Outline an implementation for the Election service that ensures that its records remain consistent when it is accessed concurrently by multiple clients.
What will be an ideal response?
Suppose that each vote in the form {String vote, int number} is appended to a data structure such as a Java Vector. Before this is done, the voter number in the request message must be checked against every vote recorded in the Vector. Note that an array indexed by voter’s number is not a practical implementation as the numbers are allocated sparsely.
The operations to access and update a Vector are synchronized, making concurrent access safe. Alternatively use any form of synchronization to ensure that multiple clients’ access and update operations do not conflict with one another.
