onnam mehema loop ekakin add karannath puluwan.

public static void main(String[] args) {
        String[] array1 = new String[]{"A", "B", "C"};
        String[] array2 = new String[array1.length];

        for (int i=0; i< array1.length; i++) {
            array2[i] = array1[i];
        }

        List<String[]> list = new ArrayList<>();
        List<String[]> duplicateList = new ArrayList<>();

        list.add(array1);
        duplicateList.add(array2);

        ContentTest contentTest = new ContentTest();
        contentTest.setContent(duplicateList);
        contentTest.print();

        System.out.println("Original List");
        for (String values[] : list) {
            System.out.println(Arrays.asList(values));
        }

ok.. machan me krame wada... 14+

replay එකට තෑන්ක්ස්. ඒත් ContentTest class එක වෙනස් කරන්න බෑ. එහෙම කලොත් ඒක වෙන ප්‍රශ්න ගොඩක් හදනව. මට මේන් එකේ පාස් වෙන තැනින් විතරයි වෙනසක් කරන්න පුලුවන්.

Mama dunne explanation ekak. Okata karanna wenne ekko new array ekak hadana eka nathnam clone ekak gahana eka. Just a shallow copy won't work. Give me a second i will get back to you with an example

Ah mey tiyenney. This works
