Data Types and Variables Automatic type conversion in Java takes place when Two type are compatible and size of destination type is shorter than source type. All of these Two type are compatible and size of destination type is larger than source type. Two type are compatible and size of destination type is equal of source type. Two type are compatible and size of destination type is shorter than source type. All of these Two type are compatible and size of destination type is larger than source type. Two type are compatible and size of destination type is equal of source type. ANSWER DOWNLOAD EXAMIANS APP
