Which is true about an anonymous inner class?
A lot of things are true about them. What is it that you want to know?
Compare Do-While with While Statements?
A Do-While loop looks like this:
do {
loop body
} while (condition);
and a While loop looks like this:
while (condition) {
loop body
}
The main difference is that the loop body is always run once in the Do-While loop, then the condition is checked to see if the loop should keep running. In a While loop, the condition is checked first, and it will not run the loop body at all if the condition is false.
What is high-level language compiled?
Compiling a high-level language means that the high-level source code (what is typed by the programmer) is being converted to machine code (binary, i.e. 0's and 1's) that the local computer can execute. In interpreter languages, the source code is first converted to byte code, which is either run directly (slower, but very portable), or interpreted by a virtual machine (see JVM) into machine code, and then executed (faster, but somewhat less portable). If an error is found the compilation stops and the errors are displayed.
default : <statement>;
i.e.
switch (value) {
case 1 : do_this(); break;
case 2 : do_that(); break;
default : do_whatever();
}
An Iterator is a java feature using which we can loop through every single element of a collection and perform operations on them. It is extremely useful because we don't have to worry about the collection size or whether we will get index out of bounds exceptions while looping through a collection
Ex:
ArrayList lst = new ArrayList();
//code that populates the list
Iterator ir = lst.iterator();
Here itr is the iterator that will help the code loop through each element of the collection.
Do you mean there should be a new skin color?If you do mean that, I think the new party should be sloxican(black people mixed with asians).
What is the difference between an actual type and declared type variable?
I believe a declared type is the type used when first declaring a variable.
And the actual type is the type that the variable is actually assigned, which
could be the declared type or any subtype of that type. So given
GeometricObject shape = new Triangle();
GeometricObject is the declared type and Triangle is the actual type. To
demonstrate this more clearly the following statements are all correct.
GeometricObject shape; // shape declared to be a GeometricObject
shape = new Triangle(); // actual type assigned = Triangle
shape = new Square(); // now shape refers to a Square object
This is the basis of polymorphism. It allows you to write methods which have
for parameters more general types but are able to handle subtypes differently.
This makes your code more general and reusable.
A DTD is the original type of XML schema. XML Schemas are used to formally describes the contents of an XML document. An XML schema describes the shape of the XML document, defining the data, sub elements or attributes it can contain, along with the number of times given entities can occur. A document type definition (DTD) is a set of markup declarations that define a document type for an SGML-family markup language (SGML, XML, HTML). A Document Type Definition (DTD) defines the legal building blocks of an XML document. It defines the document structure with a list of legal elements and attributes.

What are factory methods in java?
A factory class is any class which is used to create instances of other classes. The methods which create those classes are the factory methods.
For example, the BorderFactory class has a variety of methods for creating instances of the different types of the Border classes.
BorderFactory.createEmptyBorder();
BorderFactory.createEtchedBorder();

Palindrome number is a number like 121 which remains the same when its digits are reversed. To find this number in a simple java program, just follow the below way. sum = 0; while(n>0) {
r=n % 10; sum=concat(r); n=n / 10; } print r;
How long does it take to write an application with a programming language?
It can be one minute for one person, and can be ten year for thousand people.
Write a java that computes the value of 2?
Compute means to calculate. What do you want to "compute", if you already know it is 2? If you want to show the value:
System.out.println("Your number is " + 2);

Can you use struts in a desktop application?
If the desktop application you mean would be run on a web browser - Then the answer is YES. STRUTS is an open source framework used for the development of web based java applications using other J2EE technologies like JSP, Servlets and XML.
False. A method with the same signature in both the superclass and its subclass is known as method overriding, and is a valid concept in Java.
Dynamic polymorphism is a programming method that makes objects with the same name behave differently in different situations. This type of programming is used to allow Java Scripts to run while playing a game on the computer, for example.
