获取用户对HashMap的输入作为键，并在Java语言中打印其各自的值

import java.util.HashMap;
import java.util.Scanner;

HashMap<String, String> hashMap = new HashMap<>();

Scanner scanner = new Scanner(System.in);
System.out.print("请输入键：");
String key = scanner.nextLine();
System.out.print("请输入值：");
String value = scanner.nextLine();

hashMap.put(key, value);

for (String k : hashMap.keySet()) {
    System.out.println("键：" + k + "，值：" + hashMap.get(k));
}

import java.util.HashMap;
import java.util.Scanner;

public class HashMapExample {
    public static void main(String[] args) {
        HashMap<String, String> hashMap = new HashMap<>();

        Scanner scanner = new Scanner(System.in);
        System.out.print("请输入键：");
        String key = scanner.nextLine();
        System.out.print("请输入值：");
        String value = scanner.nextLine();

        hashMap.put(key, value);

        for (String k : hashMap.keySet()) {
            System.out.println("键：" + k + "，值：" + hashMap.get(k));
        }
    }
}
