how update Jtextfield text simultaneously when typing on it? - java

I have a JTextField.I want after each character the user types,a method call and change the order of character in same JTextField,but in my code displayArrestNo2() method call and print in consol right answer but dont update content of JTextField.How can do it?
public static void main(String args[]) {
final JTextField textField = new JTextField();
textField.setSize(100, 100);
textField.getDocument().addDocumentListener(new DocumentListener() {
public void changedUpdate(DocumentEvent e) {
}
public void removeUpdate(DocumentEvent e) {
}
public void insertUpdate(DocumentEvent e) {
try{
Stringx=displayArrestNo2(e.getDocument().getText(0,e.getDocument().getLength()));
System.out.println(x);
}catch(Exception ex){
ex.printStackTrace();
}
}
public void warn() {
}
public String displayArrestNo2(String aValue){
System.out.println("oroginal value: " + aValue);
aValue = " "+aValue+" ";
System.out.println("space added value: "+aValue);
final String validStr = " ابپتثجچحخدرزژسشصضطظعغفقکگلمنوهیي";
int lPos, fPos, i, j, k;
boolean flgEnterIntSection, lastWasChar;
String result = "";
flgEnterIntSection= false;
lastWasChar = false;
lPos = 0;
i = aValue.length()-1;
while( i >= 0) {
char[] aValueArr = aValue.toCharArray();
/* char[] tmpArr = aValue.toCharArray();
char[] aValueArr = new char[tmpArr.length];
for(int x=0; x<tmpArr.length; x++)
aValueArr[x]= tmpArr[tmpArr.length-x-1]; */
if (aValueArr[i] == 'ß')
aValueArr[i] = '˜';
if (convert(aValueArr[i]) == -1)
{
if(validStr.indexOf(aValueArr[i]) > 0)
{
j = 0;
while ( ( (i - j) > 0) && (validStr.indexOf(aValueArr[i-j]) > 0 ))
j = j + 1;
if (j >1)//j>1
{
k = j;
while (j > 0)
{
result = result + aValueArr[i - j+1];//i-j+1
j--;
}
i = i - k+1;//i-k+1
}
else
result = result + aValueArr[i];
}
else
result = result + aValueArr[i];
i--;
flgEnterIntSection = false;
}
else
{
fPos = i;
j = i;
while ((j >= 0) && ((!flgEnterIntSection) || (convert(aValueArr[j]))!=-1))// (StrToIntDef(AValue[j], -1) <> -1)
{
flgEnterIntSection = true;
while ((j >= 0) && (convert(aValueArr[j]))!=-1) // StrToIntDef(AValue[j], -1) <> -1)
j--;
if ((j > 0) && ((aValueArr[j] == '.') || (aValueArr[j] == '/')) )
if (((j-1) >= 0) && (convert(aValueArr[j-1]))!=-1) //StrToIntDef(AValue[j - 1], -1) <> -1)
j--;
}
lPos = j + 1;
for (j = lPos; j <= fPos; j++)
{
result = result + aValueArr[j];
}
i = lPos-1;
}
}
// return result;
// System.out.println("before reverse "+result);
return reverseOrder(result);
}
String reverseOrder(String input){
String [] inArr = input.split(" ");
String reversed = "";
for(int i = inArr.length-1; i>=0; i--){
reversed += inArr[i] + " ";
}
return reversed;
}
public int convert(char ch) {
try {
int m = Integer.parseInt(String.valueOf(ch));
return m;
} catch (Exception e) {
return -1;
}
}
TestJTextField x=new TestJTextField();
x.add(textField);
x.setVisible(true);
}
in insertUpdate() method ,displayArrestNo2() is called per character but dont change content of JTextField.

