Java中Integer.MAX_VALUE的含义 Integer.MAX_VALUE是Java中的一个常量,它表示整数数据类型int的最大可表示值。 Integer.MAX_VALUE的值是2,147,483,647。这意味着在一个标准的32位Java虚拟机中, int数据类型可以表示的最大整数值为 2,147,483,647,或者说 2^31 - 1。 如果你尝试存储一个大于Integer.MAX_VAL...
最小值:Integer.MIN_VALUE= -2147483648 (-2的31次方) 最大值:Integer.MAX_VALUE= 2147483647 (2的31次方-1) 2、基本类型:short 基本类型:short 二进制位数:16位 包装类:java.lang.Short 最小值:Short.MIN_VALUE=-32768 (-2的15此方) 最大值:Short.MAX_VALUE=32767 (2的15次方-1) 3、基本类型:long...
模式:public final static <type> varName = <value>; 通常用于声明可以在类的外部使用的类常量。在引用这样的类常量时需要用类名加以限定。在上面的示例中,另一个类可以用 MyClass.MAX_OBJECTS 形式来引用 MAX_OBJECTS 常量。 10) strictfp 严格,精准 strictfp的意思是FP-strict,也就是说精确浮点的意思。在J...

Ideal Graph的构建是在解析字节码的时候,根据字节码中的指令向一个空的Graph中添加节点,Graph中的节点通常对应一个指令块,每个指令块包含多条相关联的指令,JVM会利用一些优化技术对这些指令进行优化,比如Global Value Numbering、常量折叠等,解析结束后,还会进行一些死代码剔除的操作。生成Ideal Graph后,会在这个基础上...
