如何在Java中创建JSON数组并将其写入文件？
Java提供了javax.json.Json包，其中包含读取JSON数组的类：
示例
import java.io.FileOutputStream;
import javax.json.Json;
import javax.json.JsonArray;
import javax.json.JsonWriter;
public class JSONArrayToFile {
public static void main(String args[]) throws Exception {
JsonArray value = Json.createArrayBuilder()
.add(Json.createObjectBuilder()
.add("id", "1001")
.add("Technology", "JavaFX"))
.add(Json.createObjectBuilder()
.add("id", "1002")
.add("Technology", "OpenCV"))
.build();
System.out.println(value);
JsonWriter writer = Json.createWriter(new FileOutputStream("sampleData"));
writer.writeArray(value);
writer.close();
}
}输出结果
["JavaFX","HBase","JOGL","WebGL"] After deleting ::["JavaFX","HBase","JOGL"]
