java8 lambda

java8出来很久了，在实际环境中很少用到它的特性。但是对lambda已经神往已久。最后添加IntelliJ IDEA配置修改以保证可以编译。

IntelliJ IDEA配置

  1. 安装1.8版本的jdk
  2. 修改Preferences->Build,Execution,Deployment->Compiler->Java Compiler中Per-module bytecode version
    java8 setting compiler
  3. 修改Project Structure->Project Settings->Project中Project SDK和Project language level
    java8 setting project
  4. 修改Project Structure->Project Settings->Module->Source中Language level
    java8 setting modules
