AP Computer Science Exam Question:

Which of the following statements correctly match the primitive data types with their corresponding names and keyword representations in Java?

A)

1. byte - Integer - int
2. short - Real - double
3. int - Character - char
4. long - Boolean - boolean

B)

1. byte - Integer - int
2. short - Real - float
3. int - Character - char
4. long - Boolean - bool

C)

1. byte - Integer - byte
2. short - Real - short
3. int - Character - char
4. long - Boolean - bool

D)

1. byte - Integer - byte
2. short - Real - double
3. int - Character - int
4. long - Boolean - boolean

Choose the correct option from A, B, C, or D.

Answer:

The correct option is A)

• byte is an integer type that can represent whole numbers from -128 to 127.
• short is an integer type that can represent whole numbers from -32,768 to 32,767.
• int is an integer type that can represent whole numbers from -2,147,483,648 to 2,147,483,647.
• long is an integer type that can represent whole numbers from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807.

The correct keyword representations for the given primitive data types in Java are:

• byte: byte
• short: short
• int: int
• long: long

Therefore, option A) 1. byte - Integer - int, 2. short - Real - double, 3. int - Character - char, 4. long - Boolean - boolean is correct.
