The Java Virtual Machine encodes boolean array components using 1 to represent true and 0 to represent false. Where Java programming language boolean values are mapped by compilers to values of Java Virtual Machine type int, the compilers must use the same encoding. 1. 2. 3. 4. 5. 6. 7....
Instead, expressions in the Java programming language that operate on boolean values are compiled to use values of the Java Virtual Machine int data type. 尽管Java 虚拟机定义了一个布尔类型,但是它只提供了非常有限的支持,并【没有】专门用于对【boolean 值】进行操作的 Java 虚拟机指令。相反,Java 中...
