I know adjacent delimiters create empty token but is there any exception regarding last pair of delimiters ??
String a[]=":ab::cde :fg::".split(":"); // Creates 5 tokens
String a[]=":ab::cde :fg:: -Space-".split(":"); // Creates 7 tokens
I have a String as follows: "the|boy|is|good"
now, I want to split this string using the "|" delimeter.
I tried this :
String line = "the|boy|is|good";
line.split("|");
But it didn't split it. Is there some regex for "|"?
I am having a problem with the following code. It compiles and runs fine however my output is wrong.
public class SplitString {
public static void main(String[] args) {
String[] string1 = split("ab#12#453", "#");
String[] string2 = split("a?b?gf#e", "[?#]");
for (int i = 0; i < string1.length; i++) {
System.out.print(string1[i] + ",");

The split method in the String class returns an array of strings consisting of the substrings split by the delimiters. However, the delimiters are not returned. Implement the following new method that returns an array of strings consisting of the substrings split by the matching delimiters, including the matching delimiters.public static String[] split(String s, String regex)For example, split("ab#12#453", "#") returns ab, #, 12, #, 453 in an array of String, and split("a?b?gf#e", "[?#]") returns a, b, ?, b, gf, #, and e in an array of String.
I am currently trying to make a calculator in Java. I want to use the String split method to tokenize the string of characters inputted. I thought I was using the String split method wrongly, because I had surrounded the characters I wanted to delimit with square brackets. However, when I removed the square brackets, the code threw an exception when I pressed the equal button. The exception was a PatternSyntaxException exception. Am I using the String split method wrongly? And why is the exception thrown? Here is my code:
import javax.swing.*;//import the packages needed for gui
import java.awt.*;
import java.awt.event.*;
import java.util.Arrays;
import java.util.List;
import static java.lang.Math.*;

I am trying to split a string based on length(example length 5) of the string. But I am having a issues with this substring(start, end) method. I get all substring which are of length 5. But if the last substring is less than 5 then I am not getting that last substring. But I need the last substring even if it is less than 5.
String s = "fjdjfdfjgffgjhfjghfjkhjhjh";
String spLine;
for(int i=0; i<s.length(); i=i+5){
spLine = s.substring(i, (5+i));

So I'm creating a class which when given three inputs uses them as sides of a triangle and tells ther user what type of triangle it is, or if the input is invalid, tells them why it is invalid. I'm readin the input as a string and then trying to split it into a string array, from there checking to see if it has 3 elements.. in which the data is good at that point, and then converting them to ints and checking to see if they're negative ansd finally checking to see if they can work as sides of a triangle ie a+b >c, a+c >b , b+c >a.
I'm trying to split it into an array of strings but am getting an error, and can't seem to figure out why as this should be working from what I've read of the string.split method online.
import java.util.*;
public class TriangleTest{
private int sideA;
private int sideB;
private int sideC;
public static void main(String[] args){
TriangleTest triangle = new TriangleTest("3 4 5");
[Code] ....
The output reads [Ljava.lang.String;@15db9742
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
I have a string that look like this
"dfhsdfhds | dsfdsfdsfd dsfjkhdskjf ||ER|| jdkshfuiewryuiwfhdsfsd er dsfjsgrwhfjkds ||ER|| jkshruiewryhijdknfjksdfhdksg | "
I want to split it by "||ER||"
I try this but it splits the single "|" to not just the "||ER||" like I want.
String[] separated = response.split("||ER||");
Log.d("token",separated[0]);
Log.d("token",separated[1]);
String path = "/AUTOSAR/Os_0?type=EcucModuleConfigurationValues";

In this exercise, create a program that asks a user for a phrase, then returns the phrase with the words in reverse order. Use the String class's .split() method for this.
Example input
The rain in Spain falls mainly on the plain
Example output
plain the on mainly falls Spain in rain The
While I understand the assignment, nowhere in the text is it covered how to reverse the order of the words in the string. I understand using the .split method, but not for this exercise.
Here is my code so far.
import java.util.*;
/**
* Java class SplitString
* This program asks for a phrase, and the code allows the phase to return in reverse order.
*/
public class SplitString {
public static void main (String[] args){
//set phrase input and mixed which will be the result
[Code] ....
As you can see, I have been googling this method and have come up nearly empty. My text does not cover the .reverse() method. The only thing it covers with .split() is how to split a string. I also tried StringBuilder with no success.
I am trying to get resultset into a string and then use split method to store it in an array but it is not working. i tried to work it seperately as java program but it throws exception "could not find or load main class java."
String ar = "This.is.a.split.method";
String[] temp = ar.split(".");
for(int i=0;i<temp.length;i++){
System.out.println(temp[i]);
}
I am encountering a problem while running this small piece of code.
public class TestSplit{
public static void main(String[] args){
String myWords[]="My.Home.Is.Being.Painted".split(".");
for(int i=0;i<myWords.length;i++)
System.out.println(myWords[i]+" ");
}
}
The problem is: it does not run at all. No error message is displayed. It just returns to the command prompt when i run it. Where am i wrong?
String str = "#11* 1# 2*12# 3"

