When two variables of different data types are involved in the same expression, theJavacompiler uses built-in library functions to trans- form the var...
自动转换为比自身表述范围大的类型。 具体细节请参见官方文档: docs.oracle.com/javase/specs/jls/se7/html/jls-5.html#jls-5.1.4 所以对于 (int 5) / (double 3.0), double 是 64 位 ,int 是 32 位,所以计算的时候会自动将 int 5 转换成 double 5.0, 然后再计算,所以结果便是 double 类型。 明白...
