Write a number guessing game, from 1 to 188, and let the user input the number on the console. If the user guesses a higher number, it will prompt the higher number, and if it is smaller, it will prompt the smaller number.
Prompt word: Randomly generate a number between 1 and 188
Prompt word: write a mark, default false
Tip: Create a Scanner object
Prompt word: In the loop, the loop condition is that the flag is true to terminate the loop. The user is first prompted to guess the number. The user enters the number and determines whether the value of guessNumber is the same as number. If they are the same, set the flag to true. Jump out of the loop; determine guessNumber. Is the value the same as number? If it is larger, it will indicate that it is too large. If it is small, it will indicate that it is too small.
Prompt word: Finally generated prompt: Congratulations, you guessed it right
