class hello{
public void notused()
{
System.out.println("not used");
}
public static void main(String argv[])
{
System.out.println("Hello");
}
}
this is a full execlutable program,and it hava only one entry point "main"!
and i test a c++ file,it will remove the unused funcitons "notused":
[licheng@Soft04 ~]$ cat hello.cpp
#include
class hello
{
public:
hello()
{
}
void notused()
{
std::cout << "not used";
}
void used()
{
std::cout << "used";
}
~hello()
{
}
}hi;
int main()
{ hello t;
t.used();
return 0;
}
