这个数据不能正确保存到JSON文件中。因为它是多个JSON对象的集合,而JSON文件只能包含一个JSON对象或一个JSON数组。如果要将这些JSON对象保存到文件中,可以将它们组合成一个JSON数组,然后将数组写入文件中。
以下是一个示例代码,将这些JSON对象组合成一个JSON数组,并将它们写入名为"output.json"的文件中:
```java
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
public class WriteJsonArrayToFileExample {
public static void main(String[] args) {
try {
FileWriter writer = new FileWriter("output.json");
BufferedWriter buffer = new BufferedWriter(writer);
String jsonArray = "[" +
"{\"id\":\"1092000\",\"type\":\"reference\",\"title\":\"An Introduction to the History of Mathematics \",\"url\":\"https://archive.org/details/introductiontohi0000eves \"}," +
"{\"id\":\"1092000\",\"type\":\"reference\",\"title\":\"数学与算术、算学\",\"url\":\"http://hk.chiculture.net/0803/html/c01/0803c01.html\"}," +
"{\"id\":\"1092000\",\"type\":\"reference\",\"title\":\"书评:《毛起来说三角》\",\"url\":\"http://math.ntnu.edu.tw/~horng/letter/vol4no1b.htm\"}," +
"{\"id\":\"1092000\",\"type\":\"reference\",\"title\":\"数学的三个发展时期——初等数学时期\",\"url\":\"http://www.pep.com.cn/czsx/xszx/czsxkwyd/czsxkwydsxgs/201008/t20100824_718183.htm\"}" +
"]";
buffer.write(jsonArray);
buffer.close();
System.out.println("Data has been written to the file.");
} catch (IOException e) {
System.out.println("An error occurred.");
e.printStackTrace();
}
}
}
```
此代码将这些JSON对象组合成一个JSON数组,并将它们写入名为"output.json"的文件中。请注意,我们在JSON对象之间添加了逗号",",并将它们组合在一个方括号"[]"中,以表示它们是一个JSON数组。
