今天在搜尋tree的實(shí)現(xiàn)，找到了這段代碼，覺(jué)得很有用但是還沒(méi)想到怎么用，先保存在這里
一般用匿名內(nèi)部類(lèi)實(shí)現(xiàn)callback
public interface YourInterface {
public void interfaceMethod();
}
public class YourClass{
public void classMethod(YourInterface yInterface)
{
......
yInterface.interfaceMethod();
......
}
public static void main(String[] args)
{
YourClass yClass = new YourClass();
yClass.classMethod(new YourInterface()
{
public void interfaceMethod()
{
//do sth
System.out.print("hello world.");
.......
}
});
}
