上面的代码使用了Java的反射机制来获取不同数据类型的字节大小。通过调用getSize方法并传入相应的数据类型,我们可以获取该数据类型的字节大小。代码执行的结果如下所示: Byte size: 1 Short size: 2 Integer size: 4 Long size: 8 Float size: 4 Double size: 8 ...
eg1: int i=Integer.valueOf(“123”).intValue() 说明:上例是将一个字符串转化成一个Integer对象,然后再调用这个对象的intValue()方法返回其对应的int数值。 eg2: float f=Float.valueOf(“123”).floatValue() 说明:上例是将一个字符串转化成一个Float对象,然后再调用这个对象的floatValue()方法返回其对...
If this integer is out of the range for a byte, the value is narrowed down to a byte. For example, if integer is 270, its byte value is 0001 0000 1110. As byte can only accommodate eight bits, the last eight bits of the given integer is considered as result. In this case the by...

public static BitSet valueOf(long[] longs) Returns a new bit set containing all the bits in the given long array. More precisely, BitSet.valueOf(longs).get(n) == ((longs[n/64] & (1L<<(n%64))) != 0) for all n < 64 * longs.length. This method is equivalent to BitSet.va...
