将JSON对象存储为字符串并在java中打印每个值

Question

I have a JSON object {"name":["123-abc","234-bca","567-yuio"]} with unknown length. I need to store it as a string and split the commas and iterate to print only the value ie 123-abc should be printed first then 234-bca etc.. -> Input: {"name":["123-abc","234-bca","567-yuio"]} -> Output: 123-abc 234-bca 567-yuio

Please help me out as I'm new to coding. Thank You

Answer 1

You can try this:

JSONObject json = (JSONObject) object;
String input = json.get("name");
//String input = "\"123-abc\",\"234-bca\",\"567-yuio\"";
String[] strArray = input.split(",");
for (String string : strArray)
    System.out.println(string.replace("\"", ""));

Here object is where you stored your JSON object.

At first, you have to split the string at the commas and you have to iterate over the split list, using eg a for-loop:

for (String val : input.substring(1, input.length() - 1).split(",")) {
    System.out.println(val.replace("\"", ""));
}

You shouldn't need to store it as a string, you can actually just pull out that array from the JSON object and iterate over it.

JSON obj = new JSONObject(); //Get/store your data however you'd like. I will call it obj
String[] name  = obj.get( "name" );
for (int i = 0; i < name.length; i++) { //Loop through your array and output each part
    System.out.println( name[ i ] );
}

If you need to convert the obj to a string use can use the .toString() function. But the above should be the easiest way to output that data.
