assertThat(bitSet.get(42)).isTrue(); assertThat(bitSet.get(43)).isFalse();Copy 与set和clear类似,我们可以使用get(fromInclusive, toExclusive)方法获取一系列位索引: bitSet.set(10,20);BitSetnewBitSet=bitSet.get(10,20);for(inti=0; i <10; i++) { assertThat(newBitSet.get(i)).isTrue(); ...
第一步,f2i将float转换为int,第二步,int2byte操作码将int转换为byte。 虽然存在将int转换为更小类型(byte,short,char)的操作码,但是不存在反向转换的操作码。这是因为byte,short和char型的数值在入栈之前会转换成int型。byte,short和char型数值的算术运算,首先要将这些类型的值转为int,然后执行算术运算,最后得...
