Java allows constructors to be overloaded, meaning you can have multiple constructors in a class, each with a different parameter list. The correct constructor to use is determined at runtime based on the arguments you provide when creating the object. Let’s add another constructor to ourVehic...

ValueMeaning "r" Open for reading only. Invoking any of thewritemethods of the resulting object will cause anjava.io.IOExceptionto be thrown. "rw" Open for reading and writing. If the file does not already exist then an attempt will be made to create it. "rws" Open for readin...
Invocation of Base Class Constructor in Java Like C++, Java insists that a constructor for a base class be called before the constructor for a derived class. The syntax is a bit simpler, however; the initial line of the code for the derived class constructor may consist of a “call” to...
2. In this case methods is set to 'private', meaning if I do a = MyProject, there would be an error. So how can I use this class apart from set access to public (like project1 = MyProject, but this gives an error)? 3. If I want to have constant and normal propert...
Otherwise, the meaning of the expression name is the variable declared by the declaration. If the expression name appears in an assignment context, invocation context, or casting context, then the type of the expression name is the declared type of the field, local variable, or parameter after...
Explanation: The describe method is added to the Book prototype, meaning all instances of Book share the same describe method. This is more efficient than if describe were defined inside the constructor, which would result in a new function for every book instance. 3. Return Values Best Practic...
HorizontalAlignment RIGHTThe horizontal alignment is right-aligned, meaning that cell contents are aligned at the right edge of the cell, even in Right-to-Left mode. HorizontalAlignment JUSTIFYThe horizontal alignment is justified (flush left and right). HOME...
It is possible for a class to have no constructor. (An important distinction to draw here is that the JVM does not require all class files to have a constructor; however, any class defined in Java does have a default constructor if a constructor is not explicitly declared....
See ContentResolver#query(Uri, String[], String, String[], String) ContentResolver.query() for documentation on the meaning of the parameters. These will be passed as-is to that call. Java documentation for android.content.CursorLoader.CursorLoader(android.content.Context, android.net.Uri, java....
