Scala Console | println, printf and readLine
Console implements functions for displaying the stated values on the terminal i.e, with print, println, and printf we can post to the display. It is also utilized in reading values from the Console with the function from scala.io.StdIn. It is even helpful in constructing interactive programs. Let’s discuss it in detail and also lets see some examples related to it.
- println: It is utilized in putting down values to the Console and moreover computes a trailing newline. we can pass any types as argument to it.
- Print: It is equivalent to println but it does not computes any trailing line. It puts down the data to the beginning of the line.
- printf: This is helpful in writing format strings and also places extra arguments. Example:
GeeksfoGeeks CS_portal Age = 24
- The println and Console.println both are equivalent.
- readLine(): It is a method in which user gives inputs in the pattern of String from the keyboard. Example:
//giving user defined inputs GfG //output by readline Enter the String: Gfg //again giving inputs Nidhi //output Enter the String: Nidhi
- Here, the while loop is infinite in nature and after giving user inputs the variable will contains that (GfG) string and if again we given any input then the variable will contain that (Nidhi) input.
