Scala String compareTo() method with example
The compareTo() method is utilized to compare a string with another string.
Some points to remember:
- Here, If a string(S1) is same as string(S2) in comparison then this method returns zero.
- If S1 is less than S2 then a negative number is returned which is the difference of character value.
- If S1 is greater than S2 then a positive number is returned.
Method Definition: int compareTo(String another String)
Return Type: It returns an integer.
Example #1:
// Scala program of compareTo()// method // Creating objectobject GfG{ // Main method def main(args:Array[String]) { // Creating a String val m1 = "Nidhi" // Applying compareTo() method val result = m1.compareTo("Nidhi") // Displays output println(result) }} |
Output:
0
It returns zero as both the strings are same.
Example #2:
// Scala program of compareTo()// method // Creating objectobject GfG{ // Main method def main(args:Array[String]) { // Creating a String val m1 = "Nidhi" // Applying compareTo() method val result = m1.compareTo("Nidh") // Displays output println(result) }} |
Output:
1
It returns a positive number as S1 is greater than S2 here.
Example #3:
// Scala program of compareTo()// method // Creating objectobject GfG{ // Main method def main(args:Array[String]) { // Creating a String val m1 = "Nidhi" // Applying compareTo() method val result = m1.compareTo("nidh") // Displays output println(result) }} |
Output:
-32
It returns a negative number as S1 is less than S2 here.
