Question

Is it possible to make an alias for item of an array in scala? The code below won’t work but something like that.

var str=new ArrayBuffer[String](10)
def alias = str(1)
alias="test"
print(alias)

The code below works and basically what I want to do with the code above. But I don’t want to type str(ALIAS) everytime I use this variable. I want shorter name

var str=new ArrayBuffer[String](10)
val ALIAS=1
str(ALIAS) = "test"
print(str(ALIAS))

Just use a standard setter syntax:

var str= Array("a", "b", "c")

def alias = str(1)
def alias_=(s: String) {
  str(1) = s
}

alias = "test"
print(alias)
