braces

问题 I keep getting this message when I try to compile: Reached End of file while parsing Anyone know why? The only thing that I have figured out is that it has something to do with my curly braces. I have tried to move braces around, add them, and delete them but I can not figure this out. The error occurs in the last line of code. import java.awt.event.ActionEvent; //Next group of lines import various Java classes import java.awt.event.ActionListener; import javax.swing.JButton; import javax

问题 I am getting ready for a java certification exam and I have seen code LIKE this in one of the practice tests: class Foo { int x = 1; public static void main(String [] args) { int x = 2; Foo f = new Foo(); f.whatever(); } { x += x; } // <-- what's up with this? void whatever() { ++x; System.out.println(x); } } My question is ... Is it valid to write code in curly braces outside a method? What are the effects of these (if any)? 回答1: Borrowed from here - Normally, you would put code to

问题 is there a regular expression to match the content within braces. For example with the following: d = {'key': {'a': [1,2,3]}} I would want to match {'key': {'a': [1,2,3]}} and {'a': [1,2,3]} , but not {'key': {'a': [1,2,3]} 回答1: In classical regular expressions, this is impossible - DFAs can't parse nested pairs. There are ways to do it with extended regular expressions, such as recursive expressions that are allowed in some regex engines (such as Perl regex), but they're not always pretty. (

问题 When I try to compile the code I get an error that says else without a previous if : // Fibonacci series using recursion #include <iostream> using namespace std; int fib (int n); int main() { int n, answer; cout << "\n\n\t\tEnter number to find: "; cin >> n; cout << "\n\n"; answer = fib(n); if(n < 3 && n > 1) cout << answer << " is the " << n; cout << "nd Fibonacci number\n"; { if(n < 3) cout << answer << " is the " << n; cout << "st Fibonacci number\n"; else cout << answer << " is the " << n

问题 Intro Im developing PHP in NetBeans IDE 7.2 (Build 201207171143) and I love the formatting to clean up my code in my custom format. At the moment I work in a group with colleagues. Some of my colleagues are used to write single line statement without braces (I think this is bad practice). Examples What my colleagues do: <?php if($stackoverflow == 'Cool') echo 'Stack Overflow is Cool!'; ?> What I want when I format the code. <?php if($stackoverflow == 'Cool') { echo 'Stack Overflow is Cool!';

问题 I have a sort of mini parsing syntax I made up to help me streamline my view code in cakephp. Basically I have created a table helper which, when given a dataset and (optionally) a set of options for how to format the data will render out a table, as opposed to me looping though the data and editing it manually. It allows the user to be as complex or as simple as they like, it can get pretty powerful. However, In order to achieve this I had to make a simple parsing syntax. As a quick example

问题 We use braces {} for variable expression like NAME="test" FILE_NAME=${NAME}file But I don't understand in which scenarios we use brackets () Say nslookup $(hostname) works only with () brackets. Can someone explain? 回答1: Minor nitpick first: Brackets [] Parentheses () Braces {} (Double) Quotation marks "" (Single) Quotation marks (apostrophes) '' Backticks `` (Same as the tilde ~ key) Braces are used in BASh scripts for complex variable expansion. Consider string concatenation: STR="hello"
