Reading Material_ Tuples More

// More about Tuples

// Tuples is a collection of elements. Tuples are heterogeneous data structure. i.e. they can store different kind of data type. Tuples are immutable , unlike the array in scala which is mutable. An Example of Tuple that can holds an in integer, string and a boolean value.

val name = ( 15, "Mehedi", true) // This is tuple of type tuple3
// In Scala the tuples can hold 22 elements . If N is a number the tuples be like 1<=N<=22. If we have increase the elements then we have to use the nested tuples. Nested Tuples are blank tuples that is used inside  a tuples.

println(name._1)
println(name._2)
println(name._3)

// Pattern Matching tuples
val (a,b,c) = ( 15, "Mehedi", true)
println(a)
println(b)
println(c)

//Iterating over a tuple : To iterate over tuple, tuple.productIterator() method is used.
  var name = (15, "chandan", true)

        // The foreach method takes a function
        // as parameter and applies it to
        // every element in the collection
        name.productIterator.foreach{i=>println(i)}

// Converting tuple to string: Converting a tuple to a string concatenates all of its elements into a string. We use the tuple.toString() method for this

val name = (15, "chandan", true)

        // print converted string
        println(name.toString() )

//Swap the elements of tuple: Swapping the element of a tuple we can use tuple.swap Method.
Example :

// Scala program to swap tuple element

val name = ("geeksforgeeks","gfg")  // print swapped element
        println(name.swap)
