String Manipulation - Getting User ID?

Apr 17, 2014

I have a string and i need to do some manipulation with that. I have tried couple of things but not sure if those are feasible or not. Here is the situation:

uid=aa,bb,ou=people,cn=administrativeldap,cn=punit.punit.a-12-m020.20,o=ttt

I want the value of uid from this string, actually it's user id.

This particular string i want :: aa,bb

Things which i have tried:

I was trying it in this way string start with uid and ends with ou, but in this case user name itself can have ou, so in that case it breaks. Another approach i was thinking of is splitting the string by = which gives me aa'',bb,ou at first position and then i will again split this string to remove ,ou. but i am not sure if this approach is good or not?

Allow User To Input One Or More Integers And Store Them In Vector For Manipulation Later On In Program

Oct 1, 2014

I'm playing with vectors for the first time... What I'm trying to do is to allow a user to input one or more integers and store them in a vector for manipulation later on in the program... Here's the portion of the program I'm working with:

Java Code:

package com.itse2317;
import java.util.*;
public class VectorTest
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);

[code]...

My question is this: Is there any way to move from inputting integers to printing them, without entering a non-integer (for example, hitting enter)? I looked at the API for the Vector class, and either I'm not thinking about the problem the right way to be able to find an answer, or it's just not there.

String Manipulation For Program Manipulating Name Of City

Jan 23, 2015

I have to write a program that asks the user to enter the name of their favorite city and use string variable to store the input. The program should display the following:

-The number of characters in the city name
-The name of the city in all uppercase letters
-The name of the city in all lowercase letters
-The first character in the name of the city

However, I can't seem to get past the following errors;

Programming Challenge #12.java:37: error: variable cityFirstChar is already defined in method main(String[])
char cityFirstChar = city.charAt(0);
^
8 errors[CODE
----jGRASP wedge2: exit code for process is 1.
----jGRASP: operation complete.

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: ");

Take Replacement String Entered By User And Print Out New String

May 22, 2014

I'm having trouble with the last few lines of the code. It's supposed to take a replacement string entered by the user and print out the new string. For some reason it's now allowing me to enter a replacement string

import java.util.Scanner;
public class Project02 {
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
System.out.print("Enter a long string: ");
String lString = keyboard.nextLine();

[Code] ....

Output:

Enter a long string: the quick brown fox jumped over the lazy dog
Enter a substring: jumped
Length of your string: 44
Length of your substring: 6
Starting position of your substring in string: 20
String before your substring: the quick brown fox
String after your substring: over the lazy dog
Enter a position between 0 and 43: 18
The character at position 18 is x

Enter a replacement string: Your new string is: the quick brown fox over the lazy dog <------ isn't taking user input

Parallel Manipulation Of XML Files

Sep 15, 2014

I'm currently starting my thesis where my Project will involve creating a diff and merge tool for simulink slx files. These are built using several xml files, a png and sometimes some other data files. One can get to these files by changing the file extension to zip.

I am a bit troubled by this since I want to be able to handle all these files simultaneously and hence need to do this automatically when choosing the slx file.

Another Java Pixel Manipulation

Nov 21, 2014

I have a jpeg that I need to print a border around. My plan was to take the jpeg and throw it on top of a second image that is a few pixels bigger in each direction. Currently, my code prints the image with a white border on the right and bottom sides. Is there a way to print the border on all sides, and maybe even make it a more distinct color? I am not allowed to use graphics. I can only manipulate pixels. Here is the basis of my code.

public class MyArt
{
private Picture image;
/**
* Create an Art object using the jpg or bmp at the indicated location
*/
public MyArt(String filename)
{
image = new Picture(filename);

Pixel Manipulation - Create Art Object Using JPG Or BMP At Indicated Location

Nov 20, 2014

I am working on a project using pictures and am having some trouble. My assignment is to take a jpeg, and reflect it(over an imaginary x-axis so to speak). As this is my first time working with images, I am very lost. My approach was to take "pixel 0" and have it swap places with "pixel max". Theoretically, I believe I would only need to do this for the first 50% of the pixels, as each flip works on 2 opposite pixels. With my code thus far (the reflect() method), I print the left half of the image. Note: I must use pixel manipulation. I cannot use graphics.

public class MyArt
{
private Picture image;

/**
* Create an Art object using the jpg or bmp at the indicated location
*/
public MyArt(String filename)
{
image = new Picture(filename);

Making A Rectangle - Manipulation Of Instance Variables

Sep 11, 2014

I am suppose to create a rectangle and I have created two classes; Rectangle.java and RectangleTester.Java.

So far my code for the class Rentangle.java is:

package edu.sbcc.hw2;
public class Rectangle {
private int width = 25;
private int height = 25;
public rectangle(int xcoord, int ycoord, int thewidth, int theheight) {
this.width = width;
this.height = height;
}
public int getWidth() {
return width;

So for my assignment I need two instance variables for height and width for which I have, but it says in the assignment I need methods (settings and getters /mutators and accessors that allow manipulation of my instance variables which is a little confusing. Do I put these methods on Rectangle.java or RectangleTester.java.

The same goes for the calculateArea, where am I suppose to put this?

JList Manipulation - How Operating Systems Manage Processes

Sep 29, 2014

I am attempting to use JLists to complete a program that models how operating systems manage processes. A quick synopsis of what it is supposed to do. Each process is to have a priority level (I chose to do 1 -3 with 3 being the most important) and there are supposed to be three lists. One for ready processes, blocked processes, and a running process.

