decrypted once. It is easy to solve this problem by using BASE64 to encode the Chinese information and then encrypt it. It is also necessary to decode it with BASE64 after decryption. The example is as follows:
String pw= "Chinese";
SYSTEM.OUT.PRINTLN (PW);
Pw=new Sun.misc.BASE64Encoder (). Encode (Pw.getbytes ());
SYSTEM.OUT.PRINTLN (

Let me just say a summary: the idea needs to be expanded.

When talking about the security for service calls, the There are actually a few things to consider. The "All", how did you make sure the data sent over the wire is encrypted? That ' s your a security:always make sure the data that's being sent over the wire is encrypted. After all, unless we ' re working in a intranet environment, anyone could potentially look at the packets that are being SE
Test instructionsGive you a 1~n arrangement, ask if there is a arithmetic progression (length of at least 3)ExercisesI actually thought of the positive solution myself.But I ended up writing a hang, so I read the puzzle again.We have maintained a 01 sequence with a weighted value of subscript.We scan the entire sequence. For each number that is being scanned, we determine whether the 01 sequence is symmetrical by the weighted value of the number as the symmetric point.This sequence is maintained

This article mainly introduces the basics of using js to draw geometric images, such as points, lines, and surfaces. If you need a friend, you may feel a little interesting when following the idea of JS drawing through the brain, so I tried it. JS plotting is a series of articles, which are about points, lines, and surfaces.
First look at the example: http://www.zhaojz.com.cn/demo/draw5.html
