The DOM element for the <table> will have a rows collection: document.getElementById(‘table-id’).rows.length; You can also select the rows in supporting browsers: document.querySelectorAll(‘#table-id > tr’).length; Or if you’re using a library such as jQuery: $(‘#table-id > tr’).length; 5 solved How to count number of rows in a table when table row is added dynamically [closed]

Assuming you only continues values(0,1,2,3….) int[] A = {0, 0, 0, 0, 1, 1, 1, 2, 2, 2}; // any number and values will work! int max = IntStream.of(A).max().getAsInt(); // gets max value in array int[] counter = new int[max + 1]; for (int i = 0; i < A.length; ++i) counter[A[i]]++; 4 solved Count … Read more
The real simplest way to do this is to use regular expressions, not gobs of split and indexof operations. Regular expressions allow you to specify a pattern out of which pieces of a string can be extracted in a straightforward fashion. If the format changes, or there is some subtlety not initially accounted for, you … Read more
While your code is really messy (and not easy to read) your problem is that you are adding a different instance of Sc to the Pane rather than adding the one you were drawing on: frame.getContentPane().add(new Sc()); Instead you have to add “this” which you can’t do from a static method, but you can create … Read more
And yes , you can just pass with if/else and for loops : a = [[0,0,0,0,0], [0,1,1,0,0], [0,1,0,1,0], [0,0,1,0,0], [0,0,0,0,0]] to_replace = 1 replacement = 9 for i in range(len(a)): for x in range(len(a[i])): if a[i][x] == to_replace: for pos_x in range(i-1,i+2): for pos_y in range(x-1,x+2): try: if a[pos_x][pos_y] != to_replace: a[pos_x][pos_y] = replacement except … Read more
NOTE: Actually technique fabian’s using with Pattern and Matcher is far more correct and elegant, but code provided there is not returning values required by OP . You can use String::split(String). It takes a regular expression to split, so use it, [] means containing one of… so putting | inside will match what you want: … Read more
String constant pool, new object initialization (with new keyword) versus normal initialization of a string? [closed] solved String constant pool, new object initialization (with new keyword) versus normal initialization of a string? [closed]
The function program is not known to the compiler since it’s declared after your main function. You must declare it before like so int program(); // Declares the function program int main() { program(); // function is declared, the compiler knows its return-type, name and parameters return 0; } // Here is the function definition … Read more
MD5 is a cryptographic hash function. Cryptographic hashes are one way functions. You cannot reverse a cryptographic hash value, but you can brute force messages to find one. Brute forcing means trying all possible input strings and then checking if the hash value is correct. This is possible because cryptographic hashes are also computationally unique. … Read more
I think your issue is actually in the use of Reserved Names: $ – jQuery as using that as the configuration results in this Which is what you’re getting, if you change it to ^$ which is what the text box and description on the website says it should be, your code obfuscates fine Reserved … Read more

Don’t use document.write, it does not do what you think it does. What it does not do is write some data at the end of the document. What it does instead, is pipe data into the current write stream. And if there is no write stream, it will make a new one, resetting the document’s … Read more
