Replace HTML Code With Variables From Servlet
Aug 8, 2014
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 + """);
[Code] .....

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 = "";
[Code] .....
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..

I want to extract a specific String from HTML, specifically, I want to extract a String from in between <...>
So far, I've got this
package main;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
public class HTMLGrabber {
static String allOneString = "";
[code]....
The problem I have is when I change the last parameter in this line:
System.out.println("And the Keywords are:
" +allOneString.substring(allOneString.lastIndexOf("meta name="keywords" content=") + 30, allOneString.indexOf("Fictional History">")+17));
to
System.out.println("And the Keywords are:
" +allOneString.substring(allOneString.lastIndexOf("meta name="keywords" content=") + 30, allOneString.indexOf("">")));
i.e. the generic alternative, I get this error message:
Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: -366
at java.lang.String.substring(Unknown Source)
at main.HTMLGrabber.main(HTMLGrabber.java:45)
Is there a better and simple way to extract a substring?

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 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.

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");
}
}

I 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...
