import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
public class StringSortExample {
public static void main(String[] args) {
List<String> strings = new ArrayList<>();
strings.add("banana");
strings.add("apple");
strings.add("cherry");
// Sorting the list of strings using a lambda expression
Collections.sort(strings, (str1, str2) -> str1.compareTo(str2));
// Printing the sorted list
for (String s : strings) {
System.out.println(s);
}
// Alternative method using the sort method from List
List<String> anotherList = new ArrayList<>();
anotherList.add("orange");
anotherList.add("grape");
anotherList.add("kiwi");
anotherList.sort((str1, str2) -> str1.compareTo(str2));
System.out.println("\nSorted another list:");
for (String s : anotherList) {
System.out.println(s);
}
}
