In[25]:not1==22Out[25]:True 上面讲到,or, and, not的优先级是依次递增的,优先级跟小学数学中先乘除后加减但括号里面的更优先是一样的。 那么小猿们猜猜下面的代码会输出什么: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 print(''or'b'and'c') 优先级and大于or,所以先计算and: (1)先计算...
A JavaScript Boolean represents one of two values:trueorfalse. Boolean Values Very often, in programming, you will need a data type that can only have one of two values, like YES / NO ON / OFF TRUE / FALSE For this, JavaScript has aBooleandata type. It can only take the valuestrueor...

bastore指令:Store intobyteorbooleanarray In Oracle’s Java Virtual Machine implementation,booleanarrays in the Java programming language are encoded as Java Virtual Machinebytearrays, using 8 bits perbooleanelement. 在Oracle 的 Java 虚拟机实现中,Java 中的 boolean 数组被编码为 byte 数组,每个 boolean...
为保证 Java 的移植能力,基本类型大小不可改变。 位于栈,直接存储 ”值“,而非引用的自动变量。 boolean只有两个值:true与false,可以使用单个字节进行存储,具体大小没有明确规定。JVM 会在编译时期将boolean类型的数据转换为int,使用1来表示true,0来表示false。JVM 并不直接支持boolean数组,而是使用byte数组、int数组...
