第四章第八题(给出ASCII码对应的字符)(Find the character of an ASCII code)


*4.8(给出ASCII码对应的字符)编写一个程序,得到一个ASCII码的输入(0~127之间的一个整数),然后显示该字符。

下面是一个运行示例:
Enter an ASCII code: 69
The character for ASCII code 69 is E

*4.8(Find the character of an ASCII code) Write a program that receives a character and displays its ASCII code (an integer between 0 and 127).

Here is a sample run:
Enter an ASCII code: 69
The character for ASCII code 69 is E

下面是参考答案代码:

import java.util.*;

public class FindASCIICodeQuestion8 {
public static void main(String[] args) {

int decimal, binary;
Scanner input = new Scanner(System.in);

System.out.print("Enter an ASCII code: ");
decimal = input.nextInt();
if(decimal >= 0 && decimal <= 127)
{
binary = (byte)decimal;
System.out.printf("The chararter for ASCII code %d is %c", decimal, binary);
}
else
System.out.println("Invalid Input");

input.close();
}
}

运行效果:

第四章第八题(给出ASCII码对应的字符)(Find the character of an ASCII code)_代码规范

注:编写程序要养成良好习惯
1.文件名要用英文,具体一点
2.注释要英文
3.变量命名要具体,不要抽象(如:a,b,c等等),形式要驼峰化
4.整体书写风格要统一(不要这里是驼峰,那里是下划线,这里的逻辑段落空三行,那里相同的逻辑段落空5行等等)
5.普通变量,方法名要小驼峰,类名要大驼峰,常量要使用全部大写加上下划线命名法
6.要学习相应的代码编辑器的一些常用快捷键,如:快速对齐等等
