projects agreed by the company code. If improving code quality is the primary goal, then PMD is a good choice. But if you want more features and really use tools to modify the code, you should try jalopy. jalopy, Jalopy is an easy to configure source code format program that detects and fixes a large number of custom bugs in Java code. Jalopy is more like a code-builder than an inspector. Jalopy's plug-in

Do you encapsulate a class (Vo) or take it slowly?Put back the class type, y

It's so easy to use java to convert numbers in uppercase. Often on business trips, often fill in invoices, sometimes the network is not good, the number is not enough As a result, a portable small application was born. That's right. I only want to make it convenient for a moment ~ There is a number 1314521.94 I want to convert to uppercase But it is a little long and has a decimal point. So I took

The greatest benefit of Java reflection is the ability to get the structure, member variables, and instantiation of a class during run time.The following are specific usage scenarios: if we had two programmers, a programmer would need to use the class written by the second programmer while writing the program, but the second programmer did not complete the class he wrote. So can the first programmer's code be compiled? This is not possible by compilin
