android(javaOO)遇到的小问题

String/int转换

 

A.String to int

/*

* method 1

*/

int i = Integer.parseInt([String]);

//int i = Integer.parseInt([String], [int radix]);

/*

* method 2

*/

int i = Integer.valueOf([String]).intValue();

B.int to String

String s = String.valueOf([Integer]);

String s = Integer.toString([Integer]);

String s = “”+[Integer];

ps: Double, Folat, Long is as the same way
