[java] Converting List<String> to String[] in Java

How do I convert a list of String into an array? The following code returns an error.

public static void main(String[] args) {
    List<String> strlist = new ArrayList<String>();
    strlist.add("sdfs1");
    strlist.add("sdfs2");
    String[] strarray = (String[]) strlist.toArray();       
    System.out.println(strarray);
}

Error:

Exception in thread "main" java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to [Ljava.lang.String;
    at test.main(test.java:10)

hope this can help someone out there:

List list = ..;

String [] stringArray = list.toArray(new String[list.size()]);

great answer from here: https://stackoverflow.com/a/4042464/1547266

I've designed and implemented Dollar for this kind of tasks:

String[] strarray= $(strlist).toArray();

List.toArray() necessarily returns an array of Object. To get an array of String, you need to use the casting syntax:

String[] strarray = strlist.toArray(new String[0]);

See the javadoc for java.util.List for more.

public static void main(String[] args) {
    List<String> strlist = new ArrayList<String>();
    strlist.add("sdfs1");
    strlist.add("sdfs2");

    String[] strarray = new String[strlist.size()]
    strlist.toArray(strarray );

    System.out.println(strarray);


}

String[] strarray = strlist.toArray(new String[0]);

if u want List convert to string use StringUtils.join(slist, '\n');
