Can I define an array with negative size?

No, you can’t define an array with negative size. As per Java documentation, array has public final field length, which contains the number of components of the array. length may be positive or zero.

App.java

package com.sample.app;

public class App {
	public static void main(String args[]) {
		int[] arr1 = new int[-1];

		System.out.println("arr1 length : " + arr1.length);

	}
}

Run App.java, you will get ‘NegativeArraySizeException’.

Exception in thread "main" java.lang.NegativeArraySizeException

         at com.sample.app.App.main(App.java:5)
