How to Escape Special Symbols in Scala String at Runtime?

Handling special symbols’ interior strings is an average project in Scala, especially whilst interacting with dynamically created cloth or consumer enter. If special symbols like quote marks, backslashes, or newline characters are not effectively escaped, they could bring about syntax errors or unexpected conduct. This article discusses how to escape special symbols in Scala string at runtime.

Using replace Method

Below is the Scala program to escape special symbols in Scala string using the replace method:

Scala

object GFG {
  def main(args: Array[String]): Unit = {
    val input = "Hello, \"Scala\"!";
    val escapedInput = input.replace("\"", "\\\"");
    println(escapedInput);
  }
}

Output

Hello, \"Scala\"!

Explanation:

The input string in this example contains double charges. To break out the double quotes, we utilize the update characteristic to update every instance of ” with “.

Using Backslash

Below is the Scala program to escape special symbols in Scala string using Backslash:

Scala

object GFG {
  def main(args: Array[String]): Unit = {
    val input = "This is a backslash: \\, and this is a newline:\nHello!";
    val escapedInput = input
      .replace("\\", "\\\\")
      .replace("\n", "\\n");
    println(escapedInput);
  }
}

Output

This is a backslash: \\, and this is a newline:\nHello!

Explanation:

This code instance indicates a string input with a newline individual and a backslash. We break out every backslash with and every newline individual with n the usage of the update technique.

Using Triple Quotes (“””)

Below is the Scala program to escape special symbols in Scala string using triple quotes:

Scala

object SpecialStringExample {
  def main(args: Array[String]): Unit = {
    val specialString = """This is a string with a special symbol: \"""
    println(specialString)
  }
}

Output:

This is a string with a special symbol: \"

Creating Multi-line Text using stripMargin

You can create a multiline string in Scala and use the stripMargin method to escape special marks. This method removes white leads from each character based on the specified margin character (by default, |).

Below is the Scala program to escape special symbols in Scala:

Scala

val multiLineString =
  """
    |This is a multi-line string
    |with special symbols: \"
    |""".stripMargin

println(multiLineString)

Output:

This is a multi-line string
with special symbols: \"

Conclusion

It is crucial to break out specific symbols from Scala strings at some stage in runtime so that you can assure accurate code interpretation and execution. Scala offers versatile strategies for effectively dealing with unique symbols, whether you select to use raw strings or the replace characteristic. With the techniques defined in this article, you could deal with unique symbols to your Scala strings with self assurance and steer clean of any sudden behavior or syntactical troubles.
