How to Shorten a Name in java

How to Shorten a Name in java?

Without going in depth i would like to show you the Code...



/*----Program begin---*/
import java.util.Locale;
public class ShortName{
    public static void main(String[] args) {
        String name = "Aamir khan";
        String[] shortName = name.split("\\s");
        int len = shortName.length;
        switch(len){
            case 3: System.out.printf("%1.1s. %1.1s. %s", shortName[0].toUpperCase(Locale.ROOT),
                         shortName[1].toUpperCase(Locale.ROOT), shortName[2]);
                break;
            case 2: System.out.printf("%1.1s. %s", shortName[0].toUpperCase(Locale.ROOT),
                             shortName[1]);
                break;
            case 1: System.out.printf("%s", shortName[0]);
                break;
            default: System.out.println("Errorr !!! occured");
        }
        System.out.println("");
    }

}
/*---Program End---*/


updated one:

/*---Program Begin ---*/
    public static void main(String[] args) {
       
        String name = "Avul Pakir Jainulabdeen Abdul kalam";
        String[] splitedName = name.split("\\s");
        String shortName = "";
       
        int len = (splitedName.length - 1);

        for (int i = 0; i < len; i++)
            shortName = shortName.concat(splitedName[i].charAt(0) + ". ");
       
        shortName = shortName.concat(splitedName[len]);
        System.out.println(shortName.toUpperCase());
    }
/*---Program End---*/
