我们正在读取文件，更改内容并写回同一位置。
如何在java/only特定属性中对json数组应用缩进？
源代码：

import com.google.gson.JsonElement;
import com.google.gson.internal.Streams;
import com.google.gson.stream.JsonReader;
import com.google.gson.stream.JsonWriter;

String file="D:\\Documents\\read.json";     
JsonElement root = Streams.parse(new JsonReader(new FileReader(file)));
// changing the json values here
try (Writer writer = new FileWriter(file)) {
    JsonWriter jsonWriter = new JsonWriter(writer);
    jsonWriter.setIndent("\t");
    Streams.write(root, jsonWriter);
    jsonWriter.flush();
}  catch (IOException ioe) {
    ioe.printStackTrace();
}

我们拥有：

{
  "array": ["element 1","element 2","element 3" ],
  "object": {
    "property1": "value1",
    "property2":"value2"
  }
}

生成的代码：

{
    "array": [
        "element 1",
        "element 2",
        "element 3"
    ],
    "object": {
        "property1": "value1",
        "property2": "value2"
    }
}

我们需要什么

{
  "array": ["element 1","element 2","element 3" ],
  "object": {
    "property1": "value1",
    "property2":"value2"
  }
}
