如何将String类型转换为ascii码或者其编码？

如何将String类型转换为ascii码或者其编码，我想做密码加密！！
各位谁有好的建议？

String(byte[] ascii, int hibyte)
Deprecated. This method does not properly convert bytes into characters. As of JDK 1.1, the preferred way to do this is via the String constructors that take a charset name or that use the platform's default charset.

不知道byte可以不可以，我觉得应该可以吧。字节就是构成文件的最低元素了。用
String类的getBytes()方法就可以把String拆成byte.然后你再对BYTE进行加密行么？

如用String类的getBytes()方法就可以把String拆成byte，
这个函数在那个包下？
望告知！谢先

//转过去

char temChr ;
int ascChr ;
int i ;
String ss = "" ;
String rtStr = "地从" ;
int length = rtStr.length() ;
for ( i = 0 ; i < length ; i++ )
{
temChr = rtStr.charAt( i ) ;
ascChr = temChr + 0 ;
ss = ss + "&#x" + Integer.toHexString( ascChr ) + ";" ;

//转回来

String sArray[] = ss.split(";");
byte bArray[] = new byte[2 * sArray.length];
for (i = 0 ; i < sArray.length; i++) {
try {
int tmp = Integer.parseInt(sArray[i].substring(3), 16);
System.out.println(">>>>>int value is " + sArray[i].substring(3));
bArray[i*2 + 1] = (byte)(tmp & 0xff);
bArray[i*2 ] = (byte)((tmp >> 8) & 0xff);
} catch (NumberFormatException e) {
e.printStackTrace();
}
}
System.out.println("convert to orginal String is " + new String(bArray));

这个完成了！！谢谢
散分~！
那如何将byte转换为String类型？？？？？？？？？？？？？？？？？？？？？解决后散分

byte[] b;
String a=new String(b);
你便可以得到转换后的String,这个方法简单又方便。
