How to remove an element from a list in Java?

To remove a specific element from a List in Java, you can use the `remove()` method. Here are a few ways to delete elements from a List.

Remove elements by their values.

List<String> list = new ArrayList<>();
list.add("Apple");
list.add("Banana");
list.add("Orange");
list.remove("Banana"); // 通过元素值删除
System.out.println(list); // 输出: [Apple, Orange]

Remove elements by their index position.

List<String> list = new ArrayList<>();
list.add("Apple");
list.add("Banana");
list.add("Orange");
list.remove(1); // 通过索引位置删除 (索引从0开始)
System.out.println(list); // 输出: [Apple, Orange]

3. Removing elements using iterators:

List<String> list = new ArrayList<>();
list.add("Apple");
list.add("Banana");
list.add("Orange");
Iterator<String> iterator = list.iterator();
while (iterator.hasNext()) {
    String element = iterator.next();
    if (element.equals("Banana")) {
        iterator.remove(); // 使用迭代器删除
    }
}
System.out.println(list); // 输出: [Apple, Orange]

You can use any method to remove a specific element from the list. Just choose the method that suits your needs.
