Hello
I've been working on a program and I've encountered a little problem
Here is the simplest form of my problem

public static void main(String[] args) {		int[] a = new int[]{1,2,3};
		trial3(a);
	}
	
	private static void trial3(int[] i) {
		int[] b = i;
		b[1] = 0;
		System.out.println(Arrays.toString(b)+ Arrays.toString(i));
	}

I expect the result would be [1, 0, 3][1, 2, 3] but instead the real result is
[1, 0, 3][1, 0, 3]
I don't really know why this happen could someone please explain it to me and
Tell me a simple way to get the expected result.
