Pseudo Random Number Generator in Java

This is java program to generate a random numbers, using linear congruential generator. The formula for next random number in the sequence is x(n+1) = {a*x(n)+c}mod m, where x(n+1) is current number to generate, x(n) is previously generated, a is multiplier, c is additive term and m is modulus.

Here is the source code of the Java Program to Implement the linear congruential generator for Pseudo Random Number Generation. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

//This is a sample program to generate random numbers based on linear congruential generator

```
import java.math.BigInteger;
```
```
import java.util.Random;
```
```
 
```

public class Linear_Congruential_Random_Numbers

```
{
```

    public static void main(String args[])

```
    {
```

        BigInteger n = new BigInteger(16, new Random(){});

```
        Random rand = new Random();
```

        BigInteger m = new BigInteger("65535");//2^16

```
 
```
```
        for(int i=0; i<5; i++)
```
```
        {
```
```
            System.out.print(n+", ");
```

            BigInteger a = new BigInteger(16, new Random(){});

            BigInteger c = new BigInteger(16, new Random(){});

            n = ((a.multiply(a)).add(c)).mod(m);

```
        }
```
```
        System.out.println("... ");
```
```
    }
```
```
}
```

Output:

$ javac Linear_Congruential_Random_Numbers.java
$ java Linear_Congruential_Random_Numbers
5107, 48257, 43654, 50875, 12815, ...
