java: List of String Arrays and remove

Question

In a test like this:

    @Test
    public void test() {
        List l = new LinkedList();
        l.add(new String [] {\"tes         


        

Answer 1

The List method are often based on the Object method equals(Object o) which compare the object's reference by default. You may store the tab if you want remove it later, or create your own class and override equals(Object o) ;)

    @Test
    public void test() {
        List l = new LinkedList();
        l.add(new String [] {"test", "123"});
        String[] tab = new String [] {"test", "456"};
        l.add(tab);
        l.add(new String [] {"test", "789"});

        assertEquals(3, l.size());

        l.remove(tab);

        assertEquals(2, l.size());
    }
