[ad_1] Consider this line, Test1 t2 = t1.print();//wrong code You have to explicitly typecast in this situation. Test1 t2 = (Test1)t1.print();//correct code You have to explicitly typecast in case of narrowing conversion(Parent class—>child class) Your compiler automatically typecasts in widening conversions(Child class—>Parent class). 3 [ad_2] solved Here is a simple java code giving an error … Read more
[ad_1] There is no way you can hide the HTML source since the code is what the browser get as instructions from the server. But you can minify and uglify your JS/HTML in such a way that they would look convoluted to human eyes. This effectively hides any meaningful variable and function names and would … Read more
[ad_1] To plot two plots (or more) in one figure, you can use the facet_grid function in ggplot2 (http://docs.ggplot2.org/current/facet_grid.html for more info). You can choose on which trait the plots will be facetted by using a formula. On the left hand side you can mention rows (graphs under each other) and on the left hand … Read more
[ad_1] First of all your html structure is invalid, the starting and ending of tags are not proper: <a> tag and <figure> tag are not closing properly, so have a look into it and correct html first I am posting answer by changing some html: $(‘.addBasket’).click(function(){ // here we have used .siblings as we need … Read more
[ad_1] You can’t print the two values by using x[i]. You must print them one-by-one. You probably want something like: for (i=0;i<12;i++) { printf(“\t index %d value %f, %f \n\r”,i, x[i].a, x[i].b); } 1 [ad_2] solved Printing Array in struct
[ad_1] b = max(a) [1 if x==b else 0 for x in a] max(a) will return the maximum element in your list so you want to essentially replace all non-max values with 0 and all max values to 1. You can do this several ways but the above seems most to the point. Basically this … Read more
[ad_1] If all your compound terms are separated only by blanks, you can use gsub: > x = c(“hello World”, “good Morning”, “good Night”) > y = gsub(pattern = ” “, replacement = “”, x = x) > print(y) [1] “helloWorld” “goodMorning” “goodNight” You can always add more patterns to pattern argument.

[ad_1] If your first two arrays has the same length, you can use a loop to get the array you want: <?PHP $arr1= array(“A”,”B”,”C”); $arr2= array(“1″,”2″,”3″); $arr3=[]; for($i = 0; $i < count($arr1); $i++) array_push($arr3, $arr1[$i], $arr2[$i]); ?> It will return: $arr3= array(“A”,”1″,”B”,”2″,”C”,”3″); 1 [ad_2] solved Combine PHP array as something [duplicate]
[ad_1] The str.find finds the index of the item. You need to use str.count. def ex4(str4): someLetter = str4[ :1] return str4.count(someLetter) print ex4(“mldtmgm”) [ad_2] solved python program doesn’t work
[ad_1] As Royal Bg mentions in the comments, if they have the source code, there’s no way you can secure it against them making a separate copy. As you mention, any attempt at a licence key, or any other type of method, they’d be able to get around. [ad_2] solved How can I secure my … Read more
[ad_1] So basically you to first split by – and then each side by a non-word character. Therefore you can try: String s = “ABC_DEF-HIJ (KL MNOP_QRS)”; String[] splits = s.split(“-“); // {“ABC_DEF”, “HIJ (KL MNOP_QRS)”} String[] lefts = split[0].split(“[^a-zA-Z]”); // {“ABC”, “DEF”} String[] rights = split[1].split(“[^a-zA-Z]”); // {“HIJ”, “”, “KL”, “MNOP”, “QRS”} String string1 … Read more
[ad_1] What you have there is a static method getLibrary() that returns the same instance for all callers. That’s called a Singleton – although there’s better ways to code them. Then again your supposed Singleton (TestLibrary) exhibits methods that when called change internal state – most important, the ErrorHandler. This will cause strange behaviour, especially … Read more
[ad_1] Laying out websites with tables has been frowned upon for around 10 years. For tables, it’s fine, not but for layouts. I would markup some news articles like this: <article> <a href=”https://stackoverflow.com/link-to-article/” title=”article title”> <img src=”link-to-image” alt=”article title”> <h2>Article title</h2> <p>Short description</p> </a> </article> The rest of your question is pretty unclear so would … Read more
[ad_1] In your code, if (number == 10 || 11 || 12 || 13 || 14 || 15 || 16 || 17 ||18 || 19) is a wrong approach. You cannot chain the logical operator like that. As of now, because of the operator precedence, your code is essentially if ( (number == 10) || … Read more
[ad_1] It’s not clear why you’re using your own zip() instead of Python’s zip(), nor why you believe you need zip() at all. You can get this program to work by simplifying the code: fun_string = “””In ___0___, crazy ___1___ with ___2___, ate a meal called ___3___ on a grill””” horror_string = “””In ___0___ owned … Read more