Regular expression which I want to use to split a string. The string could look similar to this:
"a = "Hello World" b = "Some other String" c = "test""
The String is read from a file where the file contents would be:
a = "Hello World" b = "Some other String" c = "test"
After splitting I would like to get the following array:
String[] splitString = new String[] {"a", "=", ""Hello World"", "b", "=", ""Some other String"", "c", "=", ""test""}
I know I could just write a simple text parser to go over the string character by character, but I would rather not do it to keep my code clean and simple. No need to reinvent the wheel.
However, I just cant seem to be able to find the right regular expression for this task. I know that a RE must exist because this can be solved by a finite automaton.
I am trying to split the contents of the text file and assign the value on the left of the separator to a variable and the value on the right of the | separator to another variable. Thus I tried out a sample code to print all the values in the split [] first, and ended up with problems. This is the content of the text file:
Crazed Boy|20
Hello|5
MSB|6.5
public class Main {
public static void main(String[] args) {
try {
BufferedReader infile = new BufferedReader(new FileReader("test1.txt"));
for (int i =0; i < 3 ;i++) {
String s = infile.readLine();
String[] ss = s.split("|");
[code]....
I keep getting IOException in my sample code, why is this so ? I assumed the split() method is supposed to output for the 1st iteration:
ss[0] = Crazed Boy
ss[1] = 20
I have included split() to put a string read from a given file into indexed array. Looking for a word position (not char position number in addition to the line number I have already written. Line number works fine, however word position isn't quite right.Below is my code:
import java.io.*;
public class Word implements Comparable, TreeComparable{
String word;
int count;
int wordpos;
ObjectList lines;
private SuperOutput so;

I used the string split method in the following lines of code like this:
String[] numbers = out.split("[^d.]", 0);
String[] operations = out.split("[.d()]", 0);
When out is equal to the String "2x2.5", the array operations ends up looking like this when it is printed using the toString method:
[, , , x]
As you can see, before the array element x, there are three String variables which only contain whitespace. Why does this occur, and how can I prevent this from happening?
Need code logic or regex to get substring between two different delimiters and then parse it into Integer array.
My Input String is : Transmitter#MSE14_REC_FTP40 #138^TPPurgeUility_test #103^YUG_Trans #57^
Output (ie. substring between "#" and "^")
138

I have saved emails that are stored in to text files and I want to retrieve the Sender, Reciever, Subject and the Email Content.I am using From: as a delimiter and To: as a delimiter and Subject as a delimiter and I am not sure what delimiter I should set for the email content.Also, there can be emails that will have comments after the message content and I plan on using the delimiter Comments:.
Any example of what delimiters I should use it would be great. Also I would like to know how check whether or not a delimiter exists so that I can print out the comments if it exists and if the file does not have comments, it prints out nothing.

String math = "23+4=27"
int num1 = (23 STORES HERE)
int num2 = (4 STORES HERE)
String operator = (+ STORES HERE)
int answer = (27 STORES HERE)
Note that the operator can be either + - * /
How to split an XML file in java? what function and package should we use?
View Replies View RelatedMy problem is with ItemListener I'm not sure why it is not working. Well I'm trying to split the ItemListener into two class. In the main class I have this :
final JCheckBox whole_C_CheckBox = new JCheckBox("Whole");
whole_C_CheckBox.addItemListener(new CheckBox(whole_C_QTextField, whole_C_WTextField, whole_C_PTextField));
whole_C_CheckBox.setVerticalAlignment(SwingConstants.BOTTOM);
whole_C_CheckBox.setHorizontalAlignment(SwingConstants.LEFT);
whole_C_CheckBox.setBounds(12, 66, 113, 25);
chikenPanel.add(whole_C_CheckBox);
In the other class I have
public class CheckBox implements ItemListener{
private JTextField q;
private JTextField p;
private JTextField w;
private JCheckBox whole_C_CheckBox;
public CheckBox(JTextField whole_C_QTextField, JTextField whole_C_WTextField, JTextField whole_C_PTextField) {
[Code] ....
will when I try to run the program its working.However, when I click on the Check Box for (whole_C_CheckBox ) it give an error I don't know what is wrong with my code.
Note: in the main class all these whole_C_QTextField, whole_C_WTextField, whole_C_PTextField has been set in default to (0, 0.00, 0.00), so I'm trying when I click on Check Box for (whole_C_CheckBox ) it will set them to nothing, and if I unchecked them again they will return to their default (0, 0.00, 0.00).
how to split and then represent the splitted sentence.Suppose I have:
Java Code:
String sentence = "I Love my mother <=> I Love my father";
String[] array = sentence.split("->"); mh_sh_highlight_all('java');
But how can I get now the lefthandside String values which is "I love my mother" and righthandside "I love my father"? I tried smth like:
Java Code:
String[] leftHandSide = array[0].split(" ");
String[] rightHandSide = array[1].split(" "); mh_sh_highlight_all('java');
But it's not working - getting error.
I've found different examples on line, but none that use the split method with a multidimensional array. I would like a user to input coordinates (x,y) for city locations and store them into a 2-D array. For the user to input the x,y-coordinates on one line I need to use split(',') and then parse the string array to a double which will then be used to calculate the distances from one another.
My issue is how to store the String vales into the 2-D array. I do not want to store the x-value at even (cityArray[0]) and y-value at odd (cityArray[1]) 1-D locations.
