汉字与二进制的互相转换

public class Test {public static void main(String[] args) {String s = "你好";char[] charArray = s.toCharArray();for (int i = 0; i < charArray.length; i++) {System.out.println(Integer.toBinaryString(charArray[i]));}String b = "01001111011000000101100101111101";String str = Long.toHexString(Long.parseLong(b, 2));StringBuffer ch = new StringBuffer();for (int i = 0; i + 4 <= str.length(); i = i + 4) {int j = Integer.parseInt(str.substring(i, i + 4), 16);ch.append((char) j);}System.out.println(ch);}}
