java中的char占几个字节实例分析

public class Test {     public static void main(String[] args) {     String str= "中";     char x ='中';     byte[] bytes=null;     byte[] bytes1=null;     try {       bytes = str.getBytes("utf-8");       bytes1 = charToByte(x);     } catch (UnsupportedEncodingException e) {       // TODO Auto-generated catch block       e.printStackTrace();     }     System.out.println("bytes 大小："+bytes.length);     System.out.println("bytes1大小："+bytes1.length);   }   public static byte[] charToByte(char c) {      byte[] b = new byte[2];      b[0] = (byte) ((c & 0xFF00) >> 8);      b[1] = (byte) (c & 0xFF);      return b;    } }
