Scala Programming: Count how many times the substring 'life' present at anywhere in a given string
Scala Programming String Exercise-33 with Solution
Write a Scala program to count how many times the substring 'life' present at anywhere in a given string. Counting can also happen for the substring 'li?e',any character instead of 'f'.
Sample Solution:
Scala Code:
object Scala_String {
def test(stng: String): Int = {
var l = stng.length();
var ctr = 0;
var firsttwo ="li";
val lastone ="e";
if (l < 4)
return 0;
for (i <- 0 to l - 3) {
if (firsttwo.compareTo(stng.substring(i, i + 2)) == 0 && lastone
.compareTo(stng.substring(i + 3, i + 4)) == 0)
ctr = ctr + 1;
}
return ctr;
}
def main(args: Array[String]): Unit = {
val str1 ="live on wild life";
println("The given string is: " + str1);
println("The substring life or li?e appear number of times: " + test(str1));
}
}
Sample Output:
The given string is: live on wild life The substring life or li?e appear number of times: 2

Previous: Write a Scala program to check whether a given substring presents in the middle of another given string. Here middle means difference between the number of characters to the left and right of the given substring not more than 1.
Next: Write a Scala program to add a string with specific number of times separated by a substring.
