Since Java 7 there is the possibility to define following line Map<String, List<String>> myMap = new HashMap<String, List<String>>(); as Map<String, List<String>> myMap = new HashMap<>(); We had a long discussion about the topic described above. Some of us had the opinion that this is type inference (like var keyword in C#) and the type will be computed at runtime, others thought it's only a simpler way to declare some variable and

问题 According to Oracle, Support for TLS 1.2 first appeared in JDK 7 (2011). For compatibility reasons, it is enabled by default on server sockets but disabled on clients.

JAVA_HOME location is used by most software to detect default JDK location and binaries dir in PATH allows you to use JDK

问题 I'm currently doing a small personal project that needs to display an extremely large amount of data, and I suddenly thought about implementing a form of zoomable user interface to allow the user to navigate around the large amounts of data. I'm aware of existing projects such as ZVTM and Piccolo2d which I'll probably end up using for the job, however I'm also quite tempted to embark upon writing my own. However, I'm a little unsure as how to start. From what I've been reading, it seems that
