1)将字符串转化为整型; int i = Integer.parseInt(String str); int i = Integer.valueOf(String str).intValue(); 注:Integer.parseInt和 Integer.valueOf 不同,前者生成的是整型,而后者是一个对象,所以要通过intValue()来获得对象的值; 2) 整型转化为字符串: String ... ...

The internal physical representation of the objectschangeswhen we do this. Sometimes bits are simply added or subtracted; other times, as in the float-to-int conversion, the object is completely rearranged. Casting awayconstness.Let's say you want to assign to a const object. This of course ...
