How to create a .java file with multiple classes

Question

I have all the below classes declared in a file say ABC.java under
a common package called somepackage
Abstract class A
Void abstract metod1();
Void metod2();
Class B
void method3();
Void method4();
Class C
void method1();
Void method2();
In Client.Java
On compiling the Client.Java I get errors
Import somepackag.*;
Class Samp extents A
void Method1()
Public class Client
A a1 =new Samp(); //error undeclared class A
B b1 = new B1();//error undeclared class B
C c1 = new C1();//error undeclared class C
is it possible to have all the class declared in one file ( i dont need mutiple classes, as this file will be autogenerated , i need all classes in one file) and use the classes inside this in the some client app
regards

As long as you have only one public class and your .java file is named after it you shouldn't have any problem.I did exactly that, but still i get the same error "Cannot find symbol"
i have used the import command on top as import somepackage.*;
