Data Getting Overridden On Loop After Parsing A Xml
Mar 14, 2015
I have an xml with 'n' number of data which i am parsing,for test i hardcoded without looping has below,now the below line is just parsing and showing the data for index '1' ,i need to loop this and i am not sure how can i do this.How do i find the length of obj and loop,i cannot find any method in SoapObject.I used like below but the data is getting overridden after parsing
for(int i=0;i<obj.getPropertyCount();i++) {
KSoap2ResultParser.parseBusinessObject(obj.getProp erty(i).toString(), getReminder);
}
call in another class
public static void parseBusinessObject(String input, Object output) throws NumberFormatException, IllegalArgumentException, IllegalAccessException, InstantiationException{
I am suppose to display some information from some text files I tried to do that but the output gives me information from one text file and not information from all text files.
public static void main(String args[]) throws IOException { String occupations; double unemployRate_By_Occupations_2008; double unemployRate_By_Occupations_2009; double unemployRate_By_Occupations_2010; //declare the file object and open the file "occupations.txt"; File myFile = new File("occupations.txt");
[code]....
The first text file is:
2.5 3.3 2.6 3.1 2.4 2.7 2.6
[code]....
the second text file is:
4.6 5.7 5.2 6.9 4.5 4.3
[code]....
The third text file is :
4.8 5.6 5.2 6.2 4.6 4.6 2.7
[code]....

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.
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.
I am trying to use double data type in a for loop for precise operations and just to see if there could be any problem doing that I tested a small code :
public class doubleLimit { public static void main(String[] args){ for(double i=-0.1;i<=0;i+=0.01) System.out.println(i); }}
The output I was expecting is : -0.1 -0.09 -0.08 -0.07 -0.06 -0.05 -0.04 -0.03 -0.02 -0.01 0.00
But the output of the code is : -0.1 -0.09000000000000001 -0.08000000000000002 -0.07000000000000002 -0.06000000000000002 -0.05000000000000002 -0.040000000000000015 -0.030000000000000013 -0.02000000000000001 -0.01000000000000001 -1.0408340855860843E-17
Why is the code not working the way I expected, I think it has something to do with any property of double but I am not sure.
import java.lang.*; class InvalidValueException extends IllegalArgumentException {} class InvalidKeyException extends IllegalArgumentException {} class BaseClass { void foo() throws IllegalArgumentException { throw new IllegalArgumentException();
[Code] .....
Which one of the following options correctly describes the behavior of this program? And the answer is (definitely) --> The program will print : InvalidKeyException exception, but when i saw the explanation, it tells
It is not necessary to provide an Exception thrown by a method when the method is overriding a method defined with an exception (using the throws clause).
I don't know, but i think it will compiled because the Exception that is thrown by the foo method in DeriDeri class is inherited from unchecked exception.. so it is not necessary to declare throws statement on its method.. and if the exception was checked exception the answer must be different right?
Java Code: class A { int x=5; } class B extends A { int x=6; } public class CovariantTest { public A getObject() {
[Code] ....
And this is the output I get:
sub 5
I am unable to figure out how this is outputting 5 instead of 6. The getObject method of SubCovariantTest is obviously the one being called, and it returns a new B(). So why am I getting class A's x value? I thought since I was getting a B object returned that I would get B's x value.
why overridden doesn't apply to variables. However, instance variables are stored inside the object.I ran below program and expected to print "two" but it gets printed "one".
class SupCont { String s = "one"; } class Cont extends SupCont { public static void main(String a[]) { String s = "two"; SupCont c = new Cont(); System.out.println(c.s); } }
If a method is overridden but you use a polymorphic (supertype) reference to refer to the subtype object with the overriding method, the compiler assumes you're calling the supertype version of the method.
is this true? maybe i'm misunderstanding it, but i thought the JVM looks at the object at run time and checks the object type. the context of the quote is about checked exceptions, but it seems like the statement should stand regardless of context. but this doesn't back up my experience. for example:
public class Test{ public void print(){ System.out.println("Super"); } public static void main(String[] args){ Test t = new SubTest();
[Code] ....
Will invoke the subclass method. like i said, maybe i'm missing something.
I don't understand, why when in the constructor of the superclass A the method init() is called (line 4), the overridden version of the subclass is invoked (line 26) and not the superclass version (line 7):
class A { public A () { init(); } public void init() { System.out.println("test");
[Code] ....
I would have guessed that above code prints
test 1
But instead you get a NPE (because when the constructor of B is invoked
public static void main(String[] args) { new B(); }
Then there is first the implicit call to super:
public B() { s = " "; init(); }
Which is the constructor of A:
public A () { init(); }
But here now this init() method is not the version of A ( public void init() { System.out.println("test"); }) but the overriden version of the subclass (B): public void init() { System.out.println(s+=s.length()); }...
Which throws an NPE of course, because the initialization of s has not occured yet (it happens only after the implicit call to super() has finished (see public B() { s = " "; init(); }))
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:
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.

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.
I have a String formated in the same way as package names:"com.darkchanter.code.NameValue"..Now I need to extract "NameValue" - the problem doesn't actually block my stuff, but before I write my own code, I Wonder if there is a function already available...
I m trying to migrate JSF 1.2 project with myfaces to JSF 2.0 with myfaces 2.0 jars on weblogic10.3 server. Found some problem related build and publishing after resolving them when i hitting my application all JSF html tags are coming in browser as it is they are parsed to html tags. all h: tages are coming as it is on my browser they are not converted to html tags for browser display.
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
import java.util.*; import java.io.*; public class QudratullahMommandi_3_07 { Toolkit_General toolKit = new Toolkit_General(); public static void main (String[]args)throws IOException
[Code] .....
This is the error message
QudratullahMommandi_3_07.java:34: error: variable holder2 might not have been initialized String holder2 = holder2.trim(); ^ 1 error

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?
