如何将字符串(表示键-值对)转换为Map

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

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

        // Step 1: Split the string by comma
        String[] keyValuePairs = input.split(",");

        // Step 3: Create an empty map
        Map<String, String> map = new HashMap<>();

        // Step 4: Iterate over each key-value pair
        for (String pair : keyValuePairs) {
            // Step 2: Split the pair by equal sign
            String[] entry = pair.split("=");

            // Step 4: Add the key-value pair to the map
            if (entry.length == 2) {
                String key = entry[0];
                String value = entry[1];
                map.put(key, value);
            }
        }

        // Print the resulting map
        for (Map.Entry<String, String> entry : map.entrySet()) {
            System.out.println(entry.getKey() + " -> " + entry.getValue());
        }
    }
}
