I have the following interface in Java

public interface IFoo
{
    public abstract void foo();
    public void bar();
}

What is the difference between foo() and bar()? When should I use abstract?

Both seem to accomplish what I want unless I'm missing something subtle?

Update Duplicate of Why would one declare a Java interface method as abstract?

Should I be using abstract methods in this Python scenario?

as seen on Stack Overflow - Search for 'Stack Overflow'
I'm not sure my approach is good design and I'm hoping I can get a tip. I'm thinking somewhere along the lines of an abstract method, but in this case I want the method to be optional.
