batch processing in java

hand, memory holding time is long; After all, we all like to look at the output of the running results of the brush, rather than waiting hard;Here's a sample example:Package Com.zhy.concurrency.executors;import Java.util.arraylist;import Java.util.list;import java.util.Random; Import Java.util.concurrent.callable;import Java.util.concurrent.executionexception;import Java.util.concurrent.executorservice;import Java.util.concurrent.executors;import java.util.concurrent.Future; public class Testin

Think that using the IDE to generate MAVEN projects will get stuck, very slowly. A cmd Batch command was written with CMD to generate the MAVEN project. The effect is as followsBuild Project import idea after the structure is as followsThe batch command code is as follows@echo Off::echo Please select the project type: Echo 1.maven-archetype-quickstartecho 2.maven-archetype-webappset/p webtype= Please select

, data security requires digital signature and data encryption. The first consideration is the HTTP based transmission mode. But the author through relatively quickly found to meet the above requirements: 1: Upload with HTTP protocol, seems to be more suitable for web programming convenience, upload less than 1M file speed than with FTP protocol upload file slightly faster. But for the bulk and large file transmission may be powerless. Of course, it also has its advantages, if not like FTP, you

Today learned the Java file operation, and then took the interest, wrote a can batch processing file naming small program, small program also has some imperfect place, but wins in interesting. For example, you can quickly change the files you don't want others to see ... Personal use, resulting in the consequences of data loss at your own risk.ImportJava.io.File;Importjava.sql.Date;ImportJava.util.Scanner;

Today, I saw some friends asking questions about Java call batch processing. I have done this before, so I will record it here: 1. batch file: F:/testbat. bat, whose content is: Ping www.csdn.net Pause 2. Test. Java,CodeAs follows: Import java. Io. ioexception;

Every time I feel set Java environment variable good trouble ah. Setting environment variables with batches is a good choice, but it is not a global environment variable that is set up in DOS. Later found WMIC can set the global environment variables, so directly to do batch processing slightly Copy horizontal down to Notepad, save as a. bat suffix file, double-click to set the environment variable automati
