JAVA中怎样实现unicode与ascii码的相互转化
1、ASCII码 string s = "梁"; System.Text.Encoding GB2312 = System.Text.Encoding.GetEncoding("GB2312"); byte[] gb = GB2312.GetBytes(s); 这时gb中有两个数字193（11000001），186（10111010） 2、非ASCII编码 string s = "梁"; System.Text.Encoding GB2312 = System.Text.Encoding.GetEncoding("GB2312"); byte[] gb = GB2312.GetBytes(s); 这时gb中有两个数字193（11000001），186（10111010） 3、Unicode Unicode当然是一个很大的集合，现在的规模可以容纳100多万个符号。每个符号的编码都不一样。C#中如果你想看看某个汉字的Unicode编码可以使用如下代码： string s = "梁"; byte[] unicode = Encoding.Unicode.GetBytes(s); 这时unicode中有两个数字129（10000001），104（1101000）
java中ASCII表的字母和数字相互转化的问题
public class welcome {
public static void main(String[] args) {
String str="gjalg";
char[] cha=str.toCharArray();
for(char s:cha){
System.out.println("ascii的值"+s);
System.out.println("+3后的字母"+(char)(s+3));
}
}
}
你可以看一下ascii码表中对应的值
java字符串ascii转换为数字
你的问题描述和你的提问题目貌似不一样的哦。虽然我很不明白你的疑惑，但是我根据你的题目猜想就是把任意的字符串转换为ascii码，对吗？如果是这样的，只需要把字符串的每个字符都转为int型，就可以得到你想要的ascii码了。
代码可以参考如下：
public
class
StringToAscii
{
public
static
void
main(String[]
args)
{
String
s
=
"abc123"
;
int[]
arr
=
new
int[s.length()];
for
(int
i
=
;
i
s.length()
;
i
++
)
{
arr[i]
=
s.charAt(i);
System.out.print(arr[i]
+
","
);
}
}
}
JAVA把ASCII码转变为字符串
public class TTTTT {
public static void main(String[] args) {
String string = "1041011081123210910133";
System.out.println(asciiToString(string));
}
public static String asciiToString(String text) {
StringBuilder builder = new StringBuilder();
for (int i = 0; i text.length(); i++) {
if (text.charAt(i) = '2' i = text.length() - 3) {
int code = Integer.parseInt(text.substring(i, i + 3));
builder.append((char) code);
i += 2;
} else {
int code = Integer.parseInt(text.substring(i, i + 2));
builder.append((char) code);
i += 1;
}
}
return builder.toString();
}
}
你这编码很怪啊，结果竟然是help me!
1041011081123210910133
解析起来很麻烦那，不是3位3位的。
