The code is as follows
Package testcourse;

public class Test {
    public static void Main (string[] args) {
        String[] k = new string[5];
        K[0] = "a";
        K[1] = "B";
        for (int i = 0; i<k.length; i++) {
                System.out.print (k[i]+ ",");
        }
    }
}
Operation result is A,b,null,null,null
Is there any way to loop through null and not output?
