字符串转Ascii码
private static String convert(String str) {
String tmp;
StringBuffer sb = new StringBuffer(1000);
char c;
int i, j;
sb.setLength(0);
for(i = 0;i<str.length();i++){
c = str.charAt(i);
if (c > 255) {
sb.append("\\u");
j = (c >>> 8);
tmp = Integer.toHexString(j);
if (tmp.length() == 1) sb.append("0");
sb.append(tmp);
j = (c & 0xFF);
tmp = Integer.toHexString(j);
if (tmp.length() == 1) sb.append("0");
sb.append(tmp);
}
else {
sb.append(c);
}
}
return(new String(sb));
}
Ascii码转字符串
byte[] bb = (String.valueOf("\u7f16\u7801")).getBytes("UTF-8");
String cc = new String(bb, "UTF-8");
