[7 of iOS and EV3 hybrid robot programming series] EV3 and iosev3 are controlled through Bluetooth1 Preface in my previous blogs in this series, I found that without iOS jailbreak, I could not use Bluetooth to control EV3 and write a Commander-like program. However, recent studies with Netizens found that the use of External Accessory to achieve Bluetooth transmi

LEJOS+EV3+WIN7 Environment Construction1, build the Java development environmentDevelopment packages that require JDK (note that lejos0.9.0 only supports jdk1.7 's development package, which is not compatible with the pro-Test jdk1.8). For http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html. If the connection address is invalid, please use the "JDK" of the Niang.

in the previous article, we discussed the possibilities of robot development after the combination of iOS and EV3. So, do you want to get together and hacking? to be able to complete the project I am going to talk about next. We need to make the following preparations:1. A Mac performs more than 3 operating systems on Mac OS X 10.9.2, Xcode6.This is the development tool for iOS on Mac. We'll use Xcode to write all the project programs.3, one or two iO

The code block in 4 in Java is summarized as follows:* Add static code block, write a pair of {} in the class to construct a block of code, in the method write a pair of {} is a common code block,* There is also a code block in Java that is a synchronous code block, commonly used in multi-threading, synchronized keyword,* Synchronization code block format is: synchronized (Synchronization object) {}* Static code blocks are executed before the construc

memory) because the JVM executes a static code block when the class is loaded, the static code block is executed before the main method. If a class contains more than one static block of code, it is executed following the code that is defined first, followed by the defined code. Ps: 1 static code blocks cannot exist in any method body. 2 static code blocks cannot directly access static instance variable

Java constructs static code blocks for common code blocks and static code blocks. 1.
