# Scala Programming: Create a new string from a given string swapping the last two characters of the given string

## Scala Programming String Exercise-20 with Solution

Write a Scala program to create a new string from a given string swapping the last two characters of the given string. The length of the given string must be two or more.

Sample Solution:

Scala Code:

``````object Scala_String {
def lastTwo(str1: String): String = {
if (str1.length() < 2) return str1;
return str1.substring(0, str1.length - 2) + str1.charAt(str1.length - 1) + str1
.charAt(str1.length - 2);
}
def main(args: Array[String]): Unit = {
var str1 = "String";
println("The given strings is: " + str1);
println("The string after swap last two characters are: " + lastTwo(str1));
str1 = "Scala";
println("The given strings is: " + str1);
println("The string after swap last two characters are: " + lastTwo(str1));
}
}
``````

Sample Output:

```The given strings is: String
The string after swap last two characters are: Strign
The given strings is: Scala
The string after swap last two characters are: Scaal
```
