A java list of Strings can be converted to a Vector in Scala by utilizing toVector method of Java in Scala. Here, we need to import Scala’s JavaConversions object in order to make this conversions work else an error will occur.
Now, lets see some examples and then discuss how it works in details.
Example:1#
// Scala program to convert Java list // to a Vector in Scala // Importing Scala's JavaConversions object import scala.collection.JavaConversions. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating list of Strings in Java
val list = new java.util.ArrayList[String]()
// Adding Strings to the list
list.add( "Geeks" )
list.add( "for" )
list.add( "Geeks" )
// Converting list to a Vector
val vec = list.toVector
// Displays vector
println(vec)
}
} |
Vector(Geeks, for, Geeks)
Therefore, the resultant output is in same order as stated in the above list and the duplicates are also not deleted.
Example:2#
// Scala program to convert Java list // to a Vector in Scala // Importing Scala's JavaConversions object import scala.collection.JavaConversions. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating list of Strings in Java
val list = new java.util.ArrayList[String]()
// Adding Strings to the list
list.add( "My" )
list.add( "name is" )
list.add( "Nidhi" )
// Converting list to a Vector
val vec = list.toVector
// Displays vector
println(vec)
}
} |
Vector(My, name is, Nidhi)
Here, the stated Strings are not stated in proper order so the resultant output is also not in proper order. As here strings with more number of words are displayed first.
