What are the methods to convert array to List in Java?

There are three methods for converting arrays to List in Java: "asList(static method", "for loop traversal", and "Java 8's Stream API": 1. Use the asList() static method of the Arrays class , returns a fixed-length List, which cannot be added or deleted; 2. Use a for loop to traverse the array and add it to the List one by one; 3. Use the Stream API introduced in Java 8.

In Java, you can use the following methods to convert an array to a List:

1. Use the asList() static method of the Arrays class

String[] array = {"apple", "banana", "orange"};
List<string> list = Arrays.asList(array);</string>

This method is the most commonly used one and can quickly convert an array into a List. It should be noted that the asList() method returns a fixed-length List and cannot be added or deleted. .If you need to modify the List, you can do so by creating a new ArrayList object:

String[] array = {"apple", "banana", "orange"};
List<string> list = new ArrayList(Arrays.asList(array));</string>

2. Use a for loop to traverse the array and add it to the List one by one

String[] array = {"apple", "banana", "orange"};
List<string> list = new ArrayList();
for (String item : array) {
    list.add(item);
}</string>

This method is more cumbersome, but it can flexibly control the order and conditions of addition.

3. Using the Stream API of Java 8

String[] array = {"apple", "banana", "orange"};
List<string> list = Arrays.stream(array).collect(Collectors.toList());</string>

This method uses the Stream API introduced by Java 8 The Stream API can easily complete the conversion from an array to a List, but it should be noted that the array must be converted to a Stream object before the Collectors.toList() method can be used.
