JAVAOO1-4 chapter learning focus
Data types in JAVA: basic types, reference types Basic types: numeric, byte, integer, long integer, character, Boolean, etc.; Reference type: class, interface, array; Notes on using identifiers: 1. Cannot start with a number 2. Case sensitive 3. Cannot quote keywords 4. CamelCase (first letter capitalized) 5. Pascal’s nomenclature (first letter primary, other words capitalized) Application of π π : final data type constant name (all uppercase) = constant value Input in java Header file: import java.util.Scanner public{ Scanner input (nameable) = new Scanner(System.in) Input: System.out.println(“Please enter: “); int (data type) num (optional name) = input.nextInt() input.nextInt();(receive shaping input) input.nextDouble();(receive Double type input) input.next();(receive string type input) } The minimum value of an integer in java: Integer.MIN_VALUE; (the green part must be capitalized) Random numbers in java: (int)(Math.random()*100); String comparisons in java are equal: Example: if(“name”.equals(variable name)) Fully qualified name:package name.package name.class name.fully qualified name The package name must be the first executable statement in the source file Important words: public public protected protected private private Method: public String toString(){ return “name”+name+”sex” +sex + “age” + age } Access modifier return value type method name (parameter list){ Method body: function code block to be implemented } Create object: Example: Create a…
DATE values exported as binary
If “export binary data as hex” is checked whenexporting data, DATE and DATETIME field values areexported as hexadecimal rather than as strings. Observed with MySQL versions 4.1.4-gamma and5.0.1-alpha, running on IIS 5.0/Win2K. I don’t believe that this is the correct behavior, norcan I see it being useful, since MySQL is going to beexpect these to be strings for purposes of import.

Minidump method to preserve the crash site of the program
The introduction part is transferred from https://www.cnblogs.com/lisuyun/p/5245609.html Parts of the program are original. Minidump way to save the program crash site When using C++ to develop applications under the Windows platform, the last thing you want to see is that the program crashes. To solve the bugs that cause problems, the most difficult thing is to debug the release version. Because the release version lacks a lot of debugging information, not to mention that it is generally released for use by users, it is difficult to retain and reproduce the scene of the crash. There are currently some ways to solve it: crash address + MAP file; MAP file; SetUnhandledExceptionFilter + Minidump. This article focuses on the SetUnhandledExceptionFilter + Minidump method. 1. Minidump file generation 1. Minidump concept minidump (small memory dump) can be understood as a dump file, which records the minimum useful information that can help debug crash. In fact, if you select “Small memory dump (64 KB)” in System Properties -> Advanced -> Startup and Recovery -> Settings -> Write Debug Information, when the system stops unexpectedly, it will be in C:\ A file with a .dmp suffix is generated under the Windows\Minidump\ path. This file is…

One ： first look at manual debugging with ndk-gdb This method is only suitable for manually writing Android.mk，because we need to manually build the debug version. so file. For details, please refer to my previous article. 1 AndroidManifest.xml android:debuggable is set to true 2 Switch to the jni directory and execute ndk-build NDK_DEBUG=1 This will generate The library file of the debug version ， also has a gdbserver and gdb.setup 3 Run the installation and startup program 4 Switch to your src/main directory and execute ndk-gdb This reports a Error ： ERROR: Could not find gdb.setup under /Users/lesliefang/AndroidStudioProjects/MyApplication/app/src/main/libs/Then put gdb under armeabi. Copy the setup file to ./libs Re-execute ，result another error： ERROR: Non-debuggable application installed on the target device. Please re-install the debuggable version! This is because the runtime studio did not package the gdbserver into the apk ， what to do， decompile and package it manually& #xff0c; Just repackage the signature Install, start and run ， Execute ndk-gdb again successfully 2 IDE debugging, android studio’s current debugging support for NDK is only in the experimental stage For details, please refer to http://tools.android.com/tech-docs /new-build-system/gradle-experimental Tossed a lot ， can also be debugged Students who are familiar with java are…
How JavaGC works
Reprinted to ： https://blog.csdn.net/d6619309/article/details/53358250 It is well known that ， Java programs do not need to be like C++ The program handles the recovery and release of memory by itself in the program. This is because Java adds a garbage collection (GC) mechanism on the JVM virtual machine ， to trigger garbage collection at the right time ， recycle and release unnecessary memory space ， to avoid unlimited OOM caused by memory growth. As a qualified Java programmer，It is necessary to understand Java GC related knowledge. On the one hand, mastering GC knowledge can help us quickly troubleshoot online problems caused by JVM， on the other hand, it can also help us properly tune the JVM before the release of Java applications，improve the execution efficiency of applications, reliability and robustness. This article will introduce the following points： Java heap memory structure Generational recovery algorithm Garbage collector GC log JVM parameter usage The virtual machine discussed in this article is the default The HotSpot virtual machine used by the JDK. 1. Java heap memory structure In order to understand the knowledge points in the following chapters， we should First have a certain understanding of the Java heap memory structure division. Java…
Hybrid deployment practice of TiDB cluster in production environment
1. Background Due to various off-site factors, we cannot freely choose the ideal hardware environment, and the current hardware configuration of a single physical machine is often higher than the demand. In order to plan resources more reasonably In many cases, a server cannot “luxury” deploy only one instance, but will consider deploying TiDB or TiKV on a single machine with multiple instances. This requires building a highly available and high-performance TiDB cluster as much as possible in the existing environment. This article mainly shares the process of hybrid deployment of TiDB clusters in an actual production environment for your reference. 2. Hardware configuration 10 physical machines, each with 56C 384G 4 pieces of 2TB NVME hard disk. Monitoring, HA and other machines can use virtual machines, so they are not included in the purchase budget. The configuration is up to standard, but due to various factors, it was originally expected that the hardware of one cluster would need to be mixed and deployed with two sets of clusters. 3. Cluster topology planning Cluster 1 Instance IP TiDB & PD 10.0.0.1 TiDB & PD 10.0.0.2 PD 10.0.0.3 10.0.0.4 Tikv *2 10.0.0.5 Tikv *2 10.0.0.6 Tikv *2 10.0.0.7 Tikv *2 10.0.0.8…
