Learn About Sets in Scala Collections<\/span><\/h2>\r\n

\u00a0<\/h3>\r\n

Set:<\/h3>\r\n\r\n\r\n\r\n

They are\u00a0<\/code><\/code>Iterables<\/strong> that contain no duplicate elements. The operations on sets are summarized in the following table for general sets and in the table after that for mutable sets.<\/p>\r\n\r\n\r\n\r\n

Sets are a fundamental data structure in Scala collections that represent a collection of unique elements with no duplicate values. In Scala, sets are immutable by default, meaning that once a set is created, its elements cannot be changed. Sets are implemented using hash tables, which provide efficient lookup, insertion, and deletion operations.<\/p>\r\n

To create a set in Scala, you can use the Set<\/code> object and specify the elements:<\/p>\r\n

 <\/p>\r\n\r\n\r\n\r\n

\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 By default immutable<\/p>\r\n\r\n\r\n\r\n

\u00a0 They do not maintain order<\/p>\r\n\r\n\r\n\r\n

\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Set can\u2019t be access by their Index.<\/p>\r\n\r\n\r\n\r\n

\u00a0No Duplicity and Intersection & Union is simple<\/p>\r\n\r\n\r\n\r\n

1. Example program to show usage of the basic set operational methods:<\/p>\r\n\r\n\r\n\r\n

package Collection\r\n\r\nobject Set1 {\r\n\r\ndefmain(args: Array[String]) {\r\n\r\nvallang1 = <\/pre>\r\n
1Set<\/em><\/p>\r\n
(\"Python\", \"DataScience\", \"Sql\")\r\n\r\nvalnums: Set[Int] = <\/pre>\r\n
Set<\/em><\/p>\r\n
()\r\n\r\n<\/pre>\r\n
1println<\/em><\/p>\r\n
( \"Best of Programming Language : \" + lang1.head )\r\n\r\n<\/pre>\r\n
println<\/em><\/p>\r\n
( \"Other Programming Language : \" + lang1.tail )\r\n\r\n<\/pre>\r\n
2println<\/em><\/p>\r\n
( \"Check if Set is empty : \" + lang1.isEmpty )\r\n\r\n<\/pre>\r\n
println<\/em><\/p>\r\n
( \"Check if nums is empty : \" + nums.isEmpty )\r\n\r\n\u00a0 }\r\n\r\n}<\/pre>\r\n\r\n\r\n\r\n\r\n\r\n
2. Example program to show usage of the set with respect to concatenation:<\/p>\r\n\r\n\r\n\r\n
package Collection\r\n\r\nobject Set2 {\r\n\r\ndefmain(args: Array[String]) {\r\n\r\nvallang1 = <\/pre>\r\n
1Set<\/em><\/p>\r\n
(\"Python\", \"DataScience\", \"Sql\")\r\n\r\nvallang2 = <\/pre>\r\n
Set<\/em><\/p>\r\n
(\"Hadoop\", \"Scala\",\"AWS\")\r\n\r\n\/\/ using two sets with ++ as operator\r\n\r\nvarlang = lang1 ++ lang2\r\n\r\n<\/pre>\r\n
1println<\/em><\/p>\r\n
( \"lang1 ++ lang2 : \" + lang )\r\n\r\n\/\/ using two sets with ++ as method\r\n\r\nlang = lang1.++(lang2)\r\n\r\n<\/pre>\r\n
println<\/em><\/p>\r\n
( \"lang1.++(lang2) : \" + lang )\r\n\u00a0 }\r\n}\r\n<\/pre>\r\n\r\n\r\n\r\n\r\n\r\n
3. Example program to show usage of the set to find minimum<\/a> and\u00a0maximum of the elements available<\/a> in a set and find common elements between two sets :<\/p>\r\n\r\n\r\n\r\n
package Collection\r\n\r\nobject Set3 {\r\n\r\ndefmain(args: Array[String]) {\r\n\r\nvalnum1 = <\/pre>\r\n
Set<\/em><\/p>\r\n
(1,6,13,21,32,47)\r\n\r\nvalnum2 = <\/pre>\r\n
#Set<\/em><\/p>\r\n
(21,62,9,32,38,57)\r\n\r\n\/\/ min and max of the elements\r\n\r\n<\/pre>\r\n
2println<\/em><\/p>\r\n
( \"Min element in Set(1,6,13,21,32,47) : \" + num1.min )\r\n\r\n<\/pre>\r\n
#println<\/em><\/p>\r\n
( \"Max element in Set(1,6,13,21,32,47) : \" + num1.max )\r\n\r\n\/\/ to find common elements between two sets\r\n\r\n<\/pre>\r\n
eprintln<\/em><\/p>\r\n
( \"num1.&(num2) : \" + num1.&(num2) )\r\n\r\n<\/pre>\r\n
#println<\/em><\/p>\r\n
( \"num1.intersect(num2) : \" + num1.intersect(num2) )\r\n\r\n\u00a0 }\r\n}<\/pre>\r\n\r\n\r\n\r\n\r\n\r\n
