2. A stack can be used to print numbers in other bases (multibase output). Examples: a) (Bases) 2810 = 3 * 8¹ + 4* 8º = 348 b) (Base 4) 7210 = 1* 4³ + 0* 4² + 2 * 4¹ + 0* 4 = 10204 c) (Base 2) 5310 = 1* 25 + 1*24 + 0*2³ +1* 2² +0* 2¹ + 1* 2⁰ = 110101₂ Write a java program using stacks that takes 3 non-negative (base 10) long integer numbers and a base B (B is in the range 2-9) and writes the number to the screen as a base B number. The program prompts the user for 3 numbers and bases, and then outputs them. Use as input: a) 7210 b) 5310 c) 355310 Base 4 Base 2 Base 8

Question

The first image is the main question, the second image is the directions for the program. The program has to be written in Java.

### Using Stacks to Print Numbers in Various Bases Stacks can be used to print numbers in other bases (multibase output). Here are some examples to demonstrate this concept: #### Examples: **a) (Base<sub>8</sub>)** \[ 28_{10} = 3 \times 8^1 + 4 \times 8^0 = 34_{8} \] **b) (Base<sub>4</sub>)** \[ 72_{10} = 1 \times 4^3 + 0 \times 4^2 + 2 \times 4^1 + 0 \times 4^0 = 1020_{4} \] **c) (Base<sub>2</sub>)** \[ 53_{10} = 1 \times 2^5 + 1 \times 2^4 + 0 \times 2^3 + 1 \times 2^2 + 0 \times 2^1 + 1 \times 2^0 = 110101_{2} \] #### Task: Write a Java program using stacks that takes 3 non-negative (base 10) long integer numbers and a base B (where B is in the range 2-9), and converts each number to its representation in base B. The program should prompt the user to input the numbers and the desired bases, then output the converted numbers. #### Input Examples: 1. \( 72_{10} \) in Base 4 2. \( 53_{10} \) in Base 2 3. \( 355_{10} \) in Base 8 By following these examples and using the provided task description, you can create a versatile program to convert decimal numbers into various bases.

--- ## Program #2 1. **Show the `ListStackADT<T>` Interface** 2. **Create a `ListStackDataStrucClass<T>` with the following methods:** - Default constructor - Overloaded constructor - Copy constructor - `getTop` - `setTop` - `isEmpty` - `ifEmpty` (if empty throw the exception) - `push` - `peek` - `pop` - `toString` 3. **Create a private inner class of `ListStack<T>` called `StackNode<T>` with the following methods:** - Default constructor - Overloaded constructor - Copy constructor - `getValue` - `getNext` - `setValue` - `setNext` 4. **Create a `BaseConverter` class (non-generic) with the following methods:** - Default constructor - `inputPrompt` - `convert` [converts a `BaseNumber` to a converted `String`] - `convertAll` [instantiate a `String` object] - `toString` - `processAndPrint` 5. **Create a private inner class `BaseNumber`. The inner class has the following methods:** - Default constructor - Overloaded constructor - `getNumber` - `getBase` - `setNumber` - `setBase` *Note: Make your private instance variables in the inner class `Long` type.* 6. **Create a `BaseConverterDemo` class that only has 2 statements:** - Create a `BaseConverter` object - Have it invoke `processAndPrint` 7. **Exception classes: `StackException`, `EmptyStackException`, `FullStackException`** ---
