java中有没有Unicode 与 Ansi 码互转的方法？

Question

在asp中可以通过
asc()  和 chr()转换    不知道java中用什么方法？

Answer 1

new String(str.getBytes("ISO8859-1"),"UTF-8");

Answer 2

new String(str.getBytes("ISO8859-1"),"UTF-8");还要怎么详细呢?

Answer 3

public class thisx {
public static void main(String[] args){
String str = "12333";
String asc = new String(str.getBytes("ISO-8859-1"),"UTF-8");
System.out.println(asc);
}
}
//第4行错了 兄弟看看咋回事

Answer 4

public class UnicodeTest {    public static void main(String args[]) {
        UnicodeTest UT = new UnicodeTest();
        UT.test1();
    }    public void test1() {
        String str = "你好测试信息abc123";
        try {
            byte[] b = str.getBytes("GBK");
            System.out.println(str + " -(GBK)编码: " + bytesToHexStr(b));
            System.out.println("");            str = new String(b, "GBK");
            System.out.println("从GBK编码 " + bytesToHexStr(b) + " 重新转换为字串: "
                    + str);
            System.out.println("-------------------------------------");            
            b = str.getBytes("UnicodeBigUned");
            System.out.println(str + " -(UCS2)编码: " + bytesToHexStr(b));
            System.out.println("");            str = new String(b, "UnicodeBigUned");
            System.out.println("从(UCS2)编码 " + bytesToHexStr(b) + " 重新转换为字串: "
                    + str);
            System.out.println("-------------------------------------");
            
            
            b = str.getBytes("GB18030");
            System.out.println(str + " -(GB18030)编码: " + bytesToHexStr(b));
            System.out.println("");            str = new String(b, "GB18030");
            System.out.println("从(GB18030)编码 " + bytesToHexStr(b) + " 重新转换为字串: "
                    + str);
            System.out.println("-------------------------------------");
            
                        b = str.getBytes("ASCII");
            System.out.println(str + " -(ASCII)编码: " + bytesToHexStr(b));
            System.out.println("");
            
            str = new String(b, "ASCII");
            System.out.println("从(ASCII)编码 " + bytesToHexStr(b) + " 重新转换为字串: "
                    + str);
            
        } catch (Exception e) {
            e.printStackTrace();
        }
    }    private String bytesToHexStr(byte[] b) {
        if (b == null)
            return "";
        StringBuffer strBuffer = new StringBuffer(b.length * 3);
        for (int i = 0; i < b.length; i++) {
            strBuffer.append(Integer.toHexString(b[i] & 0xff));
            strBuffer.append(" ");
        }
        return strBuffer.toString();
    }}

Answer 5

try {
String str2 = new String(str.getBytes("ISO-8859-1"),"UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
