No, array size cannot be negative. If we specify array size as negative, there will be no compile time error. But there will be run time NegativeArraySizeException.
Example
class Main { public static void main(String[] args) { int[] testArray = new int[4]; for (int i = 0; i < testArray.length; ++i) { System.out.println(testArray[i]); } } } |
Output
0 0 0 0 |
We will get run time error (NegativeArraySizeException), if we specify negative array size. Example
class Main { public static void main(String[] args) { int[] testArray = new int[-4]; for (int i = 0; i < testArray.length; ++i) { System.out.println(testArray[i]); } } } |
Output
Exception in thread "main" java.lang.NegativeArraySizeException at Main.main(Main.java:4) |
