  • What is the equivalent of the C# var keyword in Java?
    The var reserved type name in Java is nearly identical to the var keyword in C# in that both allow for implicit typing (see below for important differences) var in Java can only be used for implicit type inference in the following contexts (as enumerated in JEP 286: Goals): local variables with initializers; indexes in the enhanced for-loop
