Java complete simple guess number game

Guess the number game v1.0 to achieve a custom range of game play, and in the game after the end of the next round, this is the other program does not take into account, I hope to help, and finally hope that someone is willing to help me solve the problem of code optimization, thank you.

/* Requirements:
* *. Complete a guess number game, the data range is customized by the player, the game starts after the player input values, give a narrow version of the guidance interval;
* *. After the end of the game, the player can choose whether to continue playing;
Ideas
* *. Creates a random number of the specified interval int, and the interval is specified by the player;
* *. For the player to guess the data, compared to give a judgment, big, small can give a guide interval, until guess right, record the number of guesses;
. After the game is over, ask the player whether to continue;
Steps
* *. Using scanner, the player creates the game range;
* *. The results are judged by using nested for in while, and a new guidance interval is given.
. After the game is over, prompt the player to enter the Yes string to continue the game;
*========= New ========= for optimization
* *. In the program, getting the random number part is duplicated, if there is a great God can write a getrandom to get the random number, and can continue to use min, max value is better;
* *. In a while loop, there should be a more concise way to determine if the input data is out of bounds.
*========= rookie begging for help =========
