Java – random number generator

I need to write a program in Java to generate random numbers within the range of [0,1] using the following formula:

Suppose a, B and amp; Any fixed int value of M and x0 = 0.5 (i.e. I = 0)

What should I do?

I've tried this, but it's obviously wrong:

int a = 25173,b = 13849,m = 32768;
double X_[i];
for (int i = 1; i<100; i++)
   X_[i] = (a*(X_[i]-1) + b) % m;
double X_[0] = 0.5;
double double = new double();
System.out.println [new double];

Solution

Here are some tips:

int a,d,m,x;

Multiplication is *, mod is%

to update

OK, I'll give you another hint You only need an X, you don't need all these arrays; Because you only use integers, you don't need any floats or double arrows

The important lines of code are

x = (a * x + b) % m ;

You don't need another x, because = x on the right is old X or XI-1; The one on the left will be your "new" X or Xi

Now, from there, you need to write a Java wrapper that lets you create a method, which means writing a class