My issues:

1) when I block a process it does indeed switch lists but when it is copied into the blocked list it pulls the element number instead of what the actual process number is. For ex: Say the ready list has 5 processes / I delete 2 / Leaving process 1, 2, 5. When I block 5, it gets registered in the blocked list as process 2.

2) I can't figure out how to give a label to each of my scroll panels (JLists) to signify which box is ready / blocked / and running

3) My switch button - I have commented in what I need to do but don't know how I am going to do it.

Below are my files:

Main

import java.util.Comparator;
import java.util.PriorityQueue;
import java.util.Queue;
import javax.swing.JFrame;
import javax.swing.JTextArea;
public class PQueue {
public static void main(String[] args) throws InterruptedException {

Evaluating User Input For String Or Int

Jan 14, 2015

I have to take a users input. The general gist of the problem is I want to convert a decimal number entered by the user inputs into it's binary equivalent....the conversion part I know how to do.

I'm stuck at the user input phase. If the user inputs a decimal number within the correct range (lets say between 0-5000 for this example) the conversion goes ahead as planned and the program outputs on the screen the binary equivalent.

If on the other hand the user inputs a number outside of this range ... OR a String OR and empty space, an error message is given and the user is asked to try again. I don't know how to handle it if the user enters the different types...int or String.

Notation Meaning
A Ace
2...10 Card Values
J Jack
Q Queen
K King
D Diamonds
H Hearts
S Spades

String From User Not Removing Spaces

Apr 6, 2014

I'm not sure why but my infix string isn't removing the spaces. Here is the part of the code:

Scanner s = new Scanner(System.in);
System.out.println("Enter Infix express: ");
String infix = s.nextLine();
infix.replaceAll("\s", "").trim();
System.out.println(infix);
InfixtoPostfix convert = new InfixtoPostfix(infix);
String postfix = convert.toPostFix();
System.out.println("Converted Express: " + postfix);

Is there something I'm doing wrong? Here is the output when I run it:

Enter Infix expression:
(7 + x) * (8 – 2) / 4 + (x + 2)
(7 + x) * (8 – 2) / 4 + (x + 2)
Converted Expression: 7 x+ 8 – 2* /4 x 2++

Scanning Known String And Not Input Typed By User?

Jul 29, 2014

I'm having an issue with my program that needs 2 lines of input when I only want one. First I call Scan.nextLine(); to fetch a word. Then I want Scan.findInLine(word).charAt(number); to scan the string word for a letter instead of having to put another line in the console. How do I make Scan.findInLine(word).charAt(number); scan a single String instead of scanning input typed by the user?

Getting User Input From TextArea And Storing It As String Value

Jan 20, 2015

I am having trouble with getting a user input once they enter it in to a JTextArea and then storing it in to a string value. See, I wanted the user to enter an answer in to the JTextArea, and then once I store it in to a string value, I would be able to use it later. I wanted to after storing the variable to print it on to a JLabel, but nothing is showing up... Heres my code.

static String usera[]= new String [10];
for (int i=0; i< usera.length; i++) {
//These are the JTextArea names
usera[0]= Question1.getText();
usera[1]= Question2.getText();

[Code].....

I already initialized the JLabels earlier in my code, and I did not feel the need to post all my code here. This is where I am trying to get the string variable and then printing it out.

Return A String That Holds User Inputs

Apr 18, 2015

I'm working on an assignment for my Java Programming class that requires me to work with Multiple Classes.

Overview of the assignment: Create a "Database" that allows a user to input information about a College Class.

My program has three Classes:

The information that must be tracked in the Course Class is:
- Section Number
- Instructor
- Classroom
- Students (an ArrayList of class Student)

The information that must be tracked in the Student Class is:
- Name
- Major
- GPA
- Hours

The Driver class will use the main method to print the user a prompt asking for inputs, then display all of the user's inputs after he/she wished to exit the program.

I'm having no trouble with asking the user for inputs and then checking the validations for the inputs, I'm currently struggling with return a String that houses all of the user's inputs for the variables above. The information must be returned in a method called toString(). Both the Student and Course Class must have a toString() method that returns the information in the class (value of the variables), I must then call upon these methods from the main method of the Driver Class to print them back to the user.

The toString methods within the Student & Course Classes are at the bottom of the code

To Summarize: What I need to do within the toString() methods to return the values the user has inputted for the various variables? Such as.. Should I pass something through the method? Do I need the this keyboard to pass through the variable again? I just fear that I'm currently misunderstanding a very critical part of programming.

My Driver Class

import java.util.Scanner;
public class Driver {
Course courseInputs = new Course();
Student studentInputs = new Student();
public static void main(String[] args) {

[Code] .....

System.out.println("Enter your name :

Scanner st = new Scanner(System.in);

How To Compare Int To A Empty String To Input Error Message To User

I made a guess a number program but I am having issue figuring out a way that when a user enter's in nothing for the program to spit out a message saying "hey entering nothing doesn't work try again" then ask for input. I have done some research and from what I have found is to read the input in as a String rather than int, and use something like Integer.valueOf() to get the integer value but I am completely lost on how to apply that to my program here is my code

//import statements
import java.util.*; //for scanner class
// class beginning
public class Guess {
public static void main(String[] args ) {
//Declare variables area
int guess, secretNumber = (int) (Math.random() * 10 + 1), lowGuess,highGuess;
