A scale of 1:10000 means 1cm on the map represents 10000cm (100m) in real life. So 5cm represents 5 × 100 = 500m. Option C is correct.

This statement is valid in Java. The 'new Integer(12)' creates an Integer object through autoboxing, and 'int _samId' unboxes it to a primitive int. The double underscore in '_samId' is a valid variable name in Java. This is syntactically correct and will compile.

Boolean is the correct wrapper class name for the primitive boolean in Java. Option A is the primitive type (not wrapper), while options B and C are misspelled. Java wrapper classes follow specific capitalization rules.

Sun Microsystems rebranded Java 1.5 as Java 5.0 in 2004 to better reflect its significant evolution. While 1.5 remains the internal version string (used by the JVM and developer tools), 5.0 is the external product version used for marketing and branding purposes.

The code formats the current date and appends the integer 12. If the date was Aug 2, 2010, the output 'Today is Aug 2, 201012' is produced because System.out.print does not add spaces or newlines between the date string and the integer.

Java originally had 50 keywords. However, 'const' and 'goto' are reserved but not used. 'true', 'false', and 'null' are literals, not keywords. Depending on the version and definition, 48 is often cited as the number of active keywords.

While the method code itself is stored in the Code Segment/Method Area, the execution of methods (including local variables and call frames) occurs on the Stack. However, the question is slightly ambiguous as 'stored' usually refers to the Method Area.

In Java, the 'java.lang.Object' class is the root of the class hierarchy. Every class in Java, whether user-defined or built-in, inherits from Object either directly or indirectly.

The code contains several errors: 'NowString()' is a constructor name that doesn't match the class 'NowS', and 'Super.Sam(12)' is invalid syntax for calling a superclass constructor (it should be 'super(12)'). These issues cause a compilation error.

Java does not support multiple inheritance of classes to avoid complexity and the 'diamond problem'. However, it allows a class to implement multiple interfaces, effectively providing a way to achieve the benefits of multiple inheritance.

An interface in Java is 100% abstract - it can only contain abstract method declarations (and constants). Unlike abstract classes which can have both abstract and concrete methods, interfaces cannot have any implemented methods. This is the fundamental definition of an interface in Java - it provides a contract without implementation.

In Java, static variables are initialized when the class is loaded, and initializer blocks (both static and instance) run before the constructor body. Static blocks run once at load time; instance blocks run every time an object is created, just before the constructor.

Constructors are not inherited in Java - each class must have its own constructors. When a subclass is instantiated, it calls the superclass constructor (implicitly or explicitly via super()), but it does not inherit the constructor itself. Public instance variables, protected members, and primitive elements are all inherited by subclasses.

The code uses assignment (=) instead of equality (==). In 'if(var = true)', the assignment happens first (var becomes true), then the condition evaluates the assigned value. Since true is truthy, the if-block executes, printing 'TRUE'. This is a common bug - the programmer likely meant to compare (==) but accidentally assigned. There's no compilation or runtime error - Java allows boolean assignment in conditions.

Ablutophobia is the specific phobia relating to washing, bathing, or cleaning. The term comes from the Latin 'abluere' (to wash) and 'phobia' (fear). People with this condition experience intense anxiety about washing or bathing, which can significantly impact daily hygiene and quality of life.

Bufonophobia is the specific fear of toads. The name derives from 'Bufo', the genus that includes many toad species, combined with 'phobia'. People with this phobia experience intense anxiety or fear when encountering toads. Belonephobia is fear of pins, Batophobia is fear of heights, and Bacteriophobia is fear of bacteria.

Scolionophobia is the specific term for fear of school. Scatophobia relates to fecal matter, Scotophobia is fear of darkness, and Siderodromophobia is fear of trains/railroads.

Melanophobia is the fear of the color black (from Greek melanos meaning black/dark). Malaxophobia is fear of love play, Medomalacuphobia is fear of losing an erection, and Methyphobia is fear of alcohol.

Phasmophobia is the specific term for fear of ghosts (from Greek phasma meaning apparition/specter). Potophobia is fear of alcohol, Pocrescophobia is fear of losing weight, and Alliumphobia is fear of garlic.
