a的ASCII码是97 0的ASCII码是48 在Java中,你可以通过强制类型转换,将ASCII码转换成字符,或者将字符转换成ASCII码。这是一种非常简单的操作。 ASCII码到字符的转换 在Java中,将ASCII码转换为字符可以使用强制类型转换,具体示例如下: publicclassAsciiToChar{publicstaticvoidmain(String
输入数据格式:"%c" 输出数据格式:"%c,%d\n" 或“%c” 注:大写字母A的ASCII码值是:65 小写字母a的ASCII码值是:97 import java.util.Scanner; public class hello { public static void main(String[] args) { System.out.println("Please enter a char:"); Scanner scan = new Scanner(System.in);...

A different (and simpler) approach is to take a given string and check if it's possible to encode it into ASCII. import java.nio.charset.Charset; public class StringUtils {public static boolean isPureAscii(String v) { return Charset.forName("US-ASCII").newEncoder().canEncode(v); ...

Java语言使用Unicode作为其字符码集。Unicode能够表示多种语言的字符,覆盖范围广。分析选项: - **(A) ASCII**:仅支持基本拉丁字符,Java不局限于此。 - **(B) BCD**:二进制编码十进制,与字符编码无关。 - **(C) DCB**:非常见术语,可能为干扰项。 - **(D) Unicode**:正确,尽管题干拼写为“Un ic...
