Scala Programming: Check whether a substring appears before a period(.) within a given string
Scala Programming String Exercise-30 with Solution
Write a Scala program to check whether a substring appears before a period(.) within a given string.
Sample Solution:
Scala Code:
object Scala_String {
def test(str1: String, str2: String): Boolean = {
val len = str1.length
var bool: Boolean = false;
if (len < 3)
return false;
for (i <- 0 to len - 3) {
var temp = str1.substring(i, i + 3);
if (temp.compareTo(str2) == 0 && i == 0)
bool = true;
else if (temp.compareTo(str2) == 0 && str1.charAt(i - 1) != 46)
bool = true;
}
return bool;
}
def main(args: Array[String]): Unit = {
var str1 ="testabc.test";
var str2 ="abc";
println("The given string is: " + str1);
println("Is "+ str2 + " appear before a period in the said string? " + test(str1, str2));
str1 ="test.abctest";
str2 ="abc";
println("The given string is: " + str1);
println("Is "+ str2 + " appear before a period in the said string? " + test(str1, str2));
}
}
Sample Output:
The given string is: testabc.test Is abc appear before a period in the said string? true The given string is: test.abctest Is abc appear before a period in the said string? false

Previous: Write a Scala program to check two given strings whether any one of them appear at the end of the other string (ignore case sensitivity).
Next: Write a Scala program to check whether a prefix string creates using the first specific characters in a given string appears somewhere else in the string.
