Java Program To Generate Random Numbers

Code:

import java.util.Random;

public class Rand_no 

{

public static void main(String[] args)

{

Random r=new Random();

int rand_nmbr1=r.nextInt();                     // gives random no. uptil integer range

  int rand_nmbr2=r.nextInt(100);               // 0 to 99

  double rand_nmbr3=r.nextDouble();       //gives random no. uptil the range of double

                     
  System.out.println("Integers Random number1 is = "+rand_nmbr1);

  System.out.println("0 To 99 Random number2 is = "+rand_nmbr2);

  System.out.println("Doubles Random number3 is = "+rand_nmbr3);

// if u want to generate 1 to 100 then

int n=r.nextInt(100)+1; // 1 to 100

System.out.println("Random number Betweem 1-100 is = "+n);

//A random number between 4 and 17 inclusive?

int ran = r.nextInt(14) + 4;

System.out.println("Random number between 4-17 = "+ran);

int n2=r.nextInt(7)+4;// Arbitrary Range or 4-10

System.out.println("Random number(4 to 7) Arbitrary range is = "+n2);

//A random number between 50 and 100 inclusive?

int n3=r.nextInt(51)+50;

System.out.println("Random number 50-100 = "+n3);

}

}
