Nettetjava中int类型取值范围问题. java中int的类型占4个字节,与操作系统无关,要弄明白int的取值范围问题. 首先,我们来看一下byte的取值范围 byte 大小一个字节. 如:1111 1111 为一个字节 但是整型是分正负的 ,所以在计算机中我们用最高位来表示符号位,0表示正数,1表示负数 Nettet6. apr. 2024 · 在JVM中并没有提供boolean专用的字节码指令，而boolean类型数据在经过编译后在JVM中会通过int类型来表示，此时boolean数据4字节32位，而boolean数组会被编译成Java虚拟机的byte数组，此时每个boolean数据1字节占8bit。注意，在整数之间进行类型转换时数值不会发生变化，但是当将整数类型特别是比较大的整数 ...
NettetJava defines four integer types: byte , short, int , and long . All of these are signed, positive and negative values. Java does not support unsigned, positive-only integers. Many other computer languages, including C/C++, support both signed and unsigned integers. However, Java's designers felt that unsigned integers were unnecessary.
The C language provides the four basic arithmetic type specifiers char, int, float and double, and the modifiers signed, unsigned, short, and long. The following table lists the permissible combinations in specifying a large set of storage size-specific declarations. The actual size of the integer types varies by implementation.
