在方法中被重写时，数组参数不会在其外部更改

public class ArrayExample {
    public static void main(String[] args) {
        int[] array = {1, 2, 3};
        System.out.println("Before method call: " + Arrays.toString(array));
        modifyArray(array);
        System.out.println("After method call: " + Arrays.toString(array));
    }
    
    public static void modifyArray(int[] arr) {
        arr[0] = 10;
        arr[1] = 20;
        arr[2] = 30;
        System.out.println("Inside method: " + Arrays.toString(arr));
    }
}

Before method call: [1, 2, 3]
Inside method: [10, 20, 30]
After method call: [10, 20, 30]
