System.out.println(Integer.valueOf(a)); // char转int 使用Integer.parseInt(String s) int a1=Integer.parseInt(a+""); System.out.println(a1); // int转char // 1、如果int的范围为[0,9],使用数字和字符'0'做运算,得到数字字符的ASCII码,再使用强制类型转换,注意不能直接进行强制类型转换 int b=...

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(...
