@Makoto: That's simply not true. If you provide a different constructor, the compiler won't supply a parameterless one. — Jon Skeet

@Makoto From the link provided by NPE: if you define at least one constructor, the default constructor is not generated, and then check the best reference for the answer — Luiggi Mendoza

No. If any constructor is defined, there is no default constructor (i assume you mean no-argument constructor) unless you explicitly define it. If no constructors are defined, then the default constructor is implied.

If you provide a constructor for your object then it will be used. If you don't call it java won't call the no-argument constructor thus you have to provide it yourself.

I think the official java documentation here provides some examples which are simple to understand.
