scala> def t = (t1: Int, t2: Int)=>println("scala")
t: (Int, Int) => Unit
scala> def t = (t1: Int, t2: Int)=>{println("scala");1+2}
t: (Int, Int) => Int
scala> def t = (t1: Int, t2: Int)=>{println("scala"); t1+t2}
t: (Int, Int) => Int
scala> def t = (t1: Int, t2: Int)=>{println("scala"); t1+"12"}
t: (Int, Int) => String
execute the code below
def t=(t1:Int,t2:Int)=>{println("scala");t1+"t3"}
println(t(1,2))
print result:
1t3
Why doesn't println in anonymous function print out???????
