scala函数和方法的差别

想知道什么差别,把代码复制下来运行看结果

// 1 1 2 3 5 8 13
def f(x:Int) :Int=
{
  if(x==)
    return
  else if(x==)
  return
  else
  f(x-)+f(x-)
}
println(f())

// val ff =(cur: Int,x: =>Int) =>
// {
//   if(cur==0)
//   1
//   else if(cur==1)
//   1
//   else
//   // {
//   //   x(cur-1)+x(cur-2)
//   // }
//   0
// }

def funcResult1(message:String) :AnyRef
= (name:String)=>println(message+" : "+name)
//原先写法 def fimcResult1(message:String,name:String)
//{println(message+" : "+name)}
funcResult1("Hello")//("Java")
val result = funcResult1("Hello")//与前面的调用方法相同
//result("java")
println(result);
val x = funcResult1
println(x(""))
