Java String Cut

May 9, 2014

If I am given a string such as:
REG20140509-0001

I want to cut out the year/month/day, so in this case '20140509'.I know that the characters in front of the date will always be letters, not numbers, but I don't know how many. Three in the above example, but could be more or less.i do know that the date will always be followed by a dash and four digits.

C Buffer To Java String

Sep 4, 2014

Due to compatibility reasons, I need to be able to store a random C buffer inside of a Java String. THis means that the Java String should contain the exact same buffer information (i.e. byte sequence) as the original C buffer. How would I do that?

All the functions I found will always somehow code/decode the C buffer, and modify its content depending on the selected encoding.

I need to do this inside JNI. Following is what I have:

Java Code:

unsigned char* cBuffer=getCBuffer();

// Transfer the C buffer to s:
jstring s=NULL;
if (env->EnsureLocalCapacity(2) >= 0)
{
jbyteArray bytes = env->NewByteArray(signalLength);
if (bytes != NULL)

[Code] ....

Split A String In Java Using Delimiters

Aug 30, 2014

I have a String as follows: "the|boy|is|good"

now, I want to split this string using the "|" delimeter.

I tried this :

String line = "the|boy|is|good";
line.split("|");

But it didn't split it. Is there some regex for "|"?

Java String Regular Expression

Apr 17, 2014

I have written below regex for two lines.

String LN1Pattern = "^((?=.{1,35}$)(/([A-Z]{1,5})(|(//[a-zA-Z0-9]+))))$";
System.out.println("/ABC//FGhiJkl012345".matches(LN1Pattern));
 
String LN2Pattern = "^(|((s+(//[a-zA-Z0-9]{1,33})){1,2}))$";
System.out.println("".matches(LN2Pattern));

s+ is a newline character.

But when I combines both as below, its not giving me expected result.

^(((?=.{1,35}$)(/([A-Z]{1,5})(|(//[a-zA-Z0-9]+))))(|((s+(//[a-zA-Z0-9]{1,33})){1,2})))$

For string "/ABC//FGhiJkl012345

//abCD01EF02" - returns False. Expected is True

I think there is some problem in lookahead placed.

Storing And Scanning String In Java?

Jun 10, 2014

I am building an app, where I have to store the data eg: "hello ! how are you" in java as a string and then use scanner to get input and check if the entered word is present in the line stored. If it is stored then the entire sentence must be displayed. eg : if the stored string is "hello how are you"

if the entered string is "how", then the entire sentence "hello how are you" should be displayed.

I/O / Streams :: Java Streaming Big String

Aug 27, 2014

I have a very big string that I am returning from servlet to javascript. I am using PrintWriter.

PrintWriter out = response.getWriter();
out.print(bigString);

But as the string is very big my code is not working. My browser just hangs.

Also is it possible to stream the output? i.e instead of sending entire string, can I send small part of string at a time. So that my browser will not hang. I don't want to handle streaming manually I am just looking for an IO class which will do the streaming automatically.

NumberFormat To Java String Format

Mar 6, 2014

In the Employee's toString, you are using the NumberFormat class to format your hourly rate and weekly pay but you are supposed to use java string formatting only (%f). You should change those to use only string formatting - no use of NumberFormat.

package coursework;
import java.text.NumberFormat;
public class Employee {
private String firstName;
private String lastName;
private int employeeId;
private double hourlyRate;
public Timecard timeCard;

Java String IndexOf Parsing

In the code below I am splitting the String relativeDN at the "," character. After splitting the String I need to parse the string from the "=" character using indexof and then rebuild the string. I was able to parse the first = sign then rebuild the string but it doesn't remove the subsequent = character. I am trying to parse the string using idexof for all the "=" characters and then rebuild it using StringBuilder. 
 
public class StringTestProgram {

Appending String To A Text File In Java?

Apr 4, 2015

I am at a loss when it comes to appending Strings to a text file in Java. I was tasked (yes, homework) to complete a program that does the following simple things:

Print out the contents of a text file to the user (got that!)

Ask the user if the want to add any customers to this text file (got it!)

Add those customer's name's, addresses, postal codes and cities. (got that too)

Verify the postal code is in the proper format (yep!)

Add the new information to the text file, and display it to the user (Nope...)

The program is, essentially, supposed to keep track of the user's customers, and store this information to a text file. However, when I run the following code, I get a number of errors:

static String firstOutput, name, address, city, postalCode, file = "";
static int customer = 0;
static String fileLine = "";
public static void main(String[] args) throws IOException {
file = "C:UsersOwnerDocumentsDiscountFly.txt";

[Code] .....

The errors I get are:

Java.io.exception. Main. Stream closed
ensureOpen (115)
ava.io.BufferedReader.readLine(BufferedReader.java:310)

I understand that the numbers correspond to lines of code (line 115, or 310, for example) but I am unsure of how to fix these errors.

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)....

Create A Java Program That Accepts A String

Feb 19, 2014

So basically I have to create a java program that accepts a string and does the following:

1.) Insert a blank space before capital letters
2.) Convert any capital letters into lower case except the first letter(if it is capital).

So if the user enters "HiMyNameIsJohn", the result should be "Hi my name is john". I am having problems inside my changeMe method. Everything works fine including putting a blank space in between upper case words. So from the previous example, my code would show "Hi My Name Is John". I am having issues making the code to convert the upper case letters into lower case. Im pretty sure the code should be right after the str.insert(i, " "). But I do not how to code it. Ive thought about Character.toUpperCase(ch); but doesnt work.

Java Code:

import java.util.*;
public class WordSeparator
{
public static void main(String[] args)
{
String word1, word2;
Scanner userInput = new Scanner(System.in);

[code]....
