Answer 1

You need to add your POJO structure to the question to make it clear. But maybe you need to remove the " inside your first json array.

So it will look like this

[
   [
      {
         "IdProduit":1,
         "NumeroSerie":"1234579657",
         "NomProduit":"Puce BigKing",
         "Prix":200.0,
         "Quantite":500,
         "IdModel":1,
         "IdModelNavigation":{
            "IdModel":1,
            "NomModel":"Puces",
            "Produit":[

            ],
            "StockModel":[

            ]
         }
      },
      {
         "IdProduit":2,
         "NumeroSerie":"12345687",
         "NomProduit":"Puce La Win",
         "Prix":2000.0,
         "Quantite":60,
         "IdModel":1,
         "IdModelNavigation":{
            "IdModel":1,
            "NomModel":"Puces",
            "Produit":[

            ],
            "StockModel":[

            ]
         }
      },
      {
         "IdProduit":3,
         "NumeroSerie":"124576328",
         "NomProduit":"Carte De Recharge 200DA",
         "Prix":200.0,
         "Quantite":300,
         "IdModel":2,
         "IdModelNavigation":{
            "IdModel":2,
            "NomModel":"Carte De Recharge",
            "Produit":[

            ],
            "StockModel":[

            ]
         }
      }
   ]
]

Or if you are using string literal in Java you need to add \ before ". If this does not solve your problem please edit your question with your POJO
