After considering your String It made me to add one thing String s2= “10 = On Battery “; String s[]=s2.split(“=”); int i=Integer.parseInt(s[0].trim());<———– use trim() otherwise you will have “10 ” with whitespace ^ But…… I have to split the numeric value 10 and words “On Battery”(Including the space in between them) String a=s2.split(“=”)[0];//”10 ” String … Read more
I am unsure about the language, but for C# you can use the following: string s1 = “1 AND 1 OR 1”; string s2 = s1.Replace(“AND”, “,”).Replace(“OR”, “,”); Console.WriteLine(s2); Which doesn’t use regular expressions. If you want an array, you can use the following: string s1 = “1 AND 1 OR 1”; string[] s2 = … Read more
You could stream the array, and filter using String::contains. String[] words = {“bad”, “bat”,”hat”}; String filter = “at”; List<String> list = Stream.of(words) .filter(word -> word.contains(filter)) .collect(Collectors.toList()); System.out.println(list); solved Java Array Searching [closed]
String firstblock = “If debugging is thae process of removing software bugs, then programming must be the process of putting them in. Most good programmers do programming not because they expect to get paid or get adulation by the public, but because it is fun to program.”; byte[] bytes = firstblock.getBytes(); StringBuilder binary = new … Read more

I think you should develop more on your fundamentals, and try out your own code before asking a question here. I guess what you are trying to achieve can be done like this. import json with open(“example.json”, “r”) as f: json_content = json.load(f) message = json_content[“message”] variable = “var” print(message.format(variable=variable)) # prints # this is … Read more
This should do it. What it does is that it gets a string to look at, gets a character to look at, iterates through the string looking for matches, counts the number of matches, and then returns the information. There are more elegant ways to do this (for example, using a regex matcher would also … Read more
If you don’t have a private key. You can’t decrypt. If you don’t have an encryption method and don’t have a key. You super can’t decrypt. There’s no method to figure out what encryption was used. And even if you did know unless it was md5 (I can tell by looking it isn’t) or something … Read more
The row_string = “” in the outer loop creates a new, empty string every time the outer loop runs. So when the inner loop starts to run, the row_string is an empty string. Now each time the inner loop runs, something gets added (appended) to that empty string, namely the value of product casted into … Read more

string is an alias in C# for System.String. So technically, there is no difference. It’s like int vs. System.Int32. As far as guidelines, it’s generally recommended to use string any time you’re referring to an object. e.g. string place = “world”; Likewise, I think it’s generally recommended to use String if you need to refer … Read more
ECMAScript 6 introduced String.prototype.includes: const string = “foo”; const substring = “oo”; console.log(string.includes(substring)); // true includes doesn’t have Internet Explorer support, though. In ECMAScript 5 or older environments, use String.prototype.indexOf, which returns -1 when a substring cannot be found: var string = “foo”; var substring = “oo”; console.log(string.indexOf(substring) !== -1); // true 6 solved How to check whether … Read more
== tests for reference equality (whether they are the same object). .equals() tests for value equality (whether they are logically “equal”). Objects.equals() checks for null before calling .equals() so you don’t have to (available as of JDK7, also available in Guava). Consequently, if you want to test whether two strings have the same value you … Read more
java.sql.Timestamp (a subclass of java.util.Date) uses milliseconds for time while the Unix timestamp counts seconds. If you have a Unix timestamp you need to multiply it by 1000 (and divide by 1000 to get a Unix timestamp from a Java Date). solved Java / Scala – how to convert string to long?
