A quirk of changing sign?

This sign change wil work!

	public static  void main(String[] args) {
		int lowestInt = -2147483647;
		System.out.println("lowestInt "+ lowestInt);
		int oppositeOfLowestInt = lowestInt/-1;
		System.out.println("oppositeOfLowestInt  "+ oppositeOfLowestInt);
	}

However, change the value of our lowestInt by one and you will get a suprising result. If you run the function below, you will find the the oppositeOfLowestInt has not changed and evaluates to = -2147483648.

	public static  void main(String[] args) {
		int lowestInt = -2147483648;
		System.out.println("lowestInt "+ lowestInt);
		int oppositeOfLowestInt = lowestInt/-1;
		System.out.println("oppositeOfLowestInt  "+ oppositeOfLowestInt);
	}
