Dynamic update Property file using Scala

Answer 1

Here is the working solution

val pattern = "#Key {0} Value= {1} "
val key = "your_key"
val value = "your_value"

val result = s"#Key ${key} Value=${value}"

val fw = new FileWriter("message_scala.properties", append = true)
try {
  fw.write(result + "\n")
} finally
  fw.close()
}

To read the property file now

val fileInput = new FileInputStream("message_scala.properties")
val properties = new Properties()
properties.load(fileInput)
println("Key value="+properties.getProperty("your_key"))