Textfield JavaFX with dynamic mask for monetary values (Using TextFormatter)

i'm using TextFomater to make my TextField as a dynamic monetary textfield, using the following code:
public class MoneyTextFieldOperator implements UnaryOperator<TextFormatter.Change>
{
final char seperatorChar = '.';
final Pattern p;
int length;
public MoneyTextFieldOperator(int length) {
this.length=length;
this.p = Pattern.compile("[0-9. ]*");
}
#Override
public TextFormatter.Change apply(final TextFormatter.Change c) {
if (c.isContentChange() && c.getControlNewText().length() > length) {
return null;
}
else {
if (!c.isContentChange()) {
return c;
}
final String newText = c.getControlNewText();
if (newText.isEmpty()) {
return c;
}
if (!this.p.matcher(newText).matches()) {
return null;
}
final int suffixCount = c.getControlText().length() - c.getRangeEnd();
int digits = suffixCount - suffixCount / 4;
final StringBuilder sb = new StringBuilder();
if (digits % 3 == 0 && digits > 0 && suffixCount % 4 != 0) {
sb.append('.');
}
for (int i = c.getRangeStart() + c.getText().length() - 1; i >= 0; --i) {
final char letter = newText.charAt(i);
if (Character.isDigit(letter)) {
sb.append(letter);
if (++digits % 3 == 0) {
System.out.println("digits : "+digits);
sb.append('.');
}
}
}
if (digits % 3 == 0) {
sb.deleteCharAt(sb.length() - 1);
}
sb.reverse();
final int length = sb.length();
c.setRange(0, c.getRangeEnd());
c.setText(sb.toString());
c.setCaretPosition(length);
c.setAnchor(length);
return c;
}}
And calling it as follow :
montantTextField.setTextFormatter(new TextFormatter(new MoneyTextFieldOperator(10)));
the issue is that it's valable just for integer numbers, and i want make it now valable for decimal numbers, so when the user type 254648,32
it converts it to 254.648,32

here is a proposed solution using numberformat :
public class MoneyTextFieldOperator implements UnaryOperator<TextFormatter.Change> {
Pattern p;
int length;
public MoneyTextFieldOperator(int length) {
this.length = length;
this.p = Pattern.compile("[0-9. ,]*");
}
#Override
public TextFormatter.Change apply(TextFormatter.Change c) {
Pattern acceptedKeywords = Pattern.compile("[0-9 . ,]*");
int wholeNumberLength = 9;
int decimalPartLength = 2;
String newText = c.getControlNewText();
String wholeNumber;
String decimalPart;
if (newText.contains(",")) {
wholeNumber = newText.substring(0, newText.indexOf(","));
decimalPart = newText.substring(newText.indexOf(",") + 1, newText.length());
} else {
wholeNumber = newText;
decimalPart = "";
}
Matcher matcher = acceptedKeywords.matcher(newText);
boolean isMatchingWithAcceptedKeywords = matcher.matches();
String letter = c.getText();
if (newText.isEmpty()) {
return c;
} else if (!c.isContentChange()) {
return c;
} else if (countChar(c.getControlNewText(), ',') > 1) {
return null;
} else if (!isMatchingWithAcceptedKeywords) {
return null;
} else if (wholeNumber.replace(".", "").length() > wholeNumberLength || decimalPart.length() > decimalPartLength) {
return null;
} else if (c.getControlNewText().charAt(0)==',') {
return null;
}
else {
c.setRange(0, c.getControlText().length());
if (newText.contains(",")) {
c.setText(NumbersTools.getMonetaryFormat(Integer.parseInt(wholeNumber.replace(".", ""))) + "," + decimalPart);
} else {
c.setText(NumbersTools.getMonetaryFormat(Integer.parseInt(wholeNumber.replace(".", ""))));
}
c.setCaretPosition(c.getText().length());
c.setAnchor(c.getText().length());
return c;
}
}
public int countChar(String string, char charactere) {
int x = 0;
for (int i = 0; i <= string.length() - 1; ++i) {
if (string.charAt(i) == charactere) {
++x;
}
}
return x;
}
and you use it as follow :
textField.setTextFormatter(new TextFormatter<Object>(new MoneyTextFieldOperator(10)));

StringBuilder delete method cannot delete all '0' in for loop

I hava a StringBuilder Object named ans which start with lots of '0'. I try to delete all the '0' from the start of the ans until I meet a non '0' charactar.
What confuse me is the for i loop didn't finish his job. I have to make a second for i loop to clear all the 0 in the beginning.
Here is my Code.
public class No402 {
public static void main(String[] args) {

here is my debug picture
Please help me , thank you!

