How can one prove that array is not null but empty ?
Answer : Check its null value first then check length of the array. Please see example below:
public class ArrayNullCheck { public static void main(String[] args) { String arrayCheck[] = new String[2]; arrayCheck[0] = "Java"; arrayCheck[1] = "Honk"; if (null != arrayCheck && arrayCheck.length != 0) { System.out.println(arrayCheck.length); } } }
