int asciiValue = (int) firstChar; System.out.println("ASCII value of the first character in the string is: " + asciiValue); 1. 2. 3. 4. 上述代码首先创建了一个字符串变量str,并将其赋值为"Hello"。然后,使用charAt(0)方法获取字符串中的第一个
1)String转换成int类型:在Java 中要将 String 类型转化为 int 类型时,需要使用 Integer 类中的 parseInt() 方法或者 valueOf() 方法进行转换。 int i = Integer.parseInt([String]);//直接使用静态方法,不会产生多余的对象,但会抛出异常 int i = Integer.valueOf(my_str).intValue();//Integer.valueOf(...
