    Study Notes

    True/False Statements

    • Logical errors produce incorrect results despite valid syntax.
    • The Java Virtual Machine (JVM) executes Java byte code instructions.
    • Java statements terminate with a semicolon, not a colon.
    • Compiled byte code is distinct from source code.
    • Application software enhances computer usability for users.
    • Each byte in memory has a unique identifier known as an address.
    • Encapsulation combines data and code within a single object for protection.
    • Java source files use the .java extension, while compiled files use .class.
    • Procedures are sequences of statements performing specific tasks.
    • Solid-state drives (SSD) are faster than traditional disk drives and have no moving parts.
    • Computers serve various professional roles, resisting simple categorization.
    • Software is essential for computers to function, relying on programmers.
    • Variables can change values during program execution, contrary to some misconceptions.
    • Data hiding within objects protects against unauthorized access and corruption.

    Multiple Choice Insights

    • Procedural programming focuses on procedures, while object-oriented programming emphasizes object creation.
    • Random Access Memory (RAM) is volatile memory used for temporary storage.
    • The main programming methodologies today are procedural and object-oriented.
    • Validating program results ensures the original problem is addressed accurately.
    • Software encompasses all computer programs, distinct from hardware.
    • Objects provide outside access through methods, while hiding internal data.
    • Variables are symbolic names associated with memory locations in programs.
    • Hardware refers to the physical components of a computer system.
    • Data hiding allows only an object's methods to modify its data, enhancing safety.
    • Java byte code is universally compatible, making Java programs highly portable.
    • Pseudocode acts as a bridge between human languages and programming languages.
    • Byte code is interpreted by the JVM for execution based on the compiled code.

    Java Programming Essentials

    • Keywords in programming have specific, predefined meanings within the language.
    • Computers’ programmability enables them to perform a variety of tasks.
    • An object is a software unit that encapsulates both data and procedures.
    • Application software includes programs that enhance user productivity.
    • The end of a Java statement is denoted by a semicolon.
    • Syntax refers to the rules governing the structure of programming languages.
    • Procedures group statements to accomplish specific functions efficiently.
    • The CPU comprises the control unit and the arithmetic/logic unit (ALU).
    • A byte consists of 8 bits, the smallest addressable unit of digital information.
    • Runtime errors often stem from logical errors within the program.

    Computer Programming Fundamentals

    • A programming language is essential for writing computer programs.
    • Hardware represents the tangible parts of a computer system.
    • A computer program consists of instructions enabling problem-solving.
    • All components—CPU, input/output devices, memory—are crucial to a computer's operation.
    • Java's original name was Oak.
    • A program's sequence of instructions resides in the computer’s memory.
    • Byte code is executed and interpreted through the JVM.

    Development and Compilation
