Java Program to sort a List in case insensitive order
Let’s say your list is having the following elements −
P, W, g, K, H, t, E
Therefore, case sensitive order means, capital and small letters will be considered irrespective of case. The output would be −
E, g, H, K, P, t, W
The following is our array −
String[] arr = new String[] { "P", "W", "g", "K", "H", "t", "E" };Convert the above array to a List −
List<String>list = Arrays.asList(arr);
Now sort the above list in case insensitive order −
Collections.sort(list, String.CASE_INSENSITIVE_ORDER);
Example
import java.util.Arrays;
import java.util.Collections;
import java.util.List;
public class Demo {
public static void main(String[] argv) throws Exception {
String[] arr = new String[] { "P", "W", "g", "K", "H", "t", "E" };
List<String>list = Arrays.asList(arr);
System.out.println("List = "+list);
Collections.sort(list);
System.out.println("Case Sensitive Sort = "+list);
Collections.sort(list, String.CASE_INSENSITIVE_ORDER);
System.out.println("Case Insensitive Sort = "+list);
}
}Output
List = [P, W, g, K, H, t, E] Case Sensitive Sort = [E, H, K, P, W, g, t] Case Insensitive Sort = [E, g, H, K, P, t, W]
