learned to parse a string (decimal, octal and hexadecimal) to int or Integer types using Integer.parseInt(), valueOf() and decode() methods. Learn to convert aJavaStringtointvalue. Note that string can contain a normal decimal value or a different value in other bases or radix. 1. Using...
类比C#中的Convert.ToInt32()方法，Integer.parseInt()同样支持额外参数，用于指定转换的数字进制。例如：这段代码将字符串"11"转换为二进制数3。综上，想要在Java中实现与C#中Convert.ToInt32()方法类似的功能，只需采用Integer.parseInt()方法并适当处理可能出现的异常即可。
