One 、Lambda expression
Two 、 Important features
- l Type declaration ： Parameter types do not need to be declared , Compiler can identify parameter values uniformly .
- Parameter parentheses ： A parameter does not need to define parentheses , But multiple parameters need to define parentheses .
- Curly braces ： If the body contains a statement , You don't need braces .
- Return keyword ： If the body has only one expression return value, the compiler returns the value automatically , Braces need to specify that the expression returns a number .
3、 ... and 、 Access variables
3.1 Member variables
3.2 local variable
