compare

问题 I have a problem, I need to compare two inputstreams fast. Today I have a function like this: private boolean isEqual(InputStream i1, InputStream i2) throws IOException { try { // do the compare while (true) { int fr = i1.read(); int tr = i2.read(); if (fr != tr) return false; if (fr == -1) return true; } } finally { if (i1 != null) i1.close(); if (i2 != null) i2.close(); } } But it's really slow. I want to use buffered reads but have not come up with a good way of doing it. Some extra stuff

问题 I wrote recently a folder locking program. My only problem is that when I need to change the password, e.g. I go to section newpass , the program doesn't seem to compare the old to the new password, but just uses any input given which defeats the purpose of having a password because everyone can just change it and than unlock the folder with it. Can someone double check my code and tell me why it is doing it. @echo off title Folder Locker by KBKOZLEV :SETPASS set/p password= <password.txt set

问题 I have two RDD[Array[String]], let's call them rdd1 and rdd2. I would create a new RDD containing just the entries of rdd2 not in rdd1 (based on a key). I use Spark on Scala via Intellij. I grouped rdd1 and rdd2 by a key (I will compare just the keys of the two rdds): val rdd1Grouped = rdd1.groupBy(line => line(0)) val rdd2Grouped = rdd2.groupBy(line => line(0)) Then, I used a leftOuterJoin : val output = rdd1Grouped.leftOuterJoin(rdd2Grouped).collect { case (k, (v, None)) => (k, v) } but

问题 I would like to compare two NSString s. If the user types "Stonehhengge", should get a "border on answer"="almost equals", because the right answer is: "Stonhenge". I would like a percentage of how much one string equals another. If "Stonhenge" is 9 letters, and the typed text contain 8 letters from "Stonhenge", but it's not equal to "Stonhenge", for example: "Stonehange" is not equal to "Stonhenge", but it's near - I'd like to know how near a match the strings are. I only know isEqual: . If

问题 I am writing my own linked list in java that is of generic type instead of using the java collections linked list.
