Example of JSONArray mutual conversion code of List and fastjson in Java

List and JSONArray convert each other

List to JSONArray

After copying, run it directly, the code is as follows:

        ("List to JSONArray");
		List&lt;String&gt; list = new ArrayList&lt;&gt;();
		("a");
		("b");
		("c");
		("\nOriginal list: " + list);

		// Method 1: Use JSONArray to construct the method		JSONArray jsonArray1 = new JSONArray((list));
		("Method 1:" + jsonArray1);

		// Method 2: Convert List to JSON string, both are OK		JSONArray jsonArray2 = ((list));
		//JSONArray jsonArray2 = ((list));
		("Method 2:" + jsonArray2);

		// Method 3: Convert List to JSON string and then force it to		JSONArray jsonArray3 = (JSONArray) (list);
		("Method 3:" + jsonArray3);

JSONArray to List

        ("JSONArray to List");
		JSONArray array = new JSONArray();
		("a");
		("b");
		("c");
		("\nOriginal JSONArray: " + array);

		// Both are available		List&lt;String&gt; strList = ((), );
		// List&lt;String&gt; strList = ((), );
		(": " + strList);
