The IDEA @Override below how to remove red wavy line

Test, and will not affect the operation! 

Get rid of the red line!

file - seting - java compiler - the two version were changed to 1.8 (because my jdk 1.8)!

 

file - project struture   -   modules - language level -- 8 ! 

These two steps are removed!
