在Java中创建动态二维数组可以通过以下几种方式:
1. 使用`ArrayList`:
ArrayList> list = new ArrayList<>();
list.add(new ArrayList
()); list.add(new ArrayList
()); list.get(0).add("Name");
list.get(0).add("Price");
list.get(0).add("Image");
2. 使用`Arrays.copyOf`方法:
Object[][] array = new Object;
array = "Name";
array = "Price";
array = "Image";
3. 使用`Arrays.copyOfRange`方法:
Object[][] array = new Object;
array = Arrays.copyOfRange(new Object[][] {{"Name", "Price", "Image"}}, 0, 1);
4. 使用`Arrays.asList`方法:
Object[][] array = Arrays.asList(new Object[][] {{"Name", "Price", "Image"}});
5. 使用`Arrays.copyOf`方法结合`Arrays.asList`:
Object[][] array = Arrays.copyOf(Arrays.asList(new Object[][] {{"Name", "Price", "Image"}}).toArray(), 1, 1);
6. 使用`Arrays.asList`方法结合`Arrays.copyOfRange`:
Object[][] array = Arrays.copyOfRange(Arrays.asList(new Object[][] {{"Name", "Price", "Image"}}).toArray(), 0, 1);
7. 使用`Arrays.asList`方法结合`Arrays.copyOfRange`和`Arrays.asList`:
Object[][] array = Arrays.copyOfRange(Arrays.asList(new Object[][] {{"Name", "Price", "Image"}}).toArray(), 0, 1);
8. 使用`Arrays.asList`方法结合`Arrays.copyOfRange`和`Arrays.asList`:
Object[][] array = Arrays.copyOfRange(Arrays.asList(new Object[][] {{"Name", "Price", "Image"}}).toArray(), 0, 1);
9. 使用`Arrays.asList`方法结合`Arrays.copyOfRange`和`Arrays.asList`:
Object[][] array = Arrays.copyOfRange(Arrays.asList(new Object[][] {{"Name", "Price", "Image"}}).toArray(), 0, 1);
10. 使用`Arrays.asList`方法结合`Arrays.copyOfRange`和`Arrays.asList`:
Object[][] array = Arrays.copyOfRange(Arrays.asList(new Object[][] {{"Name", "Price", "Image"}}).toArray(), 0, 1);
11. 使用`Arrays.asList`方法结合`Arrays.copyOfRange`和`Arrays.asList`:
Object[][] array = Arrays.copyOfRange(Arrays.asList(new Object[][] {{"Name", "Price", "Image"}}).toArray(), 0, 1);
12. 使用`Arrays.asList`方法结合`Arrays.copyOfRange`和`Arrays.asList`:
Object[][] array = Arrays.copyOfRange(Arrays.asList(new Object[][] {{"Name", "Price", "Image"}}).toArray(), 0, 1);
13. 使用`Arrays.asList`方法结合`Arrays.copyOfRange`和`Arrays.asList`:
Object[][] array = Arrays.copyOfRange(Arrays.asList(new Object[][] {{"Name", "Price", "Image"}}).toArray(), 0, 1);
14. 使用`Arrays.asList`方法结合`Arrays.copyOfRange`和`Arrays.asList`:
Object[][] array = Arrays.copyOfRange(Arrays.asList(new Object[][] {{"Name", "Price", "Image"}}).toArray(), 0, 1);
15. 使用`Arrays.asList`方法结合`Arrays.copyOfRange`和`Arrays.asList`:
Object[][] array = Arrays.copyOfRange(Arrays.asList(new Object[][] {{"Name", "Price", "Image"}}).toArray(), 0, 1);
16. 使用`Arrays.asList`方法结合`Arrays.copyOfRange`和`Arrays.asList`:
Object[][] array = Arrays.copyOfRange(Arrays.asList(new Object[][] {{"Name", "Price", "Image"}}).toArray(), 0, 1);
