printArray error

[ice_breaker]

Below is my code and I expect the result is
array1 is <2, 3, 5, 7, 11, 13, 17, 19>
array1 is <0, 3, 2, 7, 4, 13, 6, 19>

but the result shows like:

array1 is: <>
array1 is <>

Please advise. Thanks

    
        public static void main(String[] args) {
        // TODO code application logic here
        int[] array1 = {2, 3, 5, 7, 11, 13, 17, 19};
        int[] array2;
        System.out.print("array1 is: ");
        printArray(array1);
        System.out.println();

        array2 = array1;
        array2[0] = 2;
        array2[1] = 3;
        array2[2] = 2;
        array2[3] = 7;
        array2[4] = 4;
        array2[5] = 13;
        array2[6] = 6;
        array2[7] = 19;

        System.out.print("array1 is ");
        printArray(array1);
        System.out.println();
    }

    public static void printArray(int[] array) {
        System.out.print('<');
        for (int i = 0; i < array.length; i++) {
        // print an element

        //Do the coding here

        // print a comma delimiter if not the last element

        //Do the coding here
        }
        System.out.print('>');
    }
}

I don't know where that zero comes from in your second print; you are hiding something from us; in your actual code you showed us you're not printing anything except for those angular brackets.

kind regards,

Jos

No, I don't hide anything. I don't know why it doesn't show up like my expectation and thus it's great that you can fix and adjust my program to produce as my expected result, so I can learn from it. Thanks

I just solved my error. Below is the complete code:

public static void main(String[] args) {
        // TODO code application logic here
        int[] array1 = {2, 3, 5, 7, 11, 13, 17, 19};
        int[] array2;
        System.out.print("array1 is: ");
        printArray(array1);
        System.out.println();

        array2 = array1;
        array2[0] = 2;
        array2[1] = 3;
        array2[2] = 2;
        array2[3] = 7;
        array2[4] = 4;
        array2[5] = 13;
        array2[6] = 6;
        array2[7] = 19;

        System.out.print("array1 is ");
        printArray(array1);
        System.out.println();
    }

    public static void printArray(int[] array) {
        System.out.print('<');
        for (int i = 0; i < array.length; i++) {
            System.out.print(array[i]);
            if(i <(array.length -1))
            {
                System.out.print(", ");
            }

        }
        System.out.print('>');
    }
}
