从字符串数组生成map

import java.util.HashMap;
import java.util.Map;

public class StringArrayToMap {
    public static void main(String[] args) {
        String[] stringArray = {"key1", "value1", "key2", "value2", "key3", "value3"};

        Map<String, String> map = new HashMap<>();

        for (int i = 0; i < stringArray.length; i += 2) {
            String key = stringArray[i];
            String value = (i + 1 < stringArray.length) ? stringArray[i + 1] : null;
            map.put(key, value);
        }

        System.out.println(map);
    }
}
