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.

Final Jeopardy · Computer Science Concepts

This term refers to the process of verifying that software meets specified requirements and is free of defects.
