![format_png][]

IntelliJ把我的项目默认使用1.5版本的编译器。然后就手动把IntelliJ的Java编译器的版本改为了1.8。一共有三个地方要改。

# 1、文件->设置(ctrl+alt+s) #

# ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hlbGxvd29ybGQwOTA2_size_16_color_FFFFFF_t_70][] #

# 2、文件->项目结构（ctrl+alt+shift+s） #

## 2.1 ##

## ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hlbGxvd29ybGQwOTA2_size_16_color_FFFFFF_t_70 1][] ##

## 2.2 ##

## ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hlbGxvd29ybGQwOTA2_size_16_color_FFFFFF_t_70 2][] ##
