For example, you can start a Java variable with a dollar sign or an underscore, but nobody does. Sometimes machine-generated code will prepend a dollar sign or underscore a Java variable to emphasize the non-human origins, but that's about it. Java variable naming conventions For variables,...
Let us now consider some of the more common naming conventions for variables in Java. 1. Rule: Variable Names Are Case Sensitive So, for example, int initialValue is different from int InitialValue or int Initialvalue Consider the following example: class JavaVariable { static void variable...

Here are a few valid Java variable name examples: myvar myVar MYVAR _myVar $myVar myVar1 myVar_1 There are also a few Java variable naming conventions. These conventions are not necessary to follow. The compiler to not enforce them. However, many Java developers are used to these naming co...

名称Java语言编码规范(Java Code Conventions) 译者晨光(Morning) 简介本文档讲述了Java语言的编码规范,较之陈世忠先生《c++编码规范》的浩繁详尽,此文当属短小精悍了。而其中所列之各项条款,从编码风格,到 注意事项,不单只Java,对于其他语言,也都很有借鉴意义。因为简短,所以易记,大家不妨将此作为handbook,常备案头...
9 - Naming Conventions Naming conventions make programs more understandable by making them easier to read. They can also give information about the function of the identifier-for example, whether it's a constant, package, or class-which can be helpful in understanding the code. ...
