Your company has commercial Code With Me licenses placed on internal lobby server. In this case, you can activate the license the same way you would activate the IntelliJ IDEA license. You have a commercial Code With Me license, and your company uses the JetBrains floating license server (FLS). However, you if continue facing problems with the activation, activate the license explicitly. You have an active IDE or an offline activation code and your license should be automatically applied to the Code With Me plugin. There are several scenarios in which you might need to activate the Code With Me license manually: In case you have a Community edition, but want to add more guests to your session or make it longer, or your IntelliJ IDEA license is outdated, then you can purchase a separate Premium Code With Me license. If you have the IntelliJ IDEA Community edition, you have also Community version of Code With Me license included in it.Ĭommunity and Ultimate editions of Code With Me license differ with the number of guests that is allowed and time limits of the Code With Me session. If you have an active IntelliJ IDEA subscription or other IDE subscription (except for DataGrip and Rider), you don't need a separate Code With Me license as it's already included in the IDE's license. ![]() We prepared a short video tutorial on how to start working with Code With Me:Ĭode With Me offers different types of subscriptions that you can choose at the JetBrains website. Additionally, it might slow down the performance. The limit is 5, and if it's reached, IntelliJ IDEA will display a popup suggesting to wait. However, there is a limitation on how many participants can actively type together. In this case, participants can quickly change the code and even work on other files of the project at the same time. You can do simultaneous multi editing of your code with other participants. You can achieve that with the Force Others to Follow You mode. Let's say you need to explain a problem and show your team members different parts of your project. You can have a teacher-students scenario where you have many participants who follow you. Unlike classic pair-programming where developers share a single screen and a keyboard, you can work independently and achieve the goal faster. You can do pair-programming, in this case you share your IDE with a single participant and either use the Full sync mode, or follow each other and collaborate on different parts of code. You can start a session with one of the following basic scenarios: Int charOccurrences = StringUtils.A Code With Me shared session involves the interaction between a host and one or more guests. Int stringOccurrences = untMatches(text, stringTarget) // 4 String text = "One fish, two fish, red fish, blue fish" Counting occurrences of a substring or character in a stringĬountMatches method from 3.StringUtils is typically used to count occurrences of a substring or character in a String: import 3.StringUtils NOTE: index n is starting at 0, so the first element is at n=0. To get the nth character in a string, simply call charAt(n) on a String, where n is the index of the character you would like to retrieve (str.charAt(str.length-1)) // Last character "g" You can also use a Stream of codepoints, as of Java 8: int length = str.codePoints().count() Getting the nth character in a String String str = "My String" To count the number of Unicode codepoints in a String, regardless of whether each codepoint fits in a UTF-16 char value, you can use the codePointCount method: int length = str.codePointCount(0, str.length()) Unicode codepoints whose values are ≥ 0x1000 (for example, most emojis) use two char positions. (str.length()) // Prints out 13Ī char in a String is UTF-16 value. ![]() The length is equal to the number of UTF-16 code units (chars) in the string. In order to get the length of a String object, call the length() method on it. ![]()
