The significance of logstore in programs of medium size or above is needless to say, especially in some parallel programs, it plays a "Debugger" role. There are many open-source logs
To put it simply, java generic, the dao layer in ssh will simplify the amount of code
In the past, I only heard the teacher say that generics are particularly useful, but I have been using fewer generics for android, but I feel that they are really important, so it took me one afternoon to write a demo. Well, the old rule is:
First, sysout is a tool, but it is difficult to use. The blogger writes a tool class according to his own habits,

This requirement is not difficult for you, you immediately began to write, and soon completed the first version:

final int DEBUG = 0;
public final int INFO = 1;
public final int ERROR = 2;
public final int nothing = 3;
public int level = DEBUG;
public void Debug (String
Note: This is just a procedure for SendMessage, post is similarIf we need to send a message, we call the SendMessage method
Public Final Boolean SendMessage (Message msg)
{return
sendmessagedelayed (msg, 0);
}
This method will call the following method
Public Final Boolean sendmessagedelayed (Message msg, long Delaymillis)
{
if (Delaymil
The common method is to separate out the hours, minutes, seconds, respectively, to judge:
public static Boolean Timecheck (string time, string owner) {
Checks whether the time string times satisfies the format "HH:mm:ss" or "hh:mm" and returns False if the corresponding message is not satisfied
if (Time.equals ("")) {
String msg = owner+ ":" + "Time is EMPTY.";

1. Reference of page elementsThe $ () referenced element of jquery includes methods such as ID, class, element name, element hierarchy, Dom or XPath conditions, and the returned object is a jquery object (set object ), you cannot directly call methods defined by the Dom.
2. Conversion between jquery objects and DOM objectsOnly jquery objects can use methods defined by jquery. Pay attention to the differences between DOM objects and jquery objects. When calling

from createwindow//ncmdshow:the fourth parameter F Rom Winmainshowwindow (hWnd, ncmdshow); UpdateWindow (HWND);So far, this window is not displayed because we have not implemented the WndProc function yet.
The last step of WinMain is the message loop. The purpose of this loop is to listen for messages sent by the operating system. After the application receives the message, it dispatches the message to the WndProc function for processing. The message loop resembles the following:View Copy
