This method will always cache values in the range -128 to 127, inclusive, and may cache other values outside of this range. Parameters: i - an int value. Returns: an Integer instance representing i. Since: 1.5 byteValue public byte byteValue() Returns the value of this Integer as a ...
In Java programming, theIntegerclass is used to wrap a value of the primitive typeintin an object. In Java 8, theIntegerclass introduced a useful method calledrange, which creates a sequential range of integers. UsingrangeMethod Therangemethod in theIntegerclass allows you to create a range o...
把1后面全部置为1,最后一步在通过i - (i >>> 1)把左边第一个1之后的全部置为0,这个可以参照一下roundUpToPowerOfTwo的原理图,大家可以这样理解,当i是2的n次方的时候highestOneBit函数和roundUpToPowerOfTwo函数返回的结果是一样的,当i不是2的n次方的时候,roundUpToPowerOfTwo返回的结果是highestOneBit的2倍。

通过源码可以看出,如果用 Ineger.valueOf(int) 来创建整数对象,参数大于等于整数缓存的最小值( IntegerCache.low )并小于等于整数缓存的最大值( IntegerCache.high), 会直接从缓存数组 (java.lang.Integer.IntegerCache#cache) 中提取整数对象;否则会 new 一个整数对象。 那么这里的缓存最大和最小值分别是多少呢?
