FindBugs is a program that finds bugs in Java programs that look for instances of bug patterns, which are examples of possible errors, and note that findbugs is checking Java bytecode, or *.class files. In fact, it is to look for code defects, many of the bad we write, can optimize the place, it can be checked out. For example, a database connection that is not closed, a lack of necessary null check, redundant null check, redundant if post condition, same conditional branch, duplicate code block

val2 value'Cmd = classmethod (classmd) Run:>>> Mc = MyClass () >>> Mc. smd () >>> Mc. cmd () >>> MyClass. smd () >>> MyClass. cmd () II. Implementation with decorators in Python 2.4 and laterThe decorator uses the @ operator, for example: class MyClass: Val1 = 'value 1' Def _ init _ (self ): Self. val2 = 'value 2' @ StaticmethodDef staticmd ():Print 'static method, unable to access val1 and val2' @ Classm

, because in subsequent calls, the instance is not known. However, instance functions can access class variables.4. Modify the range of variables class is class class is class is a static methodIs the result of the output in the function1. class is class class is class isclass variableThis is the result of function2, and the class variable has changed.If you modify a variable through a class method, the class variable in all instances is modified,

and change the static fields of a class, they do not have a money field in their own memory, so they go through the class pointers to the class memory, but when they are found, will open up a space in your own memory space to store the modified results for this static field. Therefore, the static fields in the class are not changed at this time, and the money fi
