Scala Programming: Check whether the first two characters present at the end of a given string

Scala Programming String Exercise-24 with Solution

Write a Scala program to check whether the first two characters present at the end of a given string.

Sample Solution:

Scala Code:

object Scala_String {

  def test(str1: String): Boolean = {
   if (str1.length < 2)
    return false;
  else if (str1.substring(0,2).equals(str1.substring(str1.length-2, str1.length)))
    return true;
  else
    return false;
  }

  def main(args: Array[String]): Unit = {
      var str1 =  "educated";	  
      println("The given strings is: "+str1);
      println("If first two characters appear in the last! "+test(str1));
      str1 =  "ABCDEFBA";	  
      println("The given strings is: "+str1);
      println("If first two characters appear in the last! "+test(str1));
  }
}

Sample Output:

The given strings is: educated
If first two characters appear in the last! true
The given strings is: ABCDEFBA
If first two characters appear in the last! false
