Split String From Given File Find Word Position
May 4, 2014
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;
[code]....

So I need to print out the table of conversions from kilogram to pound and from pounds to kilograms. I think I have done a while loop correctly, but it is hard to actually check it since I do not have proper output format. I have tried also %4.2f format option however could not find the proper position in the print.
public static void main (String[] args){
System.out.printf("%10s%10s | %10s%10s
", "Kilograms", "Pounds",
"Kilograms", "Pounds");
System.out.println("---------------------------------------------");

I have built a binary tree, from a file. In each node, I am storing each word as a string, and an int frequency for each time the word occurs. For the assignment, I need to find how many words occur only once in the file. I wrote the program, but for some reason I am getting a number different from what my professor is expecting.
As far as I know, this file has loaded into the tree correctly, because all of my other answers in the assignment are correct. What am I doing wrong?
public void findUnique() {
System.out.println("There are " + findUniqueWords(root, 0) + " unique words.");
}
private int findUniqueWords(Node subTree, int uniqueCount) {
// Base Case: At the end of the branch
if(subTree == null){
return uniqueCount;

I have written the code to read the line from file and save first string as word and and remaining string as meaning..
E.g.: innovation a new method, idea, product, etc.
word = innovation
meaning = a new method, idea, product, etc.
In my code there is no error and have a mistake what it is means first assigning word is ok and while saving meaning ..it saves like
{
a a new a new method } like that
Java Code:
import java.io.BufferedReader;
import java.io.FileReader;
public class Dil{
public static void main(String[] arg)throws Exception
{
BufferedReader in;

The intentions of this program is to prompt a user to enter a file name, and then reads the file. The program will prompt the user to enter a word that needs to be corrected. So lets say I have a text file containing "My name is OP and I Like goind to the Park!" I want to change "goind" to "going",
Now, my second method "isSimilar" executes a similar word with more than one same letter and same length, but I dont know how to execute that whole thing in my third method "correctThisLine" . How I can call that isSimilar method and read in that text file and change that word into that?
import java.util.*;
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class WahidMuhammadA3Q2{
String fileName = "AutoCorrectMe.txt";
public static void main (String [] args){

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.*;
public class CalculatorCopy {
public static void main(String[] args) {

I have to recursively find a given string in a file. I HAVE to use the LineNumberReader class, and the output would be like so:
Line#Found : the string of the whole line
This is the code I've written:
public String findGivenString(String givenString, int currentLineNumber) {
LineNumberReader lnr = null;
try {
lnr = new LineNumberReader(new FileReader(getFile()), 4096);
lnr.setLineNumber(currentLineNumber);
String s = lnr.readLine().toLowerCase();
[Code] ....
I messed around with a bit, and it doesn't change to the new set line. Though the line number is incrementing! So it just keeps checking the first line of the file over and over again, which is why it can't find the given string. Which also throws the StackOverFlow exception I'm getting.
Here's the output if I remove the comment from the System.out...:
String @ that Line# 1: package banking;
String @ that Line# 2: package banking;
String @ that Line# 3: package banking;
String @ that Line# 4: package banking;
....
So you see it keeps checking the same line even though the line number IS incrementing.

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 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

"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]);

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 "|"?

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++){

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?

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 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?
