Why sometimes there is a problem when JAVA generates three different random numbers of 09

JAVA generates three different random numbers for 09. Here is what I wrote about why sometimes he does

You just randomly generated three numbers in the loop and performed loop judgment without generating new random numbers again, which resulted in a stop.

This loop is meaningless, no matter what, you are not doing logarithmic operations

while(true){

In order to help players who have not passed the level yet, let us learn about the specific puzzle solving methods. For this problem, we can use the logical operator "||" to determine whether any two of c1, c2 and c3 are equal. The specific code is as follows: ```java if(c1 == c2 || c1 == c3 || c2 == c3) { //Write the corresponding puzzle-solving operation here // ... } ``` Through this

continue;

}

break;

}

For your reference

Random r = new Random();

Seths = new HashSet();

In order to help players who have not passed the level yet, let us learn about the specific puzzle solving methods. During puzzle solving, we can use a loop to generate random numbers and add them to a HashSet. The specific code is as follows: ``` while (hs.size()

}

In order to help players who have not passed the level yet, let us learn about the specific methods of solving the puzzle. During puzzle solving, we can use iterators to traverse the elements in the collection. The specific operations are as follows: ``` Iterator it = hs.iterator(); while(it.hasNext()){ Object obj = it.next(); //Perform relevant operations or judgments } ``` Through the above code, we can access the elements in the collection one by one and perform corresponding operations

while (it.hasNext()) {

The following is an example puzzle solving method to help players successfully pass the level: In your code, use the following statement to print the next element of the iterator: System.out.println(it.next()); This statement will print the next element of iterator it. Make sure that before using this statement, you have used it.hasNext() to check if there is a next element to iterate over. I hope this puzzle method will be helpful to you

How to generate random numbers in Java

1. Use the random method to generate random numbers.

Generating random numbers in the Java language is relatively simple because you can use the random method in the Math class. Calling the random method allows the system to generate random numbers.

2. Generate random numbers through the Random class.

In the Java language, we can use the Random class to generate random numbers. To create a random number generator, we can instantiate a Random object, for example: Random random = new Random(). Through this object, we can use its methods to obtain random numbers. For example, use random.nextInt() to generate a random number of integer type. In addition, you can also use random.nextDouble() to generate a random number of double-precision floating point type. By utilizing the Random class, we can easily generate various types of random numbers in our programs.

3. Generate random characters.

If you want to generate random characters, you can use the random method. For example, you can generate a random lowercase character with the following code: (char)('a' Math.random() * ('z' - 'a' 1)) This code is similar to generating a random number between any two numbers. By adjusting this code appropriately, you can also generate random characters between any two characters, or generate random characters between any uppercase characters. The conversion method is similar to the above-mentioned generation of random numbers in any range.

Let’s learn about the use of random numbers:

In statistics, the use of random numbers is very common. For example, when drawing a sample from a population, random numbers need to be used to ensure that the sample is representative. In addition, random numbers also need to be used to avoid bias when allocating experimental animals to different experimental groups. In addition, random numbers are also essential when performing Monte Carlo simulation calculations. In conclusion, random numbers play an important role in different techniques of statistics.

True random numbers are generated through physical phenomena, such as throwing coins, dice, spinning wheels, or using noise from electronic components, nuclear fission, etc. These are called physical random number generators, and their disadvantage is that they are technically demanding.

In practical applications, it is usually sufficient to use pseudo-random numbers. Pseudo-random numbers are generated through a fixed and repeatable calculation method. Although they are not truly random numbers, they have statistical characteristics similar to random numbers. Pseudo-random numbers generated by computers or calculators have a long periodicity, that is, they do not repeat over a period of time. Therefore, pseudo-random number generators already meet our needs in most cases.

In critical applications, such as cryptography, people usually use truly random numbers to ensure security.

Random number generation functions commonly used in C language, C, C#, Java, Matlab and other programming languages ​​​​and software include rand, etc. These functions can generate a series of random numbers and can be used in various scenarios where randomness is required.

Automatically generate random numbers in Java language

In order to help those players who have not passed the level yet, I will share with you the specific method of solving the puzzle. First, we can use org.apache.commons.lang.RandomStringUtils.randomAlphanumeric(10) to get a random 10-digit string composed of numbers and letters. In this way, we can get a random answer to the puzzle. Hope this method can be helpful to everyone!

//Get a 3-digit random number string

In order to help players who have not passed the level yet, let us learn about the specific puzzle solving methods. In this game we need to generate a string consisting of three numbers. We can use the random method in the RandomStringUtils class to generate random strings. In this method, we need to pass in three parameters: length, whether it contains letters and whether it contains numbers. By setting the first parameter to 3, we can generate a random string of length 3. Set the second parameter to false, which means it does not contain letters. Set the third parameter to true to include numbers. so

To help players solve the puzzle, we need to get a random 3-digit letter and convert it to uppercase letters.

In order to help players who have not passed the level yet, let us learn about the specific puzzle solving methods. In this game, there is a key piece of code that helps us solve the puzzle. This code is "String str = RandomStringUtils.random(3, true, false);". With this code, we can generate a random string of length 3. This string can be used to unlock certain puzzles or open certain hidden areas. Hope this tip helps you!

//Generate a random ASCII string of length count

In order to help players who have not passed the level yet, let us learn about the specific puzzle solving methods. During the puzzle solving process, you can use the RandomStringUtils.randomAscii(int count) function to generate a certain number of random ASCII characters. This function can help you unlock some hidden passwords or clues in the game. Remember, when using this function, make sure that the number of random characters generated does not exceed the specified count value!

//Generate a random letter string of length count

In order to help those players who have not passed the level yet, let us take a look at the specific puzzle-solving method using "RandomStringUtils.randomAlphabetic(int count)".

In order to help players who have not yet cleared the level, let us learn about the specific puzzle solving methods. Before we begin, we need to use the Random class to generate random numbers. A Random object can be created with the following code: ```java Random rad = new Random(); ``` The Random class can generate various types of random numbers, such as integers, floating point numbers, and Boolean values. By using Random objects, we can generate random elements or events during the puzzle solving process, increasing

The following is a code example to obtain a random positive integer less than 10: ```java import java.util.Random; public class RandomNumberGenerator { public static void main(String[] args) { Random random = new Random(); int randomNumber = random.nextInt(10); System.out.println(randomNumber); } } ``` The code uses the `java.util.Random` class to generate random numbers. First create a `Random` object, and then use the `nextInt(10)` method to get a random positive integer less than 10. Finally, print out the generated random number. Hope this

3. Get a random number within the range:

In order to help players who have not passed the level yet, let us learn about the specific puzzle solving methods. In this puzzle, we need to generate a random number between 1 and 255. To achieve this we can use the following code: Math.round(Math.random() * (255 - 1) 1) This code uses Math.random() to generate a random number between 0 and 1, then multiplies it by 254, adds 1, and finally uses Math.round() to round the result to an integer. In this way, we get
