Java中ASC码与字符互相转换

每一个字符都会有对应的ASCII码，下面举例在Java中将两者互相转换：

<span style="white-space:pre"></span>String a = "asd";char[] ch = a.toCharArray();for (int i = 0; i < ch.length; i++) {int backnum = (int) ch[i];System.out.println("ch"+ch[i]+":" + backnum);char strChar = (char) backnum; System.out.println("strChar :" +strChar);}
