可以看到一个char类型的变量是可以直接和数字做运算的,相当于用它的ASCII码值做运算。由可以得出java中char和int型的转化方法,需要注意的是,这个转化不是获取char字符的ASCII码。比如说char a='3',要将a转化为型得到的结果应该是int型的数字3,而不是字符‘3’的ASCII码51。所以千万不能Integer.valueOf(char c...
如何用java获得字符串的ASCII值 使用Integer.valueOf就可以直接将char类型的数据转为十进制数据表现形式. intvalue=Integer.valueOf('1');//49 int value=Integer.valueOf('a');//97 如下所示: ASCII 码使用指定的7 位或8 位二进制数组合来表示128 或256 种可能的字符。标准ASCII 码也叫基础ASCII码,使用7...
