Replace Value Of Delimiter In String
Jan 8, 2014How can I change the value of
String str = "1234|U||45|||"
into
String str = "1234|U| |45| | |"
How can I change the value of
String str = "1234|U||45|||"
into
String str = "1234|U| |45| | |"
Working on my java skills. The is Delimiter function is suppose to return true if there is a delimiter in the string and false otherwise. The main is suppose to call this function and count the number of words in the string:
Here is what I came up with:
import java.util.*;
public class NumberOfWordsInString {
public static void main (String[] args){
Scanner in= new Scanner (System.in);
String s;
[Code] ....
Somehow my method isn't being successfully called by my main and the following error msg was received:
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
length cannot be resolved or is not a field
The method isDelimiter(char) in the type NumberOfWordsInString is not applicable for the arguments (char[])
at javaimprovements.NumberOfWordsInString.main(Number OfWordsInString.java:10)
line 10:
char ch [] = new char [s.length];
and the main doesn't call the isDelimiter function
I have the the string value similar to the one which i have to split based on the delimited ","
String SampleString=" 'ab,c', 'xyz', lm,n,o "
I know I can easily call split function which will eventually split the above string. But in my case the delimiter "," , is also a part of the string. If I call the function SampleString.split(',') I will get the output as listed below
ab
c
xyz
lm
n
o
but the expected output is
abc
xyz
lmno
My interest in Java leads me to try and print numbers from 1-100. The output should show all numbers from 1-100 and each number that is divisible by by 13 should be replaced with a string "Fuzzy".
public class Fuzzy {
public static void main (String[]args){
for(int i = 0; i < 100; i++)
if(i % 13==0)
System.out.print(i + "fuzzy");
}
}
how to replace all the command that is found on a string between 2 double quotes? for example I have a text file that contains data like as following
A,"-16,12","-178,245","-15,506"
B,"-16,12","-178,245","-15,506"
C,0, 0,1
I need an output like this:
A,"-16.12","-178.245","-15.506"
B,"-16.12","-178.245","-15.506"
C,0, 0,1
I did this but without regular expression. It seems to me that a regular expression it's more elegant than to parse every line and replace it.
The problem is i want to replace some string text with foreign characters, but JTextArea returns plainText.
For Example:
str = new String();
str.replace('e', 'é');
textArea.setText(str);
but textArea returns plainText.
This is my input from my text file: 1|John Jay Smith|1985-01-10|2010-05-10|2014-03-05|212-222-2233..So, I have to convert 1 to integer. Break John Smith into first name as John and Middle name as Jay Last name as Smith.If no middle name is given then first is John and Last is Smith . Read 1985-01-10 as a date value . 2010-05-10 as another date value which could be null. 2014-03-05 as another date value which could be null. and at last 212-222-2233 as phone number.
Scanner sc = new Scanner (inFile);
sc.nextLine();
while (sc.hasNext()){
String row= sc.nextLine();
I want to read this line of input and assign the value accordingly.
I have a text file that has contents as follows:
testing1,true,0,0.0,0,0.0,4.0,0.0,0.0,0.0,0.0
test2,true,0,0.0,0,0.0,4.0,0.0,0.0,0.0,0.0
I am trying to read only the first item in each list using a comma as a delimiter using the following code.
public String[] pList() {
ArrayList<String> names = new ArrayList<String>();
String word;
try {
String path = P_FOLDER + P_FILE;
[Code]....
I am testing some stuff here is my code:
public static void main(String[] args) {
String[] a = new String[5];
//String input = JOptionPane.showInputDialog(null, "enter input");
Scanner scanner = new Scanner(System.in);
[Code] ....
I am trying to type in 5 strings from java console and print them all out. I am using a "/" as a delimiter. My problem is that it does not print any output after I type strings separated by "/" like this: hello/gea/cae/eaf/aer and press enter. It works if I use JOptionPane but from the console its not working. I want to use the console instead of JOptionPane for this one.
I have a header in file like below:
EMP_ID|EMP_NAME|DEPARTMENT|SALARY|ACTIVE1
passed to a string
String test = "EMP_ID|EMP_NAME|DEPARTMENT|SALARY|ACTIVE1";
I have to check if the header has only alphanumeric and pipedelimiter is allowed.
