Java/Data Type/String sort

Sort array values in case insensitive order

 
 
import java.util.Arrays;
public class Main {
  public static void main(String[] args) {
    String[] teams = new String[5];
    teams[0] = "M";
    teams[1] = "c";
    teams[2] = "A";
    teams[3] = "l";
    teams[4] = "E";
    Arrays.sort(teams);
    System.out.println(Arrays.toString(teams));
    Arrays.sort(teams, String.CASE_INSENSITIVE_ORDER);
    System.out.println(Arrays.toString(teams));
  }
}

Sorting a string List

 
import java.util.Arrays;
import java.util.Collections;
import java.util.List;
public class Main {
  public static void main(String[] argv) throws Exception {
    String[] strArray = new String[] { "z", "a", "A" };
    List list = Arrays.asList(strArray);
    Collections.sort(list);
    Collections.sort(list, String.CASE_INSENSITIVE_ORDER);
    Collections.sort(list, Collections.reverseOrder());
    Collections.sort(list, String.CASE_INSENSITIVE_ORDER);
    Collections.reverse(list);
  }
}

String.CASE_INSENSITIVE_ORDER

 
import java.util.Arrays;
import java.util.Collections;
import java.util.List;
public class Main {
  public static void main(String[] argv) throws Exception {
    String[] strArray = new String[] { "z", "a", "A" };
    List list = Arrays.asList(strArray);
    Collections.sort(list);
    Collections.sort(list, String.CASE_INSENSITIVE_ORDER);
    Collections.sort(list, Collections.reverseOrder());
    Collections.sort(list, String.CASE_INSENSITIVE_ORDER);
    Collections.reverse(list);
  }
}
