JAVA Unicode编码与中文互换

中文转Unicode

 public static String toUnicode(String s) {
	        String s1 = "";
	        for (int i = 0; i < s.length(); i++) {
	            s1 +="//u" +  Integer.toHexString(s.charAt(i) & 0xffff);
	        }
	        return s1;
	    }

Unicode转中文

 public static String fromUnicode(String unicode){
				String  str = "";
				String[] hex = unicode.split("//u");  
				System.out.println(hex.length);
				for(int i=1;i<hex.length;i++){         
					int data = Integer.parseInt(hex[i],16); 
					str+=(char)data; 
				}
				return str;
