   • what is a graphics context (In Java)?

     Top Answer

     Answered Oct 22, 2010 · 8 votes

     "Context" is a generic name that many java developers use for classes that carry state information. So are bound to see a lot of different class names containing context.

     Graphic context in desktop Java usually means java.awt.Graphics or java.awt.Graphics2D classes. They carry information about drawing properties: colors, line properties, clipping regions, etc..

   • What is the simplest way to display a graphics drawing in Java AWT?

     Top Answer

     Answered Feb 02, 2017 · 0 votes

     According to my tests:

     class C extends Component { public C() { setSize(200, 200); setVisible(true); } public void paint(Graphics g) { g.drawRect(0, 0, 100, 100); }}

     will not be displayed because presumably it needs something to be added to.

     class C extends Container { public C() { setSize(200, 200); setVisible(true); } public void paint(Graphics g) { g.drawRect(0, 0, 100, 100); }}

     will not be displayed because it is a container so it needs other things to be added to it.

     class C2 extends Window { public C2() { super(new Frame()); setLocation(100, 100); setSize(200, 200); setVisible(true); } public void paint(Graphics g) { g.drawRect(0, 0, 100, 100); }}

     can be displayed but has nothing to grab around and it even doesn't show on the task bar so its a useless thing unless you add it somewhere.

     So

     class C extends Frame { public C() { setSize(200, 200); setVisible(true); } public void paint(Graphics g) { g.drawRect(0, 0, 100, 100); }}

     is your solution as the first that is both a Component and a Container.

   • What is System, out, println in System.out.println() in Java

     Top Answer

     Answered Aug 17, 2012 · 8 votes

     The first answer you posted (System is a built-in class...) is pretty spot on.

     You can add that the System class contains large portions which are native and that is set up by the JVM during startup, like connecting the System.out printstream to the native output stream associated with the "standard out" (console).

   • What is a constant in Java

     Top Answer

     Answered Feb 08, 2016 · 6 votes

     A constant is value that cannot be changed. For example 5, 0.5 , "abcd" etc.

     Lets consider Java :

     int i = 5; // Here 5 is constant but the reference (i) can change and point to 6. i.e, the value 5 is immutable, but the reference (i) is mutable.-

     Adding the final keyword to the above statement :

     final int i = 5; // Here the keyword final ensures that the reference cannot point to any other value.

     Thus i becomes a compile time constant and its value is passed in the byte-code itself.

     Note that a reference could point to a constant value (immutable object ) or a mutable value.

     Technically speaking, immutable values aren't same as constants in case of reference types (except String).

   • What is a consumer in Java?

     Top Answer

     Answered May 12, 2021 · 6 votes

     Despite various info you can find about "Producer/Consumer" pattern, in Java there is a specific functional interface called Consumer, which belongs to the package java.util.function. That is just one of the various functional interfaces (there are 4 main ones: Consumer, Function, Predicate and Supplier, along with additional subinterfaces) which Java makes available to be used in particular for defining lambda expressions, to be used in combination with Java Stream. If you look at the specification, Consumer, this functional interface is defined over a specific target type T and exposes a method called accept, whose signature is the following:

     void accept(T t);-

     So, the Consumer functional interface is particularly useful when you want to define a function that performs some actions over an instance of type T and doesn't return any value. The most typical usage is when you want to scroll all elements of a java.util.Iterable object and you want to perform an action over each element, and this is possible by just passing a lambda expression to the default method forEach exposed by the interface.

     Here is an example:

     List<String> myList = List.of("Element1", "Element2", "Element3");myList.forEach(s -> System.out.println(s));-

     As you can see, the above code just creates an immutable List of String elements, and the method forEach just perform the action specified by the Consumer in input (which is the lambda expression s -> System.out.println(s)), which simply prints each element of the list in the standard output. Of course there are infinite possibilities, but my intentions is just to give you an idea of what a Consumer is in Java.

   Vector is like the dynamic array which can grow or shrink its size. Unlike array, we can store n-number of elements in it as there is no size limit. It is a part of Java Collection framework since Java 1.2. It is found in the java.util package and implements the List interface, so we can use all the methods of List interface here.
