In recent years, the Android system has become very popular. At present, more than 0.5 billion Android phones are in use worldwide, and 1.3 million new Android devices are activated every day. That is to say, about 3/4 of the smartphone market share belongs to Google and its operating systems.
But do you know? Android not only runs on smartphones and tablets, but also on Google's Android platform. Here, we have collected ten devices running Android. Which one do you think is the coolest?

the microcontroller is not the focus of the project. This has become a part of the arm world--arduino Due platform is equipped with arm-basedCortexof the-M3 processorAtmelsam3x8e MCU. The standardization of the processor architecture in the MCU makes the ecosystem that supports it even more prosperous. Further development is the use of a more advanced scripting language such as Python, or even a WEB programming model such as JAVASCRIPT, for microcontrollers such asTessel. Application Processor

To sort the list, you can let the entity object implement the comparable interface , and override the CompareTo method to sort by an attribute, but this is a single way to sort by a fixed attribute, without change. By following this method, you can dynamically specify that the list is sorted by one of the attributes, the example is simple, see the code to understand.

language product delivery medium. class file StructureThe class file is a set of binary streams that are based on 8-bit bytes, and each data item is arranged in a compact order in the class file without any delimiters, so that almost all of the content stored in the class file is the necessary data for the program to run, and no gaps exist. When a data item that requires more than 8 bytes of space is encountered, it is stored by splitting several 8-bit bytes in front of the high-order.Accord
is represented by all nonzero integers. As with the Java language, the basic types of Java virtual machines have a range of domains that are consistent everywhere, regardless of the host platform, a long is always a 64-bit, twos-complement signed integer in any virtual machine.For ReturnAddress, this basic type is used to implement the finally clause in a Java program, which the Java programmer cannot use, and whose value points to the opcode of a virtual machine instruction.2 architectureIn th

It can be seen from here that the space occupied by the consortium depends not only on the widest member, but also on all members, that is, its size must meet two conditions: 1 the size is large enough to accommodate the widest member, and 2 the size can be divisible by the size of all the base data types it contains.
