What is the difference between Queueable Apex and Future method in Salesforce?

Future method: we cannot monitor the jobs which are in process. this method cannot inside the future or batch class. It will never be queued.
Queueable Apex: It contains the member variable as SObjects or custom Apex Types. using this it will make the ApexAsyncJobs which we can monitor like Scheduled jobs. It can be called from the future and batch class.
