Question
Use Java please
How can I implement a console selection menu that prompts a user to select between playing (7 guesses) or (User guesses)? My code for 7 guesses and User guesses is in the photos (I don't need help with those, just the console selection menu).

Transcribed Image Text:(User Guessing Game)
```java
Scanner sc = new Scanner(System.in);
int num, guess, tries = 0;
int max = 100, min = 1;
num = (int)(Math.floor(Math.random() * (max - min + 1) + min));
System.out.println("Guess My Number Game");
System.out.println("--------------------");
do {
System.out.println("Enter a guess between 1 and 100 : ");
while(true) {
try {
guess = Integer.parseInt(sc.next());
if(guess > 0 && guess <= 100)
break;
else System.out.println("Please enter a number in the range 1-100");
} catch(NumberFormatException ex) {
System.out.println("Please enter a number");
}
}
tries++;
if (guess > num) {
System.out.println("Too high!");
} else if (guess < num) {
System.out.println("Too low!");
} else {
System.out.println("\nCorrect! You got it in " + tries + " guesses!");
}
} while (guess != num);
```
**Explanation:**
This Java code is a simple "Guess My Number" game. The program randomly selects a number between 1 and 100, and the user has to guess what it is. Here’s how it works:
1. **Initialization:**
- A scanner object (`sc`) is created to read user input.
- Variables for `num` (the number to guess), `guess` (the user’s guess), and `tries` (the count of attempts) are initialized.
2. **Random Number Generation:**
- The target number (`num`) is generated randomly between 1 and 100 using `Math.random()`.
3. **Gameplay:**
- The game runs inside a `do-while` loop, prompting the user to enter a guess.
- A nested `while` loop ensures the user inputs a valid number in the range 1 to 100.
- If the input is not a valid number, it prompts the user again.
4. **Guess Checking:**
- Each guess increments the `tries` counter.
- If the guess is too high or too low, the program provides feedback.
- When the guess is correct, the program congratulates the user and displays the number of attempts made.
5. **Loop

### Guess My Number Game - Java Program
This Java program demonstrates a simple "Guess My Number" game using a binary search approach. The aim is for the computer to guess a number chosen by the user. Follow the description and code comments to understand how the program works.
```java
(7 Guesses)
Scanner sc = new Scanner(System.in);
int num, guess, tries = 0;
int max = 100, min = 1;
System.out.println("Enter a number between 1 and 100 you want the computer to guess:");
while(true){
try {
num = Integer.parseInt(sc.next());
if(num > 0 && num <= 100)
break;
else System.out.println("Please enter a number in the range 1-100");
} catch (NumberFormatException ex) {
System.out.println("Please enter a number");
}
}
System.out.println("Guess My Number Game");
System.out.println("--------------------------");
do {
guess = (min + max) / 2;
System.out.println("Computer guessed " + guess);
tries++;
if (guess > num) {
System.out.println("Too high!");
max = guess;
} else if (guess < num) {
System.out.println("Too low!");
min = guess + 1;
} else {
System.out.println("\nCorrect! You got it in " + tries + " guesses!");
}
} while (guess != num);
```
### Explanation
- **User Input:** The user is prompted to enter a number between 1 and 100.
- **Input Validation:** The program checks whether the input is within the specified range (1-100). If not, it prompts the user again.
- **Binary Search Approach:**
- The program uses a binary search technique to guess the user’s number:
- It starts by guessing the midpoint of the current range.
- If the guess is too high, it adjusts the maximum boundary.
- If too low, it adjusts the minimum boundary.
- This continues until the computer guesses the correct number.
- **Tries Count:** The program keeps track of the number of guesses the computer makes until it arrives at the correct number.
### Educational Value
This program teaches:
- Basic input and output in Java.
- Exception handling for user input