Other than these i need to raise an error.
I can't figure out why my code doesn't work. My task is to replace for example ä=>ae, using this method String.charAt(int index). So here is my code:
public class pich {
public static void main(String[] args) {
String text = "Die süße Hündin Leica läuft in die Höhle des fülligen Bären "+
"Iliyan (ein Übergrößenträger), der sie zum Teekränzchen eingeladen hat."+
" An ihrem Öhrchen trägt sie modisch eine Ähre.";
String textOhneUmlaute = "";
[Code] ....
when I launch my code I get the same String and nothing has changed
How do you replace negative zero value with a zero value when Printing results:
I want to remove the minus sign in -0.0000 and instead have 0.0000.
I am Printing coordinates and I do not want to have negative zero.
the coordinates are defined as double.
System.out.format(java.util.Locale.US," %.4f %.4f %.4f %.4f%n"xCur ,yCur,xNext,yNext);
0.0000 1.0000 -0.0000 0.0000
Basically, I am trying to write a method that will take a string, a target, and a replacement (a replacement function like string.replace). I want it to replace all instances of target with replacement EXCEPT for instances that occur within single or double quotes.
Example input / output:
this "Wont" be " replaced, be"
call: replace(theString, "replaced", "narf") and replace(theString, "be", "rafn")
output:
this "Wont" rafn " replaced, be"
I am trying write a program that accept an input and present the input with every 5th character replaced with X (count spaces also).
For example:
input: "hello my name is mario"
outpu: "hellX my Xame Xi maXio"
I only manage to replace specific letters, e.g every "m" letter.
I will like replace this code:
// boucle pour les fractions aleatoires
for (i=0; i<2; i++) {
// Creation des fractions aleatoires
Frac first = new Frac(r,5);
Frac second = new Frac(r,5);
[Code] .....
But when I use a switch case I do not have the same result as my four loops.
I have a 2D arraylist, named as adjLists, which contains arraylists, containing values like these. Each two values are a "pair" and each third is a "flag" for the pair.
[278, 106, 0, 397, 36, 0, 59, 208, 0, 366, 221, 0]
[366, 221, 0, 397, 36, 0, 132, 390, 0, 278, 106, 0, 295, 0, 0]
I use code above to search for specified value pairs in these lists. vertexnum is the number of "sub arraylists" in adjLists.
for (int l = 0; l < vertexnum; l++) {
if (adjLists.get(l).get(0) == p.x && adjLists.get(l).get(1) == p.y) {
for (int h = 0; h < adjLists.get(l).size(); h += 3) {
for (int g = 0; g < vertexnum; g++) {
if ((vertexSprite[g].getX() + vertexSprite[g].getWidth() / 2) == adjLists.get(l).get(h)
[Code] ....
This code is to search exact values and replace their flag in every occurences. It can not find all the occurences of the values/pair in the lists, it replaces flag value only a few time. Value of score should be incremented with plus 1 after each found occurence, but this code increments it more than the number of matches.
I'm trying to figure out the correct way to replace number into letter. In this case, I need two steps.
First, convert letter to number. Second, restore number to word.
Words list: a = 1, b = 2, f = 6 and k = 11.
I have word: "baafk"
So, for first step, it must be: "211611"
Number "211611" must be converted to "baafk".
But, I failed at second step.
Code I've tried:
public class str_number {
public static void main(String[] args){
String word = "baafk";
String number = word.replace("a", "1").replace("b","2").replace("f","6").replace("k","11");
System.out.println(word);
[Code] .....
Result for converting to number: baafk = 211611 But, result for converting above number to letter: 211611 = bkfk
What do I miss here?
How to distinguish if 11 is for "aa" and for "k"? D
I have a coauthorship network and I want to replace the authors names with numbers.Part of my datadet:
1992,M_DINE,R_LEIGH,P_HUET,A_LINDE,D_LINDE
1992,C_BURGESS,J_CLINE,M_LUTY
1992,M_DINE,R_LEIGH,P_HUET,A_LINDE,D_LINDE
1992,F_ZWIRNER
1992,O_HERNANDEZ
...
