java create list with one element

To create a list with a single element in Java, you can use the Collections.singletonList method from the java.util package.

Here is an example of how to create a list with a single element:

import java.util.List;
import java.util.Collections;

public class Main {
    public static void main(String[] args) {
        List<String> list = Collections.singletonList("apple");
        System.out.println(list);  // prints [apple]
    }
}

This creates a new list with the single element "apple".

You can also create a list with a single element using the Arrays.asList method from the java.util package. For example:

import java.util.List;
import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        List<String> list = Arrays.asList("apple");
        System.out.println(list);  // prints [apple]
    }
}
