Just adding to what Denise Roßberg has mentioned in his answer. It is possible to have same name for both instance and local variables because local variables have a block level scope. They can be accessed only within the block { } in which they are defined. On the other hand, instance variables have a class level scope and can be accessed anywhere within the class. One doesn't know about the other.

Yes. To avoid conflicts you need to use the keyword this. For example you have an instance variable int number and also a local variable int number. If you mean the local variable you can write number. And if you mean your instance variable you have to write this.number.
