb 8, 2015

I have some problem to understand the way to make this:

In my main class a user can save his name in a txt file (and the system initially will add 6 value equals to 0) than he can choose between 6 level and make it.

example of .txt file data:

mario 0 0 0 0 0 0
carl 0 0 0 0 0 0

AT THIS MOMENT i just made other class and they work, is this new one that is hard for me. I'm trying to make a class that:

1- (first method called verificaRisultati) take name_used and level_choosed from the main and go to check in the .txt file if that level before was done right(1) or wrong(0)

and return something like "before you made this level properly" or "before you made this level incorrectly" AND THEN let the user start with the level.

2- (second method called salvaRisultati) at the end of the level i wanna pass the result (correct/incorrect) to another method of this class that will save the value (1 or 0) associated to the user in the right position.

This is the class that i'm writing:

Java Code:

import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
public class ResultUsers {

[Code] ....

I really need some hint and some code example because I'm stuck. How I can take exactly the line with the user name? How I can correctly split the line in an array and then read/modify the value for that level?

Add A Zero For Decimal Part

Apr 19, 2015

Add the following method to the BankAccount class: public String toString()Your method should return a string that contains the account's name and balance separated by a comma and space. For example, if an account object named benben has the name "Benson" and a balance of 17.25, the call of benben.toString() should return:

Benson, $17.25

There are some special cases you should handle. If the balance is negative, put the - sign before the dollar sign. Also, always display the cents as a two-digit number. For example, if the same object had a balance of -17.5, your method should return:

Benson, -$17.50

Here is my code:

public String toString() {
String result = name + ", ";
if (balance < 0) {
result += "-";
}
return result += "$" + Math.abs(balance);
}

My code only works in case there are full two numbers for the cents part, not for the case when there's only one number. So I wonder how I can add an extra zero when needed.I can get only the decimal part and add a zero if it's less than 10, but I don't know how I can extract just the decimal part from the number. (The balance is just a double and it doesn't have any separate field for dollars and cents).

Swing/AWT/SWT :: Extend And Retract Part Of GUI

Jul 18, 2014

I have a GUI that I've been working on for a while now. What I am trying to figure out, is a way to have the user push a button, and when they do have the GUI extend out to the right with another table to use for Filter Data. Once They are done, I want them to push that button again, and the panel with the query data retracts and is hidden again, all without changing the size of the current GUI in question. I've tried a bunch of different things with setting preferred and Minimal values to my GUI, and I've played around with different Layouts (Border Layout.East, etc), but I can't seem to find a good working solution.

Ideally it would be slick if I could make my panel SLIDE out and SLIDE back in, which would look really cool, but I'd settle for something that just worked.

JSF :: Loading Part Of Page Using AJAX - How To Handle CommandButtons

Jun 25, 2014

I have a page which lists items using a ui:repeat. The repeat is surrounded by my h:form tag.

Now I have made it so that when click an item, then I load some item details - render them in their own xhtml file and inject the result into the dom tree.

This is causing some problems.

* My injected content has commandButtons and commandLinks which do not work because I don't have a form in my injected page - since this would cause nested forms :-(
* tried to replace commandButtons and commandLinks and instead create unique url's that I can call to get my work done - but how to I then re-render a panelGroup on then page? tried using jsf.ajax.request but I'm not able to get part of the page (a shoppingcart) to update

Basic outline

<h:form>
<table>
<ui:repeat ...>
<tr><td onclick="...">Click here to load item details</td></tr><tr><td id="itemDetailPlaceholder"></td></tr>
</ui:repeat>
</table>
</h:form>
