Scala – StringBuffer.append() Method

Here, we will create a string using the StringBuffer class and then we will append an integer number to the string using the append() method.

Scala code to demonstrate the example of StringBuffer.append() method

The source code to demonstrate the append() method with the StringBuffer class is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to demonstrate
// the append() method with StringBuffer class

object Sample {
  def main(args: Array[String]) {
    val str = new StringBuffer("Lucky Number: ");

    //Appending a number to an immutable string
    str.append(123);

    println(str);
  }
}

Output

Lucky Number: 123

Explanation

In the above program, we used an object-oriented approach to create the program. And, we created an object Sample. Here, we defined main() function. The main() function is the entry point for the program.

In the main() function, we created an immutable string str using the StringBuffer class. Then we appended an integer number 123 to string str using the append() method. After that, we printed the result on the console screen.
