i'm writing high-performance nashorn application, , i'd find equivalent new string[]{"foo", "bar", "noise"} within javascript. cost of converting javascript array java array prohibitively expensive, shows on every flame graph. the best i've found point is: {var stringarray = java.type('java.lang.string[]');"); var arr = new stringarray(3)); var arr[0] = 'foo'; var arr[1] = 'bar'; var arr[2] = 'noise'; arr; } but that's super ugly. best syntax available me? thanks! you can using java.to() : java.to(["foo", "bar", "noise"],"java.lang.string[]"); if code works (it me, tested jjs 1.8.0_51), can create function ease code readability. this: function tojavastringarray(a) { return java.to(a,"java.lang.string[]"); }

i'm working on interview workbook , doing problem: implement function compress string using counts of repeated characters (aabcccccaaa become a2blc5a3). return original string if "compressed" not smaller original. a solution found counts size of compressed string before else. i've tried tracing through helper function don't understand logic of line. any deciphering great! : size = size + 1 + std::to_string(count).length(); count int number of repeated characters in c++11, to_string lets append append ints strings. so, a+1 a1. better solution: int countcompression(const string& str) { if (str.length() == 0) return 0; char prev = str[0]; int size = 0; int count = 1; (int = 1; < str.size(); i++) { // repeated char if (str[i] == prev) count++; // unique char else { prev = str[i]; size = size + 1 + std::to_string(count).length(); ...

suppose set variable, $i = 0, then "-$i-" => "-0-" "-$($i)-" => "-0-" the above expect, fails: "-$(++$i)-" => "--" # expected "-1-" however, expressions work. example: "-$(pwd)-" => "-c:\temp-" so what's going on here? according documentation , expected behavior the increment operator (++) increases value of variable 1. when use increment operator in simple statement, no value returned. view result, display value of variable, follows: c:\ps> $a = 7 c:\ps> ++$a c:\ps> $a 8 to force value returned, enclose variable , operator in parentheses, follows: c:\ps> $a = 7 c:\ps> (++$a) 8 the shortest way around following statement: "-$((++$i))-" #=> -4- since set of parentheses tell return value, opposed execute statement.
