The synchronized method is used in java to lock an object for any shared resource.

If we keep synchronized keyword in front of the method , that will allow only 1 thread at a time to execute that method. Its basically used in multi thread programming.

Is synchronized keyword necessary, in Java, if everything that is modified in a function is local to that function?
No, it is not required if you make sure whatever parameters are updated/modified will be done as atomic references/operations. Atomicity is an alternative to syncronizatiom.