The reason why all 0's are not deleting after the first loop is that you are removing elements inside the loop if the first character is zero. Which causing the decrease in ans.length() so due to this the loop is not going up to the full length.
One more thing there is no need for 2 for loops you can manage it with just one loop.
How to fix?
Just store the actual length of ans before beginning the deletion and place it in the loop condition like this
public class No402 {

I am a bit new to java and was hoping if anyone could help me. I'm writing this code on virtual machine Ubuntu using the text editor. The RAM errors is right here if you would like to reference the file. http://users.cis.fiu.edu/~crahn/CGS3767/RAMerrors. The error is located in the public static readingLine in the System.out.printf. If anyone could help me idenify the error, I would greatly appreciate it. Thank you!

You want a %s conversion for your String argument recordingLine, not %g

recordingLine is expected to be float but found to be string.

My parser function is not working

I was designing a simple parser(it works on a simple version of Shunting Yard Algorithm). Here's my code(I haven't dealt with associativity).
public class Parser {
String stack[] = new String[50];
String res = "";
int top = 0;
Operator o1 = new Operator("", 0, 0);
public String parse(String x) {
push("(");
x = x + ")";
for (int i = 0; i < x.length(); i++) {
if (o1.isNumber(x.charAt(i) + "")) {
res = res + x.charAt(i);
} else if (x.charAt(i) == '(') {
push("(");
} else if (o1.isOperator("" + x.charAt(i))) {
if (top != -1) {
while ((top != -1) && (o1.isOperator(stack[top]))) {
int m = o1.getOperatorIndex(stack[top]);
int mp = o1.op[m].prec;
int xp = o1.op[o1.getOperatorIndex("" + x.charAt(i))].prec;
if (m >= xp) {
res = res + stack[top];
}
top--;
}
}
push("" + x.charAt(i));
} else {
if (top != -1) {
while ((top != -1) && (stack[top] != ")")) {
if (o1.isOperator(stack[top])) {
res = res + stack[top];
}
top--;
}
}
}
}
return res;
}
public void push(String m) {
if (top != 49) {
stack[top] = m;
top++;
} else {
System.out.println("Overflow");
}
}
}
I guess you won't need the Operator class's code. When I try executing parse("1+2"), it just returns 12 and not the + sign. What is wrong? and yes, o[0] is +,o[1] is -,o[2] is*, o[3] is /

jLabels will not change color

I am developing a Sorting Algorithm Simulator in NetBeans using an applet. I have a Timer and a TimerTask. I want to change the background color of labels according to how they sort. The first run changes the colors but after that the colors don't change. I ran the program in debug mode and saw that after the first run a InterruptedException is thrown from the TimerTask. I have no idea why this is happening.
This is my TimerTask method which has the run() method in it.
Sorry if its lengthy code.
private class AnimationUpdator extends TimerTask {
JLabel[] values = {valuejLabel3, valuejLabel4, valuejLabel5, valuejLabel6, valuejLabel7,
valuejLabel8, valuejLabel9, valuejLabel10, valuejLabel11, valuejLabel12};
JLabel[] pointer = {pointerjLabel3, pointerjLabel4, pointerjLabel5, pointerjLabel6, pointerjLabel7,
pointerjLabel8, pointerjLabel9, pointerjLabel10, pointerjLabel11, pointerjLabel12};
JLabel[] okPointer = {okjLabel3, okjLabel4, okjLabel5, okjLabel6, okjLabel7,
okjLabel8, okjLabel9, okjLabel10, okjLabel11};
int runCount = 0;
public void run() {
if (order.equals("Ascending")) {
if (i == 10) {
pointer[i - 1].setVisible(false);
jLabel3.setText("Sorted!!!");
stop();
} else {
JLabel key = values[i];
key.setBackground(Color.red);
j = i - 1;
int init = 0;
pointer[i].setText("i-->");
pointer[j].setText("j-->");
pointer[i].setVisible(true);
pointer[j].setVisible(true);
while (j >= 0 && Integer.parseInt(values[j].getText()) > Integer.parseInt(key.getText())) {
values[j].setBackground(Color.blue);
insert.setLabel1x(values[j].getX());
insert.setLabel1y(values[j].getY());
if (swap) {
insert.setLabel2x(values[i].getX());
insert.setLabel2y(values[i].getY());
