One, automatic type conversionIn Java programs, it is often necessary to convert data between different basic data types. For example:，the int variable score1 in the code can perform the assignment directly for the double type variable score2, and The result is: 82.0This conversion is called automatic type conversion . Of course, automatic type conversions are re
