You can create classes without a pointer but they will just be collected by the garbage collection machine unless you’re passing them to something that uses the new object you’re creating. This is nothing in Java: myObject … Read more
I shouldn’t, but check this out: Matcher m = Pattern.compile(test.replace(“{“, “\\{(“).replace(“}”, “)\\}”)).matcher(test); m.find(); for (int i = 1; i <= m.groupCount(); i++) { System.out.println(m.group(i)); } Ideone Demo 1 solved Reading data within parenthesis

As per the HTML you have shared you can use either of the following solutions: linkText: @FindBy(linkText = “My transfer”) WebElement transferBtn; partialLinkText: @FindBy(partialLinkText = “transfer”) WebElement transferBtn; xpath: @FindBy(xpath = “//a[contains(.,’My transfer’)]”) WebElement transferBtn; solved Selenium @FindBy linkText or @FindBy partialLinkText not working
I’ll document all my solutions to this problem. This is the 1st resolution. The clue was here. I upgraded Open JPA from 2.2.0 to 2.2.2 & the exception went away, so it appears that it was a bug. This happened again. I was missing cglib.2.2.3.zip and/or cglib-nodep-2.2.3.jar. solved org.apache.openjpa.persistence.PersistenceException: null

Your code will be quite similar to the code you already have. Edit: I mean the code in the question; only after writing the answer I became aware that someone else had … Read more

Java Code String s;// Your string String r;// Your regexp Pattern p = Pattern.compile(String.format(“.+?(%s).*”,r)); Matcher m = p.matcher(s); if (m.find()) { System.out.println(m.group(1)); } Note I assume your regexp will be matched only one time in your string s. 1 solved How do you … Read more
In your code, int l= arr[0].length; in this line, arr[0] represents the value in array named as arr at 0th index. Hence length function can be used in this way to find the length of value stored in array at 0th index. int l = arr[0].length(); In order to find out the length of array, … Read more
It depends on what kind of project you are doing. I wouldn’t recommend to have the question in the code, as it can get complicated and messy with if there is a large amount of questions. File work good, but wouldn’t recommend doc format, a plain “.txt” format is easier to code with. Database also … Read more
I couldn’t quite work out your logic but I think you may benefit from using a key here to look up the SecDef element using its MktSegGrp attribute value <xsl:key name=”MktSeg” match=”SecDef” use=”MktSegGrp/@MktSegID” /> So, for a given MktDef, you would get the SecDef elements for it like so <xsl:variable name=”secDef” select=”key(‘MktSeg’, @MktSegID)” /> Try … Read more
