many development teams, each person is often responsible for a core module, and everyone focuses on his own module. Unless a colleague's module affects their own programs, they never communicate with each other. The consequence of this situation is that only one person in each module is familiar with the code inside. If the person is on vacation or--if not--resign, others are helpless. With code reviews, a
2015-10-20Before learning Java knowledge, just follow the code used to jump to learn some, not all of the learning is also wrong into pieces ... Well, what a tragedy!Reasoning, it is necessary to review and finishing, otherwise written out of things really can't read. So, from today's 1.1-point gnawing down.Back to the creation of the class file, and see the fami
This article is the fifth part of the "loose Pair programming" series. (One, two, three, four, five, six, seven, and eight, the ninth and later articles in this series can be found in the topic catalog .)
The loose pair is different from the tight pair. Two people don't always sit together to locate the problem and solve the problem at any time, but sit together for a short time. There are two main tasks at the post-Checkpoint: one is to check whether the results meet the requirements (what to d
Code Review is a commonly used tool in software development, and it is easier to identify problems that are more difficult to find than QA testing, and to help team members improve programming skills, unified programming style, and more.
1. Code review requires the team to have a good culture
Teams need to recognize
; Switch (x) { case 1:system.out.println ("a"); Case 2:system.out.println ("C"); case 3:system.out.println ("B"); default: System.out.println ("D"); }The output is now D. When default is on the last side, no break can end normally. When default is at the top, the default is executed and continues downward. Until you encounter a break or curly brace case 1:case 2:

Java virtual machines can use both instant compilation and bytecode (to achieve platform-independent features), and the use of frequent bytecode sequences will be compiled into machine code for immediate compilation.
The number of bytes in Java is fixed (for portability), unlike C + + (they only determine relative size relationships), and in
