- public class Test {
- /**

- public static void main(String[] args) throws UnsupportedEncodingException {
- // TODO Auto-generated method stub
- Test test = new Test();
- String a = "在";
- test.getStringByteLength(a);
- System.out.println("--------------------------------------");
- String b = "A";
- test.getStringByteLength(b);
- String c = "1";
- test.getStringByteLength(c);
- }
- /**

- private void getStringByteLength(String str) throws UnsupportedEncodingException{
- System.out.println("\""+str+"\"字符所占的字节长度如下:");
- System.out.println("ISO-8859-1:"+str.getBytes("ISO-8859-1").length);
- System.out.println("UTF-8:"+str.getBytes("UTF-8").length);

- System.out.println("GB18030:"+str.getBytes("GB18030").length);
- System.out.println("UTF-16:"+str.getBytes("UTF-16").length);
