当在一个表达式中混合有不一致类型的数据时,它们都被转换为同一类型。这是通过使用Java类型升级规则(type promotion rule)完成的。下面的陈述那一个是不正确的。 ( ) A. 所有的char、byte与short都被升级为int。假如有一个操作数是long类型,整个表达式就全部升级为long类型。 B. 假如有一个操作数是float类型,整个表达
Java programming language is a statically typed language. It means that every variable and every expression has a type that is known at compile time. Java language is also a strongly typed language because types limit the values that a variable can hold or that an expression can produce, limit...
When mixed with other data types in expressions, the resulting data type follows the rules shown in Numeric type promotion in expressions. See also Storing values of one numeric data type in columns of another numeric data type. When two decimal values are mixed in an expression, the scale...
In such cases either type promotion or demotion takes place.Ruleschar or short type operands will be converted to int during an operation and the outcome data type will also be int. If an operand of type long double is present in the expression, then the corresponding operand will also be...
