java怎么将数组里的数据存入数据库

```java

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.PreparedStatement;

import java.sql.SQLException;

public class ArrayToDatabase {

public static void main(String[] args) {

String url = "jdbc:mysql://localhost:3306/mydatabase";

String username = "username";

String password = "password";

Connection conn = null;

try {

conn = DriverManager.getConnection(url, username, password);

int[] data = https://www.yisu.com/ask/{1, 2, 3, 4, 5};

String query = "INSERT INTO mytable (column_name) VALUES (?)";

PreparedStatement preparedStatement = conn.prepareStatement(query);

for (int i = 0; i < data.length; i++) {

preparedStatement.setInt(1, data[i]);

preparedStatement.executeUpdate();

}

System.out.println("Data inserted successfully");

} catch (SQLException e) {

e.printStackTrace();

} finally {

if (conn != null) {

try {

conn.close();

} catch (SQLException e) {

e.printStackTrace();

}

}

}

}

}

```

在上面的示例代码中，首先建立了与数据库的连接，接着定义了一个整型数组`data`，然后通过PreparedStatement将数组中的数据逐个插入到数据库表中。最后关闭数据库连接。请根据实际情况修改数据库连接信息、数据表名称和字段名。
