PreludeIn this chapter, apart from retaining the original string, array, and other interview questions, we will consciously cut off some interview questions about small and clever numbers, focusing on the clever ideas ", and "wonderful ". This chapter describes the key words of affinity number, "5 million" and "linear complexity ".
Section 1 affinityDescription:Calculate the number of all affinity values le

Chapter 6 bytecode execution methods-Explanation execution and JIT, bytecode jit
NOTE: Refer to "distributed java applications: basics and Practices" and "deep understanding of java virtual machines (version 2)".
1. Two execution methods:
Explain and execute (the bytecode is interpreted and executed at runtime)
Force this mode:-Xint
Compile to machine code for execution (compile the bytecode in

Int a = 12; // Note: This is usually set to a class variable, for example, the segment lock in the Segement and the global lock final ReentrantLock lock in the copyOnWriteArrayList = new ReentrantLock (); lock. lock (); // get the lock try {a ++; // business logic} catch (Exception e) {} finall
battery charge and discharge times. Therefore, in practice the discharge of the battery is not a simple linear relationship. But rather a more complex curve.The following are typical discharge graphs for lithium batteries:In battery management software, the battery life of the squadron is estimated. are often divided into two types:A. Overall endurance (battery life during normal use)B. Specific situations (for example, how long to watch video, how long 3G calls, how long to surf the internet)E

Configurable, which indicates whether the attribute can be deleted by deleting the property, whether the attribute is modified, or whether the property can be modified to an accessor property, and the default is True

Writable, which indicates whether property values can be modified,
code is very simple, but it is implemented using two nested loops.The last block of code uses the Vwlibrary entity, which is based on the Vwlibrary view. The Vwlibrary view joins tables together to flatten them to provide a clearer perspective. When we query each poet's information through the Vwlibraties entity set, only one loop is needed. The output is slightly different because we repeat the poet's name in each poem.The last note in this example is that we did not insert poests,poems and me

Therefore, the scope of the variable A is from the line that defines it, until it ends in the curly brace {}, which is the 4th to 7th Line, leaving the range, and the variable a fails.
Therefore, the above program is compiled failed, the 9th line of code is wrong, variable A in line 7th has been invalidated, it is not possible to use the 9th line
