HTML stands for Hypertext ___________ Language.
Explanation
HTML stands for Hypertext Markup Language. It is a standard language used for creating and structuring the content of web pages. Markup refers to the process of adding tags and elements to text in order to define its structure and presentation on a web page. HTML uses markup tags to define headings, paragraphs, links, images, tables, and other elements that make up a web page.

Keywords are the ______________ words that have special significance in any language.
-
Pre defined
-
Library
-
Defined
-
Special
Correct Answer
A. Pre definedExplanation
Keywords are the pre-defined words that have special significance in any language. These words are reserved and cannot be used for any other purpose. In programming languages, keywords are used to define the syntax and structure of the code. They have predefined meanings and functions, and using them inappropriately can lead to syntax errors.Rate this question:

The keywords ___________ and ___________ are reserved words but they are not used.
-
Cont,goto
-
Goto,short
-
Super,for
-
Int,char
Correct Answer
A. Cont,gotoExplanation
The keywords "cont" and "goto" are reserved words in programming languages, but they are not commonly used. These keywords are typically used for control flow and looping mechanisms, such as "continue" and "goto" statements. However, using these keywords can make the code more complex and harder to understand, so they are often avoided in favor of alternative control flow structures.Rate this question:

The return type of a constructor is
-
Void
-
Int
-
Float
-
None
Correct Answer
A. NoneExplanation
The return type of a constructor is "none" because constructors do not have a return type. They are special member functions that are used to initialize objects of a class. When an object is created, the constructor is automatically called and it is responsible for initializing the object's data members. Since constructors do not return any value, their return type is "none".Rate this question:

Strings are always specified in
-
Braces
-
Single quotes
-
Double quotes
-
Square brackets
Correct Answer
A. Double quotesExplanation
Strings in programming are typically specified within double quotes. This is because double quotes are the standard way to denote a string literal in many programming languages. Using double quotes makes it clear to the compiler or interpreter that the characters within the quotes should be treated as a string of text rather than as code or a variable. Other options such as single quotes, braces, or square brackets are not commonly used to specify strings in programming.Rate this question:

Javac
-
Java
-
Appletviewer
-
Javah
Correct Answer
A. JavacExplanation
The javac command is used to compile Java source code into bytecode. It takes the source code as input and generates the corresponding bytecode, which can then be executed by the Java Virtual Machine (JVM). The bytecode is an intermediate representation of the code that is platform-independent and can be executed on any device or operating system that has a JVM installed. Therefore, the correct answer is javac.Rate this question:
