Removing Newline And Tabs From A String

Feb 28, 2007

I have a string from which I need to remove all of the newlines, tabs, and spaces. Here is the code I wrote:

inputString = inputString.replaceAll(" ", "");
inputString = inputString.replaceAll("
", "");
inputString = inputString.replaceAll(" ", "");

It removes the spaces just fine but not the newlines or tabs. How can I do this?

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";

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++

Tokenize A String - Removing Numeric From A TreeSet

Nov 23, 2014

I am using a TreeSet to tokenize a string. The output is sorted with numeric first followed by words

E.g. 13 26 45 and before etc.....................

Is there a tidy way to remove the numeric?

Last bit of my code is :-

// print the words separating them with a space
for(String word : words) {
System.out.print(word + " ");
}
} catch (FileNotFoundException fnfe) {
System.err.println("Cannot read the input file - pass a valid file name");

Removing Item From String Array - Null Pointer Exception Error

Question 1: I am working on an assignment where I have to remove an item from a String array (see code below). When I try to remove an item after entering it I get the following error "java.lang.NullPointerException." I am not sure how to correct this error.

Question 2: In addition, I am having trouble figuring out how to count the number of occurrences of each string in the array and print the counts. I've been looking at other posts but they are more advanced and I have not yet learned how to use some of the tools they are referring to.

private void removeFlower(String flowerPack[]) {

How To Write Newline In File Using ByteArray

Jun 11, 2014

I want to write byteArray in file from String and if "/n " newline comes in String it should write from next line in file. I tried and no content starts from newline in file.

Suppose String s= "This is my Java Program /n Converting string to byteArray";

Output in file should be as :

This is my Java Program
Converting string to byteArray

When i am converting byteArray in String, it showing me same output as i wants but not in file.it showing me on console.

psvm(String arr[]){
String s= "This is my Java Program
Coverting string to byteArray";
FileOutputStream fos = new FileOutputStream("filepath");
fos.write(s.getBytes());
fos.close();
}

output in file : This is my Java Program Converting string to byteArray

Any other way to get content after newline in next line.

Opening Multiple Tabs

Sep 27, 2014

I'm now working more and more on the go and although I can carry my Macbook Air without too much trouble I've just been given an iPad Mini by work and it's far easier to do what I do with that on the move.

For work I need to open around 35 different websites at one time 4/5 times a day on the move.

With my Macbook that's no issue, as I can just use the open all function of my bookmarks, but on the iPad there is nothing that will allow me to do this.

I have looked online and a few people have had this issue and fixed it using the below Java method:

Creating a link that when clicked sets off a Javascript function that contains several window.open("url"); Clicking the link opens each website in its own tab.

JSF :: Primefaces / Creating Custom Tabs In TabView?

Nov 5, 2014

how to use a Primefaces TabView for input.

I have found this link that implements the behaviour of the TabView. It basically says to make my own Tab model.

But I want each tab to contain something like this:

I tried adding the inputTexts in my Tab model but it doesn't work, I guess I was way too optimistic :P

The only reason I want this is because I don't know how many tabs I need. It's totally dynamic, the number of Lectures is added on demand.

Simple Code In Java That Replace All Tabs User Input With Asterisk

Feb 13, 2015

I am creating a simple code in Java that replaces all tabs the user inputs with '*'. However, I am doing something wrong and I am not sure what. Here is what I have so far in Eclipse..

import java.util.Scanner; 
public class ReplacingTabs {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
String s = "";
String s2 = "";

There is an error with the s2 in the line String s2 = s.replace(' ','*');

I think I need to add String s2 to the loop but I am not sure how..

Removing A Key From Hasmap Within Hashmap

Dec 1, 2014

SO my current code creates a graph with vertices and weighted edges. This data is stored in a hashmap. The key of the hashmap is the vertex and the value is a second hashmap. This second hashmap contains the edges with the vertex it connected to as the key and the weight as the value. My current problem is that when i try to remove vertices they are removed from the key set but they stay in the value(the second hashmap) as the key for that hashmap. IS THERE A WAY TO REMOVE THE VERTEX FROM THE KEYSET OF THE SECOND HASHMAP.

Code is as follows

constructor{
adjacencyMap = new HashMap<V, HashMap<V, Integer>>();
dataMap = new HashSet<V>();
}
removal method{
if(dataMap.contains(vertex)){

Removing Elements From ArrayList

Aug 24, 2014

Referring Code 1, the book says line 16 of the code removes the element "Three" but line 17 does not remove the element "Four" because of Statement 1. The question is does remove(Object o) method invoke the == or the equals method because statement 1 and 2 seem to be in conflict

Statement 1:

Two objects are equal if their object references point to the same object. (which is nothing but definition of ==)

Statement 2:

The author refers to Statement 1 and says "As mentioned earlier, the method remove compares the objects for equality before removing it from ArrayList by calling method equals."

Java Code:

import java.util.ArrayList;
public class DeleteElementsFromArrayList {
public static void main(String args[]) {
ArrayList<StringBuilder> myArrList = new ArrayList<>();
StringBuilder sb1 = new StringBuilder("One");

list.add("aaa");
list.add("brr");

Removing Unwanted Elements In Array

for (int i = 0; i <= 99; i++){
anArray[i] = i + 1;
System.out.println(i + ": " + anArray[i] + " ");

My aim is to generate a lists containing 1 to 100. I will then count the number of integers divisible by 3. After doing so, I want to delete the integers that are NOT divisible by 3 in the lists. I tried doing it, but I seem to keep on getting the same lists.

Removing (Integer) From A Generic List?

Oct 3, 2014

I am working on a java program that is called OrderedVector which is basically a storage or list that grows and shrinks depending on the amount of data is put in. Most of the methods in my code are correct and working, the only real issue I have lies with either the remove(E obj) method or remove(int index) method. This is the driver I am currently using to test my remove method,

public class Tester {
public static void main(String[] args) {
OrderedListADT<Integer> v;
v = new OrderedVector<Integer>();
for(int i = 0 ; i <= 9; i++){
v.insert(i);

[code]....

the output I am receiving is

Removing 0
Size of data structure is 9
Removing 1
Size of data structure is 8
Removing 2
Size of data structure is 7

[code]....

As you can see, when I am calling the second for loop, none of the elements are being removed by my methods but the first for loop is working just fine.

Here is my code for the OrderedVector

package data_structures;
import java.util.Iterator;
import java.util.NoSuchElementException;
public class OrderedVector<E> implements OrderedListADT<E>{
private int currentSize, maxSize;
private E[] storage;
public OrderedVector(){
currentSize = 0;

[code]....

So overall, my remove method should implement binary search and remove elements using either an index or the object value type.

Removing Negative Number From Array

Jul 20, 2014

Ask the user to enter a sequence of at most 20 nonnegative integers. Your program should have a loop that reads the integers into an array and stops when a negative is entered (the negative number should not be stored). Invoke the average method to find the average of the integers in the array (send the array as the parameter).

how can I remove the negative number from the array and calculate the average of the posive elements without the negative ones? This is my code so far...

import java.util.Scanner;
import javax.swing.JApplet;
public class Parameters
{
//-------------------------------------
//Calls the average and minimum methods
//with different numbers of parameters
