Write a method that uses the above algorithm to generate a random integer of a specified number (for example, three).

//A,c,m is constant

R = (R * A + C)% m

Modulus=231-1=int. MaxValue

multiplier=75=16807

C=0

It is possible to repeat after the number of 231-2 has been displayed.

public class Suiji {

/**

* @param args

*/

public static void Main (string[] args) {

TODO auto-generated Method Stub

Long a=123;

Long c=321;

Long m=456;

for (int i=0;i<1000;i++)

System.out.println (rand (I, A, C, M));

}

public static long rand (long R,long a,long c,long m)

{

R = (R * A + C)% m;

return R;

}

}

Look at the following code, do you find anything special?

Methodoverload.java

Using Overloaded Methods

public class Methodoverload {

public static void Main (string[] args) {

System.out.println ("The square of the integer 7 is" + Square (7));

System.out.println ("\nthe square of double 7.5 is" + square (7.5));

}

public static int square (int x) {

return x * x;

}

public static double square (double y) {

return y * y;

}

}

I find that functions of the same name can be different, and different parameter types can automatically invoke the corresponding function (method), that is, the overload of the method.

Two or more methods that meet the following conditions form an "overloaded" relationship:

(1) The method name is the same;

(2) The parameter types are different, the number of parameters is different, or the order of the parameter types is different.

Note: The return value of the method is not used as a criterion for method overloading.

Write a method that uses the above algorithm to generate a random integer of a specified number (for example, 1000).
