Scala Programming: Create a new string taking the first 3 characters of a given string and return the string with the 3 characters added at both the front and back
Scala Programming Basic Exercise-12 with Solution
Write a Scala program to create a new string taking the first 3 characters of a given string and return the string with the 3 characters added at both the front and back. If the given string length is less than 3, use whatever characters are there.
Sample Solution:
Scala Code:
object scala_basic {
def test(str1: String): String =
{
if (str1.length < 3) str1 * 3
else str1.substring(0, 3) + str1 + str1.substring(0, 3)
}
def main(args: Array[String]): Unit = {
println("Result: " + test("Scala"));
println("Result: " + test("abcd"));
println("Result: " + test("ab"));
println("Result: " + test("a"));
}
}
Sample Output:
Result: ScaScalaSca Result: abcabcdabc Result: ababab Result: aaa
