Scala Programming: Compare two strings lexicographically
Scala Programming String Exercise-3 with Solution
Write a Scala program to compare two strings lexicographically.
Note: Two strings are lexicographically equal if they are the same length and contain the same characters in the same positions.
Sample Solution:
Scala Code:
object Scala_String {
def test(str1: String, str2: String): String = {
// Compare the two strings.
val result = str1.compareTo(str2);
// Display the results of the comparison.
if (result < 0) {
("\"" + str1 + "\"" +
" is less than " +
"\"" + str2 + "\"");
} else if (result == 0) {
("\"" + str1 + "\"" +
" is equal to " +
"\"" + str2 + "\"");
} else {
("\"" + str1 + "\"" +
" is greater than " +
"\"" + str2 + "\"");
}
}
def main(args: Array[String]): Unit = {
var str1 ="This is Exercise 1";
var str2 ="This is Exercise 2";
println("String 1: " + str1);
println("String 2: " + str2);
var result = test(str1, str2)
println(result)
println("========================")
str1 = "This is Exercise 1";
str2 ="This is Exercise 1";
println("String 1: " + str1);
println("String 2: " + str2);
result = test(str1, str2)
println(result)
println("========================")
str1 = "This is Blacky";
str2 ="This is Black";
println("String 1: " + str1);
println("String 2: " + str2);
result = test(str1, str2)
println(result)
}
}
Sample Output:
ring 1: This is Exercise 1 String 2: This is Exercise 2 "This is Exercise 1" is less than "This is Exercise 2" ======================== String 1: This is Exercise 1 String 2: This is Exercise 1 "This is Exercise 1" is equal to "This is Exercise 1" ======================== String 1: This is Blacky String 2: This is Black "This is Blacky" is greater than "This is Black"
