How do you convert int to long?

Int can be converted to long in two simple ways:

  1. Using a simple assignment. This is known as implicit type casting or type promotion, the compiler automatically converts smaller data types to larger data types.
  2. Using valueOf() method of the Long wrapper class in java which converts int to long.

Can we convert long to int in java?
