Round 1

Primitive Types

$200
This character represents a single 16-bit Unicode unit.
$400
This is the result of casting the double 3.9 to an integer.
$600
This numeric data type uses 32 bits to store whole numbers.
$800
This boolean value represents the default state of a boolean class variable.
$1000
This keyword declares a variable that cannot be changed after initialization.

Using Objects

$200
This keyword is used to create a new instance of a class.
$400
This method is used to compare the content of two String objects.
$600
This class is often used to generate random numeric values.
$800
This term refers to the method that initializes a newly created object.
$1000
This type of method does not return any value to the caller.

Boolean Logic

$200
This logical operator returns true only if both operands are true.
$400
These are the two possible states for a relational comparison.
$600
This operator performs a logical NOT operation.
$800
This describes the condition where logical operators are evaluated based on precedence.
$1000
This programming principle states that the second operand of a logical operation is skipped if the result is already determined.

Iteration

$200
This loop guarantees the block of code executes at least once.
$400
This keyword terminates the current loop immediately.
$600
This is the control variable used to track the number of times a block has repeated.
$800
This loop structure is typically used when the number of iterations is known.
$1000
Unlike its posttest counterpart, this loop structure checks its condition before every iteration.

Classes

$200
This keyword is used to access members of the current object instance.
$400
This access modifier restricts visibility to the same class.
$600
These methods provide read-only access to private fields.
$800
This concept allows multiple methods to share the same name with different parameters.
$1000
This modifier allows a method or variable to be accessed globally without an object instance.

Arrays

$200
This is the starting index for all array-based data structures in Java.
$400
This is the integer representing the number of elements in an array.
$600
This error occurs when accessing an index outside the valid bounds of an array.
$800
This process involves organizing array elements in ascending or descending order.
$1000
This type of loop is specifically designed to traverse arrays without using an index.

Double Jeopardy

Primitive Types

$400
This is the standard size in bytes of a short integer.
$800
This 64-bit primitive type is used for high-precision decimal numbers.
$1200
This arithmetic operation computes the remainder of a division.
$1600
This keyword is used to explicitly convert one numeric type to another.
$2000
This represents the maximum value for a 32-bit signed integer.

Using Objects

$400
This string method returns a portion of the original text.
$800
This object-oriented concept wraps data and methods into a single unit.
$1200
This keyword signifies that an object variable refers to no memory address.
$1600
This method converts an object representation into a readable string.
$2000
This class provides static methods for calculating powers and square roots.

Boolean Logic

$400
This term refers to the boolean result of an if-statement conditional.
$800
This expression evaluates to true if either operand is true.
$1200
This structure is used to handle multiple conditional paths based on a single variable.
$1600
This condition occurs when variables are compared using reference equality rather than content equality.
$2000
This rule, named after a famous mathematician, simplifies complex boolean expressions involving NOT and AND/OR.

Iteration

$400
This term describes a loop placed inside the body of another loop.
$800
This variable type is used to maintain a running total within a loop.
$1200
This keyword is used to skip the current iteration and move to the next in a loop.
$1600
This common error happens when a loop fails to reach its end condition.
$2000
This programming approach solves problems by calling the same method from within itself.

Classes

$400
This is the superclass of all classes in the Java hierarchy.
$800
This keyword invokes a constructor or accessible member from a superclass.
$1200
This method signature defines a replacement of an inherited method in a subclass.
$1600
This design principle dictates that a subclass should be interchangeable with its superclass.
$2000
This keyword establishes an inheritance relationship between two classes.

Arrays

$400
This method adds an element to the end of a dynamic list.
$800
This list-based class allows for dynamic resizing of stored elements.
$1200
This structure is used to store data in a grid-like fashion using rows and columns.
$1600
This algorithm shifts elements to sort an array by repeatedly swapping adjacent items.
$2000
This search algorithm efficiently finds elements in a sorted array by repeatedly dividing the search interval.
