sonar code review tool for java

Jacoco is a Java Code Coverage statistics tool, see: http://www.eclemma.org/jacoco/ Jacoco is a free Code coverage library for Java, which has been created from the Eclemma team based on the lessons learned F Rom using and integration existing libraries for many years.

In the last section we briefly introduced what Rapid-generate can do, and demonstrated the test code with the tool, which we will apply to our project in conjunction with MySQL. Step One: new Java Project Project, Copy the Generate.xml files and template folders in the Rapid-generate, and introduce the 3 jar packages on which you rely, Freemarker.jar,mysql-connec

Java was originally designed to collect statistics on the number of Java code lines written in its own code lines. The function is very simple. It provides a file path and counts the total number of lines of code, comment lines, empty lines, and so on. Implementation: Typica

In the past, we used the underlying C-API of each database as wrapping to realize the function of data import and export between several heterogeneous databases. However, the code is complex and it is inconvenient to open source. In the afternoon, a simple data extraction program was written in Java to port the MySQL database to Sybase ASE. Put it open-source, put it on: http://code.google.com/p/jmyetl/ to
