Start by learning the basics by reading books, doing tutorials, watching videos, etc. Then, I would suggest making some application. I learn best by doing so I'd make some sort of app.

Hello everyone
I'm trying to pass the matchday to the URL for the Http connection. I know I can't get a value from the EditText in the doInBackground method so I thought to get the value in the onPreExecute method. Of I then add the variable to the URL, the program doesn't recognise the String. I saw on StackOverflow you need to add the parameters in the execute method but I don't really have got that part of the explanation. 
Does anyone have an idea how to add the matchday to the URL, entered in the EditText matchdayText?
Thanks in advance!

I have two different XML documents below and please note that they are having the same basic structure (schema).
Source XML
<root>
<name>String</name>
<description>String</description>
</root>
Test XML
<root>
<name>Test</name>
<description></description>
</root>
And I build this snippet function to compare those two XML documents.
import org.custommonkey.xmlunit.Diff;
import org.custommonkey.xmlunit.Difference;
import org.custommonkey.xmlunit.IgnoreTextAndAttributeVal uesDifferenceListener;
import org.custommonkey.xmlunit.XMLUnit;
public static void main(String args[]) throws FileNotFoundException,
SAXException, IOException, ParserConfigurationException, XPathExpressionException {
String strSource = "<root><name>String</name><description>String</description></root>";
String strTest = "<root><name>Test</name><description></description></root>";
Document docSource = stringToXMLDocument(strSource);
Document docTest = stringToXMLDocument(strTest);
boolean result = isMatched(docSource, docTest);
if(result){
System.out.println("Matched!");
}else{
System.out.println("Un-matched!");
}
}
public static boolean isMatched(Document xmlSource, Document xmlCompareWith) {
XMLUnit.setIgnoreWhitespace(true);
XMLUnit.setIgnoreComments(true);
XMLUnit.setIgnoreAttributeOrder(true);
XMLUnit.setNormalizeWhitespace(true);
XMLUnit.setIgnoreDiffBetweenTextAndCDATA(true);
Diff myDiff = new Diff(xmlSource, xmlCompareWith);
myDiff.overrideDifferenceListener(new IgnoreTextAndAttributeValuesDifferenceListener());
return myDiff.similar();
}
public static Document stringToXMLDocument(String str) throws ParserConfigurationException, SAXException, IOException{
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
docBuilderFactory.setNamespaceAware(true);
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document document = docBuilder.parse(new InputSource(new StringReader(str)));
return document;
}
And here is the Maven dependency
<dependency>
<groupId>xmlunit</groupId>
<artifactId>xmlunit</artifactId>
<version>1.6</version>
</dependency>
I am expecting those two XML documents are the same, but the function always returns false. Are there any ways that I can ignore the node text value when comparing two XML structures? As you can see, I already used IgnoreTextAndAttributeValuesDifferenceListener, but I still got the problem.

You are more likely to get help from the owners of the XMLUnit package.

That code really does not make much sense. I suggest you go to The Java™ Tutorials[^], and work through them.

Im self studying and purchased the ap book. I don't understand the following question:
consider a b c are integers consider this boolean expression
(a < b ) || !(( c==a * b)) && (c < a )
the answer is
c < a is false
would someone please explain HOW thats the answer? tysm

It's not the answer. The answer will depend on the values of a, b and c.

If you have String array arr = {"145", "457", "784", "258"}, is there any other quicker way to convert each element of the array to Integer without using any loop? The below approach can work, but it will require each element to be explicitly converted to Integer.
myIntArray = new int[arr.length];
For(for int i=0; i

What is wrong for you with using the loop?

No.

Well that is true whether you use a loop or not.

The fact that your byte array would perfectly fit into a __m128i makes me wonder if that is a homework question. I am not a Java programmer so I have no idea if it is even possible in Java. However with C you could parse it in-place with SSSE3:
#include <emmintrin.h>
#include <intrin.h>
CHAR source_array[4][4] = { "145", "457", "784", "258" };
INT target_array[4] = { 0, 0, 0, 0 };
__m128i target = _mm_loadu_si128(reinterpret_cast<__m128i *>(source_array));
__m128i subtract_me = _mm_set1_epi8('0');
__m128i numbers_array = _mm_subs_epu8(target, subtract_me);
__m128i mul_deci = _mm_setr_epi8(10, 1, 10, 1, 10, 1, 10, 1, 10, 1, 10, 1, 10, 1, 10, 1);
__m128i deci = _mm_maddubs_epi16(numbers_array, mul_deci);
__m128i mul_centi = _mm_setr_epi16(100, 1, 100, 1, 100, 1, 100, 1);
__m128i centi = _mm_madd_epi16(deci, mul_centi);
target_array[0] = centi.m128i_i16[0]/10;
target_array[1] = centi.m128i_i16[2]/10;
target_array[2] = centi.m128i_i16[4]/10;
target_array[3] = centi.m128i_i16[6]/10;
Maybe a Java programmer can let us know if SIMD intrinsics can be translated into Java.
Best Wishes,

Can anyone help me figure this out? I wrote the following code for my programming class.
package weekthreeassignments;
public class Odds {
public static void main(String[] args) {
int product = 1;
for (int i = 1; i <= 15; i++)
if (i % 2 == 1) {
product *= i;
}
System.out.println("Product of the odd integers from 1 to 15 is: " + product);
}
}
When I run the code I get the following error and how to fix it, but if you read the "Please define" part, I did define it that way. Why am I still erroring?
Error: Main method not found in class weekthreeassignments.Odds, please define the main method as:
public static void main(String[] args)
or a JavaFX application class must extend javafx.application.Application
C:\Users\fred\AppData\Local\NetBeans\Cache\10.0\ex ecutor-snippets\run.xml:111: The following error occurred while executing this line:
