2.一个字节等于8位 1byte = 8bit char占用的是2个字节 16位,所以一个char类型的可以存储一个汉字。 整型: byte:1个字节 8位 -128~127 short :2个字节 16位 int :4个字节 32位 long:8个字节 64位 浮点型: float:4个字节 32 位 double :8个字节 64位 注:默认的是double类型,如3.14是double类型...
在Java中,我们可以通过使用Character类中的方法来判断char占用的字节数。Character类提供了SIZE字段来表示char类型所占的位数,即16位(2个字节)。我们也可以通过ByteBuffer类来检查char的字节数。 通过Character类判断 publicclassCharSizeExample{publicstaticvoidmain(String[]args){System.out.println("Char size in byt...
private char[] getChars (byte[] bytes) { Charset cs = Charset.forName ("UTF-8"); ByteBuffer bb = ByteBuffer.allocate (bytes.length); bb.put (bytes); bb.flip (); CharBuffer cb = cs.decode (bb); return cb.array(); } http://sun.calstatela.edu/~cysun/documentation/java/1.5.0-s...
Well, it so happens that addition of bytes in Javais defined to return anint. This, I believe was because the Java Virtual Machine doesn't define byte operations to save on bytecodes (there is a limited number of those, after all), using integer operations instead is an implementation de...
byte 是字节数据类型 ,是有符号型的,占1 个字节;大小范围为-128—127 。 char 是字符数据类型 ,是无符号型的,占2字节(Unicode码 );大小范围 是0—65535 ; char是一个16位二进制的Unicode字符,JAVA用char来表示一个字符 。 可能看到上面这句话的时候,往往不会在意char是不是Unicode字符,当时它却是我们理清...
这意味着将一个byte表示的 Latin-1 字符转换成 Java 的char或者用于表示 Unicode 码位的int时根本不需...
