Scala Programming: New string taking specified number of characters from first and last position of a given string
Scala Programming String Exercise-23 with Solution
Write a Java program to create a new string taking specified number of characters from first and last position of a given string.
Sample Solution:
Scala Code:
object Scala_String {
def test(str1: String, n: Int): String = {
str1.substring(0, n) + str1.substring(str1.length - n, str1.length);
}
def main(args: Array[String]): Unit = {
var str1 ="Welcome";
var n1 = 3;
println("The given strings is: " + str1);
println("The given numbers is: " + n1);
println("The new string is: " + test(str1, n1));
str1 ="Scala Programming";
n1 = 4;
println("The given strings is: " + str1);
println("The given numbers is: " + n1);
println("The new string is: " + test(str1, n1));
}
}
Sample Output:
The given strings is: Welcome The given numbers is: 3 The new string is: Welome The given strings is: Scala Programming The given numbers is: 4 The new string is: Scalming
