kotlin read file line by line

Here is a code snippet in Kotlin that reads a file line by line, along with explanations for each step:

import java.io.File

fun main() {
    val file = File("path/to/file.txt")  // Step 1: Create a File object with the path to the file you want to read

    file.forEachLine { line ->           // Step 2: Use the forEachLine function to iterate over each line in the file
        // Step 3: Perform operations on each line as needed
        println(line)                     // Example operation: Print each line to the console
    }
}

Step 1: Create a File object with the path to the file you want to read. In the example code, replace "path/to/file.txt" with the actual path to your file.

Step 2: Use the forEachLine function to iterate over each line in the file. This function takes a lambda function as a parameter, which is invoked for each line in the file.

Step 3: Inside the lambda function, you can perform operations on each line as needed. In the example code, the line is simply printed to the console using println(). You can replace this with any other operation you want to perform on each line.

That's it! This code will read the file line by line and perform the specified operation on each line.
