{"orderID"- 1, "content"- {"productID" - 2, "Name"- "Pen", "Count"- 5}} {"orderID": 1, "content": {"productID": 2, "Name": "Pen", "Count": 5}} {"orderID": 1, "content": {"productID": 2, "Name": "Pen", "Count": "5"}}

The first JSON object has a syntax error with the key-value pair for "content" as it uses a hyphen instead of a colon. The correct format should use a colon to separate the key and value.

The second JSON object is correctly formatted with the key-value pairs separated by colons.

The third JSON object has a syntax error with the value for "Count" as it is enclosed in quotes, making it a string instead of a number. The value should be without quotes to represent a number.
