// 将字符转化为ASCII码intascii=(int)ch;System.out.println("字符 '"+ch+"' 的ASCII码为:"+ascii); 1. 2. 3. 三、完整代码示例 下面是完整的Java代码示例: importjava.util.Scanner;publicclassMain{publicstaticvoidmain(String[]args){// 创建一个Scanner对象Scannerscanner=newScanner(System.in);Syst...
下面是一个简单的Java程序,可以将输入的字符转换为ASCII码并输出: importjava.util.Scanner;publicclassCharToASCII{publicstaticvoidmain(String[]args){Scannerscanner=newScanner(System.in);System.out.print("请输入一个字符:");charch=scanner.next().charAt(0);intascii=(int)ch;System.out.println("字符 ...
这样的输出结果是Ascii码: 那到底如何转为真正要用的int类型数据呢,最简单的方法, char类型字符减去'0'就可以了,直接上代码: 1publicclassLeet {2publicstaticvoidmain(String[] args) {3charc = '5';4inti = c - '0';//减去'0'就是想要的int类型数据了5System.out.println(i);6}7}...
charin='2';int iVar=in;System.out.println(in);System.out.println(iVar);//输出:// 2// 50 想当然的做法果然错了:期望取出来的 int 2,实际却是 int 50。 当char 直接 赋给 int 时,实际上是把 char 变量的ASCII 码赋给 int类型,因此取出char 变量的数值不能通过直接转换成int的方法实现。 方法一...
越是常用的字符,字节越短,最前面的128个字符,只使用1个字节表示,与ASCII码完全相同。 编号范围 字节 0x0000 - 0x007F 1 0x0080 - 0x07FF 2 0x0800 - 0xFFFF 3 0x010000 - 0x10FFFF 4 五、Java char 和 String 的区别 由于Java 采用的是 16 位的 Unicode 字符集,即 UTF-16,所以在 Java 中 char...