I want the result to be sth like this:
1992 1,2,3,4
1992 5,67
....
and a table of mappings
M_DINE 1
R_LEIGH 2
P_HUET 3

I give my dataset in csv (or text) format to my program but it says "(The system cannot find the file specified)" even though the file exists.
what should I do?
here is my code:
Java Code: public class ReadCSV {
HashMap<String, Integer> authorList = new HashMap<>();
File file = new File("d:/Course/thesis/predict/whole.scv");
int authorCounter = 0;
public static void main(String[] args) {
ReadCSV obj = new ReadCSV();

I was reading a book and came across this while loop.
public class Powers {
public static void main (String [] args){
int e;
int result;
for(int i = 0; i < 10; i++){
[Code] .....
This loop presents the following (I'm sure it's not necessary):
2 to the 0 power is 1
2 to the 1 power is 2
2 to the 2 power is 4
2 to the 3 power is 8
2 to the 4 power is 16
2 to the 5 power is 32
2 to the 6 power is 64
2 to the 7 power is 128
2 to the 8 power is 256
2 to the 9 power is 512
I am just having a difficult time understand and grasping this concept. My main issue is result *=2; this is making it very difficult to understand. How is result being replace if it only equals to 1.
This is my code:
JDialog dialog = new JDialog();
dialog.setSize(400, 150);
dialog.setTitle("Input dialog");
dialog.add( new JLabel("simtime(min)") );
dialog.add( new JLabel("interval(sec)") );
dialog.setVisible(true);
The problem is that the two lables replace each other.How to position them where we want?

How to distinguish if 11 is for "aa" and for "k"? Do you have any solutions or other ways for this case?
I am trying to custom graphic class..,My task is to replace the specific area color of the image when i select the area & pick the color..,If i choose the hand / body of the T-shirts means the color can change by the user..,
View Replies View RelatedI am wondering if there is something similar to the "Find and Replace" action, that we use in applications like Eclipse and MS Word, that is actually built into the Java API so we can use it in our code, mainly for method names?
For example, right now I have these couple of lines
rotateLeftCounterClockwise(1);
rotateBottomClockwise(1);
rotateLeftClockwise(1);
//and
rotateRightCounterClockwise(1);
rotateBottomCounterClockwise(1);
rotateRightClockwise(1);
that does one operation for a side of Rubik's cube. However, all other sides of the cube can use these same exact code with the exception of the 2nd word, ie the position, in each method.
So for example, another side would do something, like, lets say
rotateFrontCounterClockwise(1);
rotateBottomClockwise(1);
rotateFrontClockwise(1);
//and
rotateBackCounterClockwise(1);
rotateBottomCounterClockwise(1);
rotateBackClockwise(1);
The reason why I ask this is because this would DRASTICALLY shrink the size my code, rather than have to create separate methods for each operation. Now I know there is a Find and Replace feature for Strings, but I am not sure about method names...
I'm trying to replace html code with variables from a servlet. Lines with a * won't replace.
String t = screen_configedit.replace( "value="eID"", "value=""+ eid + """);
t = t.replace("value="cID"", "value=""+ cid + """);
t = t.replace("<!-- <br><font color="red">ERROR! Please contact support!</font> -->", "<br><font color="red">ERROR! Please contact support!</font>");
t = t.replace("value="status"", "value=""+ status + """);

My question is related to combo boxes. A combo box in general is a text field with a dropdown list. I would want to know if we can replace hthe dropdown List by an other component, for example a JTable component.
View Replies View RelatedI want to do a simple search and replace regular expression of lines. I am very unfamilar with Java regular expressions, and I'm not sure how to do something as simple as what I want to do. I have lines that look like this...
Java Code : access_log /home/%USER%/access_log mh_sh_highlight_all('java');
I want them changed so %USER% changes to a string, such as "cyrus," so they appear like this ...
Java Code: access_log /home/cyrus/access_log mh_sh_highlight_all('java');
The reason I want to use regular expressions is because I want to use the replaceAll method of the java.lang.String object. If I use replace I have to convert my strings into char arrays, and my code becomes bulky.
