Thread: :!! Unsure how to set this up/ Still learning java loops!!!!!

import java.util.Random;
 
 
public class RandomExample {
	public static void main(String[] args) throws FileNotFoundException{
		Random r = new Random();
 
		System.out.println(r.nextInt(42));
		System.out.println(r.nextInt(42));
	}
}

lmao, i just chopped out the body of some other code, didn't pay attention to that

And i was simply showing a different way to do random numbers

Chris

try this one... i hope this might help you a little bit..

this is a simple program that looks similar to what you want..

public class LoopSample9 {
 
    public static void main(String[] args) {
 
        int targetNumber,
            guessNumber;
 
        //boolean variable to determine if the loop should end
        boolean loopEnd = false;
 
        /**
         * GENERATES THE TARGET NUMBER
         * This one is generated by Math.floor( )
         * Because the operation Math.random( ) * 10; has the range of
         * 0.92839 - 9.83928398
         *
         * So we have to add the method Math.floor to return the
         * LARGEST whole numbers that is LESS than or EQUAL to the
         * generated random number. so the range will be still 0.923823 to 9.29839283
         *
         * Now we have to add + 1 to the operation Math.random ( ) * 10 + 1; to
         * extend the range of the
         * generated random number from 1.88738273 to 10.98293829
         * So the range will now be 1.9887238723 - 10.92832983.
         *
         * Now if we add the method Math.floor( ),
         * that is Math.floor(Math.random * 10) + 1;
         * any random decimal number that will
         * be generated by the Math.random( ) * 10 + 1;
         * (e.g. 1.382983) or (e.g. 10.29839)
         * will return the LARGEST whole number LESS than or EQUAL to
         * that generated number(i.e. 1.0) or (i.e. 10.0)
         */
 
         //to avoid the number "0" (zero)
        targetNumber = (int) (Math.floor(Math.random() * 10) + 1); 
        System.out.println("Our Target Number Is: " + targetNumber);
        System.out.println("\n");
 
        //infinite loop begins here...
        while (true) {
 
            /**
             * GENERATES THE GUESS NUMBER
             * This is generated by Math.ceil( )
             * This is slightly different from the operation and methods that
             * generates the targetNumber
             *
             * Here, we now use the method Math.ceil, and as you can see we dont add + 1;
             *
             * Heres why..
 
             * The operation Math.random( ) * 10; only generates a random number
             * ranging from 0.29382938759 - 9.9829832983 (we already discuss it
             * from the previews comments)
             *
             * So if we add the method Math.ceil( ) in this operation, that will be
             * Math.ceil(Math.random( ) * 10;
             * This operation will return a value of
             * the Smallest number Greater than or equal to
             * the generated random number (e.g. 0.982983) or (e.g. 9.823839)
             * that will be (1.0 to 10.0)
             *
             * Its because the method Math.ceil( ) returns a value which is the Smallest Number
             * GREATER than or EQUAL to that number .
             *
             * In this operation, if we add + 1 to the opetaion Math.ceil(Math.random * 10) + 1;
             * it will generate a random number ranging from 1.2398983 to 10.2872873
             * and by using the Math.ceil method it will return the value of
             * the SMALLEST whole number
             * GREATER than or EQAUL to that number (e.g 10.982398)
             * it will return a number (i.e. 11.0)
             *
             * So we dont have to add + 1, or we dont have to
             * extend the range of the Math.random( ) * 10;
             *
             * NOTE: Because by adding or using Math.ceil( ) method it
             * will generate a random whole number
             * ranging from 1 - 11;
