Scala: Splitting with Double Quotes (“”) vs Single Quotes ('')

Question

I am splitting a String in Scala with Comma using Double Quotes, like this:

scala> val a = \"a,b,c\"
a: String = a,b,c

scala> a.split(\",\")
res0: Arr         


        

Answer 1

Split by char or escape if you string by string.

Use it as char

scala> a.split('|')
res5: Array[String] = Array(a, b, c)

It works, you need to use escape sequence. Pipe (|) has a special meaning. You need to use escape sequence to say its a normal char.

scala> val a = "a|b|c"
a: String = a|b|c

scala> a.split("\\|")
res2: Array[String] = Array(a, b, c)

with triple quotes

scala> a.split("""\|""")
res4: Array[String] = Array(a, b, c)
