Question

怎么用java把一个字符串进行utf8编码？

Answer 1

String text = “字符串”;

byte[] b_utf8 = text.getBytes("UTF-8"); //utf-8

byte[] b_iso88591 = text.getBytes("ISO8859-1"); //iso8859-1

byte[] b_gbk = text.getBytes("GBK"); //gbk

string unicode = getUnicode(text);//unicode

public static String getUnicode(String source) {

String result = "";

for (int i = 0; i < source.length(); i++) {

result += "\\u"+Integer.toHexString((int) source.charAt(i));

}

return result;

}

楼上答得不对，请相信我的方法，已经确认过：

String s="abc";
String s1=URLEncoder.encode(s, "utf-8");
