# Java Program to Guess a Random Number in a Range

• Last Updated : 04 Dec, 2020

Write a program that generates a random number and asks the user to guess what the number is. If the user’s guess is higher than the random number, the program should display Too high, try again. If the user’s guess is lower than the random number, the program should display Too low, try again. The program should use a loop that repeats until the user correctly guesses the random number.

```Input: 15 (a random value that is not known before)
Output: Guess a number between 1 and 100:
1
Too low, try again
Guess a number between 1 and 100:
10
Too low, try again
Guess a number between 1 and 100:
25
Too high, try again
Guess a number between 1 and 100:
20
Too high, try again
Guess a number between 1 and 100:
15
Yes, you guessed the number.```
