DOM Parsing Method
Feb 26, 2015
I've been staring at my code for the past few days and I just can't get it to work out. I'm trying to parse a DOM object with the following XML loaded:
<?xml version='1.0' encoding='UTF-8' ?>
<form>
<record event="boot" date="2013-11-01">
<text>system boot</text>
</record>
<record event="login" host="localhost" date="2013-11-01">
[code].....
I'm trying to get all of the attributes that I care about out of the <record> tags (date, event, etc ...) and stick the data in a wrapper class (DocumentData). If you run this, you'll see that it is close to working, but I'm having trouble getting the attributes in the <subject> and <return> tags (I need to get the errval and uid attributes).

I'm simulating temp/humidity values and want to separate the string value reported and parse each part (left and right) for their respective values. However, I'm having trouble figuring out how to parse the right hand side of this string value, I can get the left using split (shown below), but I think split removes the right hand side of the string value.
the value reads "Temp=22.9*C Humidity=50.9%"
Java Code: private Double parseTemperatureFromString(String consoleOutput) {
String[] tempHumidParts=consoleOutput.split(" ");
String[] tempPart=tempHumidParts[0].split("=");
String theTemp=tempPart[1];
theTemp=theTemp.replace("*C","");
return Double.parseDouble(theTemp);

System.out.println("Demonstrating block scope");
int x = 1111;
System.out.println("In first block x is " + x);

this is the error I'm getting..reached end of file while parsing. I think this is referred to as either an extra curly brace or that I am missing a curly brace but I'm not 100% sure.

I have to read this CSV file into an arraylist. Arraylist i call weight. The data in the csv file has 200 double values which is the weight of all the 200 bananas. Since the csv file is a string i guess I cannot create an double arraylist from scratch, but i have to parse the csv file afterwards, right? Well this does not work and ill show you the code in a bit, just need to state all my issues.
My second issue is how to be able to print out the the weight items (in this case bananas) next to the weight of the bananas taken from the array? This has to be done by constructor i assume? I just dont know how constructors work with arraylists.
Id like it to look something like this in the output window.
Banana 34,55
Banana 43,55
Banana 23,74
and so on (200 times)
so these are my issues, how to parse and how to print the arraylist weights and the item banana in the output window with constructor. Here is the code.
package Main;
import java.io.BufferedReader;
import java.io.FileReader;
import java.util.ArrayList;
import java.io.IOException;
import java.io.Serializable;
import javax.swing.JOptionPane;

I'm having some kind of weird problem reading input from a file. It says that my scanner object I'm using to hold an item of information isn't initialized, when I do try to initialize it, it says error variable already initialized. I'm using the scanner to read input from a file whose contents are this

150.4
88.4
-3.14
499.4
799.4
1299.8

import java.util.*;
import java.io.*;

This is the error message

I have to write Scanner and Parser for the C-Code based on Java and obtain Abstract syntax tree(AST) . I am allowed to use tools like ANTLR, CUP. But i should be able to expand all macros in my code to its basic low level data type like int, boolean and whats the best approach?How to start initially?

I am trying to merge two files together using the Apache Commons CSV library. I figured it was easier to use this than to write my own implementation.
The first problem is that the output contains the underlying class logic and as a results my output contains a bunch of un-needed data. How do I get rid of this? I just want the column and row data, nothing else.
Example
I want this:
customerNo, firstName, lastName, birthDate, mailingAddress, married, numberOfKids, favouriteQuote, email, loyaltyPoints
1, John, Dunbar, 13/06/1945, 1600 Amphitheatre Parkway Mountain View, CA 94043
But I get this:
CSVRecord [comment=null, mapping=null, recordNumber=1, values=[customerNo, firstName, lastName, birthDate, mailingAddress, married, numberOfKids, favouriteQuote, email, loyaltyPoints]]
CSVRecord [comment=null, mapping=null, recordNumber=2, values=[1, John, Dunbar, 13/06/1945, 1600 Amphitheatre Parkway
Mountain View, CA 94043
The second problem is that I just want the row Headers from the first file, but the row headers from my second file are still being included in my output. I used withSkipHeaderRecord(true), but it didn't have the desired results.
Code is below.
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.Reader;
import java.util.ArrayList;

I'm working on a small game, and I have a quick question about parsing a file. Basically, I have a utility method, which loads an XML file containing the details of all the items for the level, and then pulls the info and passes it to the Item constructor.
A snippet of the XML file is:
<item key = "Weapon1" name = "Sword" description = "A basic sword... etc" hint = "picked up SWORD" givesPlayer = "basicSword:1" bitmap = "5,5" />
And a snippet of the class is:
public class Item extends Entity {
String name;
private String description;
private String hint;
private Map<String, Integer> givesPlayer = new HashMap<>();
private boolean pickedUp;
[Code] ....
The XML file contains this field:
bitmap = "5,5"
which basically specifies a column and row where it should grab an image from, located elsewhere.
My question is this: Should I parse this "5,5" in my utility method and pass the image(s) to the constructor(// B Consturctor), or is it ok to pass the location as a String and parse it in the Constructor( // A Constructor) ?

I thought of processing line by line using scanner and then split each line in the ":" . But then i stuck, i only need the right part of the ":" so that i can save it to a class e.g. John Doe, 133456593, married etc.
Java Code: Name: John Doe
TRN: 133456593
Status: Married
Income: 22500
Receipts:
Receipt ID: 1

In the code below I am splitting the String relativeDN at the "," character. After splitting the String I need to parse the string from the "=" character using indexof and then rebuild the string. I was able to parse the first = sign then rebuild the string but it doesn't remove the subsequent = character. I am trying to parse the string using idexof for all the "=" characters and then rebuild it using StringBuilder.
public class StringTestProgram {
public static void main(String[] args) {
String relativeDN = "cn=abc,dn=xyz,ou=abc/def";
//Split String
String[] stringData = relativeDN.split(",");

What the program must do is to parse the string-declared two-dimensional array for the program to compute the student's scores in their quizzes, but I'm having difficulty in anything with Parsing so I don't know what will be the appropriate codes.
Error: incompatible types: String[][] cannot be converted to int[][]
import java.io.*;
public class Quiz3{
public static void main(String[]args)throws IOException{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String [][]StudQuiz = new String [5][4];
[Code] ....
How am I able to compute the average of the score if the data that is needed to be computed is in the string-declared array?

I am new to java coding. so, reading the log file using java code.
1) I wish to parse a file, and find a value for variable e.g. [StorageVersion].
2) After finding the value, it will be pushed to database.
Following is the code that i have written till now.
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.io.*;
import java.lang.*;
import java.util.*;
import java.util.regex.*;
[code]....
1) I don't know what regular expression can i use.
2) I want a line to check that preceding line should have //StorageVersion .
3) n then i will check any string between := K[' and '];. From above log file "'706146.0.22106932'" is the value that i am looking for.

I have started learning Java and have some across some difficulties. I'm trying to subtract two strings.
for example, with these strings;"032"&&"100". I want to be able to subtract each number individually so that the answer would be "032". 0-1;3-0;2-0;. if i get a negative number, the number would be zero. hence, the 0-1 staying zero in the answer.
I have tried using substring, and parsing the two values to ints, but don't know what to do next. I have also tries using a for loop, to go through each arrays of the strings. I am not allowed to use StringBuilder and I need to return "032".
Here's what i've done so far:
public static String appliquerCoup( String combination, String coup ) {
String nouveauCoup="";
if(combination!=null&&coup!=null){
for(int i=0;i>combinaison.length();i++){
