Yes, it is inherently there. If you don't explicitly extend a class, then the compiler will treat the code as if it automatically extends the Object class. It is kind of like an exponent on a variable in Algebra. If none is written, the variable is considered to be to the first power.
In a related situation, the import statement for the java.lang package is implicit. You never see import java.lang.*;
because the designers felt that the classes in that package were so vital that every class would need to import that package.
