Alternative to println()?-CodePudding

If we don't have the println() function, is there any alternative or a way to write your print function?

CodePudding user response：

If you right-click on println in IntelliJ, you can Go to... -> Implementation(s) and see how Kotlin does it "under the hood". It's a bit verbose but not that complicated. Ultimately it's using a BufferedWriter to write to the Standard Output stream.

You can replicate this yourself with something like:

import java.io.BufferedWriter
import java.io.OutputStreamWriter


fun main() {
    val writer = BufferedWriter(OutputStreamWriter(System.`out`))
    writer.write("No println here")
    writer.newline()
    writer.flush()
}
