步骤3: 使用has()方法检查键是否存在 现在你可以使用has()方法来检查是否存在你所需要的 Key。继续在main方法中添加以下代码: // 检查 JSONObject 是否包含指定的 KeyStringkeyToCheck="name";if(jsonObject.has(keyToCheck)){System.out.println("Key \""+keyToCheck+"\" exists in the JSON object.");...
\"age\":30, \"city\":\"New York\"}"; JSONObject jsonObject = new JSONObject(jsonString); // 要检查的属性名 String keyToCheck = "age"; // 判断属性是否存在 boolean exists = jsonObject.has(keyToCheck); // 输出结果 if (exists) { System.out.println("属性 " + keyToCheck + " ...
//Check if key exists if(this.opt(key)!=null) { //key already exists throwx.syntaxError("Duplicate key\""+key+"\""); } //Only add value if non-null Objectvalue=x.nextValue(); if(value!=null) { this.put(key, value);
