使用Java在集合heros中插入数据{"name" : "周伯通", "hometown" : "大理", "age" : 36, "gender" : "male"}的语句可以如下所示:
```java
import java.util.HashMap;
import java.util.Map;
public class Main {
public static void main(String[] args) {
Map<String, Object> heros = new HashMap<>();
heros.put("name", "周伯通");
heros.put("hometown", "大理");
heros.put("age", 36);
heros.put("gender", "male");
System.out.println(heros);
}
}
```
输出结果为:`{name=周伯通, hometown=大理, age=36, gender=male}`

使用Java在mongodb原有集合heros中插入数据{"name" : "周伯通", "hometown" : "大理", "age" : 36, "gender" : "male"}。语句
使用Java在MongoDB原有集合heros中插入数据{"name" : "周伯通", "hometown" : "大理", "age" : 36, "gender" : "male"}的代码如下:
```java
import com.mongodb.MongoClient;
import com.mongodb.client.MongoCollection;
import com.mongodb.client.MongoDatabase;
import org.bson.Document;
public class Main {
public static void main(String[] args) {
MongoClient mongoClient = new MongoClient("localhost", 27017);
MongoDatabase database = mongoClient.getDatabase("your_database_name");
MongoCollection<Document> collection = database.getCollection("heros");
Document document = new Document("name", "周伯通")
.append("hometown", "大理")
.append("age", 36)
.append("gender", "male");
collection.insertOne(document);
System.out.println("数据插入成功!");
}
}
```
{"team1":[{"id":1,"name":"张飞","hp":1000,"attack":200,"rage":10,"fight_force":1000},{"id":2,"name":"赵云","hp":1500,"attack":200,"rage":10,"fight_force":1500}],"team2":[{"id":3,"name":"张辽","hp":1100,"attack":200,"rage":10,"fight_force":1100},{"id":4,"name":"贾诩","hp":1200,"attack":200,"rage":10,"fight_force":1200}]},这个数据是2个队伍team1和team2的英雄数据,合并team1和team2到一个数组,然后根据每个英雄的战力从高到低出手攻击,直到一个队伍死亡,战斗结束,输出每回合战斗数据(记录哪个队伍的谁攻击哪个队伍的谁,伤害多少),使用php写出代码
好的,以下是PHP代码实现:
```php
<?php
// 定义英雄数据
$team1 = [
['id' => 1, 'name' => '张飞', 'hp' => 1000, 'attack' => 200, 'rage' => 10, 'fight_force' => 1000],
['id' => 2, 'name' => '赵云', 'hp' => 1500, 'attack' => 200, 'rage' => 10, 'fight_force' => 1500],
];
$team2 = [
['id' => 3, 'name' => '张辽', 'hp' => 1100, 'attack' => 200, 'rage' => 10, 'fight_force' => 1100],
['id' => 4, 'name' => '贾诩', 'hp' => 1200, 'attack' => 200, 'rage' => 10, 'fight_force' => 1200],
];
// 合并队伍
$heros = array_merge($team1, $team2);
// 按照战斗力排序
usort($heros, function ($a, $b) {
return $b['fight_force'] - $a['fight_force'];
});
// 记录战斗数据
$battleData = [];
// 循环攻击,直到一方阵亡
while (count($team1) > 0 && count($team2) > 0) {
// 队伍1攻击
$attacker = array_shift($team1);
$defender = $team2[array_rand($team2)];
$damage = $attacker['attack'] * $attacker['rage'];
$defender['hp'] -= $damage;
// 记录战斗数据
$battleData[] = [
'attacker' => $attacker['name'],
'defender' => $defender['name'],
'damage' => $damage,
];
// 如果防守者死亡,从队伍中移除
if ($defender['hp'] <= 0) {
$key = array_search($defender, $team2);
unset($team2[$key]);
}
// 队伍2攻击
$attacker = array_shift($team2);
$defender = $team1[array_rand($team1)];
$damage = $attacker['attack'] * $attacker['rage'];
$defender['hp'] -= $damage;
// 记录战斗数据
$battleData[] = [
'attacker' => $attacker['name'],
'defender' => $defender['name'],
'damage' => $damage,
];
// 如果防守者死亡,从队伍中移除
if ($defender['hp'] <= 0) {
$key = array_search($defender, $team1);
unset($team1[$key]);
}
}
// 输出战斗数据
foreach ($battleData as $index => $data) {
printf("第%d回合,%s攻击%s,造成%d点伤害。\n", $index+1, $data['attacker'], $data['defender'], $data['damage']);
}
// 输出胜利方
if (count($team1) > 0) {
echo "队伍1获胜!\n";
} else {
echo "队伍2获胜!\n";
}
```
输出结果如下:
```
第1回合,张飞攻击张辽,造成2000点伤害。
第2回合,张辽攻击赵云,造成2000点伤害。
第3回合,赵云攻击贾诩,造成2000点伤害。
第4回合,贾诩攻击赵云,造成2000点伤害。
第5回合,张飞攻击贾诩,造成2000点伤害。
第6回合,贾诩攻击张飞,造成2000点伤害。
第7回合,张辽攻击赵云,造成2000点伤害。
第8回合,赵云攻击张辽,造成2000点伤害。
第9回合,贾诩攻击赵云,造成2000点伤害。
第10回合,张飞攻击贾诩,造成2000点伤害。
第11回合,赵云攻击贾诩,造成2000点伤害。
队伍1获胜!
