Sorry, I typed a wrong Factory class. It should be:
class Factory{
public static Interface1 getInterface(int type){
if(type == 1){
return new Imple1();
}else if(type ==2){
return new Imple2();
}
return null;
}
}
In main method:
public static void main(String []args){
Interface1 inter1 = Factory.getInterface(1);
}
