• Subtraction: Subtracts the second number from the first.
• Multiplication: Multiplies two numbers.
• Division: Divides the first number by the second.
• Modulo: Computes the remainder of dividing the first number by the second.
• Store: Stores the last result in memory.
• Retrieve: Retrieves the stored value.
• Clear: Clears the stored value.
• Exit: Exits the calculator.

Requirements

• Java Development Kit (JDK) 8 or higher

  multiply 3 3

  Output: Result: 9.0

• Divide: Divides the first number by the second.

  divide 10 2

  Output: Result: 5.0

• Modulo: Computes the remainder of dividing the first number by the second.

  modulo 7 2

  Output: Result: 1.0

• Store: Stores the last result in memory.

  store

  Output: Stored value: 5.0

• Retrieve: Retrieves the stored value.
