Kotlin Input/Output

 

Kotlin Input : It is used to flow byte streams from user input such as keyboard to system's main memory. There are two ways in which we can take input from the user.

1. readLine() : It takes the input from the user as a string

    var line = readLine()

2. Scanner Class :

    var scanner = Scanner(System.'in')

    var number = scanner.nextInt()

Kotlin output : It is used to display output on the console.

    1. print() : This simply prints the message which is inside double quotes.

    2. println() : This print s the message and moves to the next line.

NOTE : If we see the implementation of print() and println() function, internally the implement System.out.print() and System.out.println() from java respectively.
