Java has evolved over the years, with each new version introducing new features and improvements. The language level refers to the version of the Java language specification that a particular codebase complies
对此我们总结language level:限定项目编译检查时最低要求的 JDK 特性。 现在假设我们有一个项目代码使用的 JDK 8 新特性:lambda语法,但是 JDK 选择的却是 JDK 7,即使language level选择了8 - Lambdas,type annotation etc.,也是没有多大意义的,一样会编译报错。 Module 下的 SDK 和 language level 对于大型项目,...

If the code turned out to be larger than 64K (which is not easy to do in assembly language), we would move to the Medium model. These same memory models also apply to Microsoft's high-level DOS language compilers. If you are writing a MASM program to work with another high-level ...
<maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> </properties> [...] </project> 上面两种方法设置一个即可,设置完,当我们再刷新 Maven 项目的时候,Java Language Level 就不会再变动了。
