Scala Programming: Calculate the sum of the numbers appear in a given string
Scala Programming String Exercise-45 with Solution
Write a Scala program to calculate the sum of the numbers appear in a given string.
Sample Solution:
Scala Code:
object Scala_String {
def test(stng: String): Int = {
val l = stng.length;
var sum = 0;
var temp = "";
for (i <- 0 to l-1)
{
if (Character.isDigit(stng.charAt(i)))
{
if (i < l-1 && Character.isDigit(stng.charAt(i+1)))
{
temp += stng.charAt(i);
}
else
{
temp += stng.charAt(i);
sum += Integer.parseInt(temp);
temp = "";
}
}
}
sum;
}
def main(args: Array[String]): Unit = {
val str1 = "it 15 is25 a 20string";
println("The given string is: "+str1);
println("The sum of the numbers in the said string is: "+test(str1));
}
}
Sample Output:
The given string is: it 15 is25 a 20string The sum of the numbers in the said string is: 60
