如题所述
//编写一个JAVA,输入一个字符,输出这个字符及其ASCII值,并输出其前一个字符和后一个字符及其长度
public class baidu {
public static void main(String args[]) {
System.out.println("请输入一个字符");
Scanner scanner = new Scanner(System.in);
String str = scanner.next();
// char[] c=str.toCharArray();
int cc = str.charAt(0);
// char c=str.charAt(0);
int bb = cc - 1;
int dd = cc + 1;
System.out.println("字符是：" + (char) cc + "; ASCII值为" + cc);
System.out.println("前一个");
System.out.println("字符是：" + (char) bb + "; ASCII值为" + bb);
System.out.println("后一个");
System.out.println("字符是：" + (char) dd + "; ASCII值为" + dd);
