Syntax error in while loop

You have incorrectly capitalised While. It should be while (all lower-case).

See the documentation for while.

However, there are a number of other issues with your code.

Firstly, if you have tested that a number is not greater than or less than it must, by definition be equal. Therefore, you can change

else ( guess = r ) { 

to

else

This is fortunate for you as guess = r will not test for equality. Instead it will assign the value of r to guess. Also, because else (condition) is a syntax error.

Secondly You are trying to compare an int to a Random in this line:

if ( guess < r) // r is of type Random, guess is of type Int.

What you should actually do is use your Random to obtain an int, e.g.:

Random rnd = new Random();
int r = rnd.nextInt();

if (guess < r) // This is now valid.

Thirdly You have seeded your random number generator with 101. This means that it will always return the same sequence of numbers. This may be what you want but, if it is not, you can just use the paramaterless constructor to seed it with the current time in milliseconds

Random rnd = new Random();

else ( guess = r ) {

Change condition into comment.

else { // ( guess == r )

Do not capitalize the word "while". Case is very important in Java.

bunch of problems. See fix below.

1. Do not capitalize 'While'
2. if you do an else and want to check another condition, do an 'else if (...)'
3. you can't compare an int to a variable of type 'Random'. Instead save off Random.nextInt() and compare that

4. When comparing, make sure if you want 'is equal to' you use '==' not '='. The latter is the assignment operator, while '==' is the comparison operator.

    import java.util.Random;
   
    import java.util.Scanner;
   
    public class project2 {
    public static void main(final String[] args) {
   
       Scanner in = new Scanner(System.in);
   
       System.out.println("Welcome, I am thinking of a number between 1-100. Take a guess!");
   
       System.out.print("Please enter your number: ");
   
       int guess = in.nextInt();
   
       Random r = new Random(101);
       int actual = r.nextInt();
   
       int counter = 0;
   
       int totalcount = 6;
   
       while (counter != totalcount) { // being told to insert ";" and I have no clue why
   
           if (guess < actual) {
   
               System.out.print("You guessed " + guess);
   
               System.out.println("Too Low");
           }
   
           else if (guess > actual) {
   
               System.out.print("You guessed " + guess);
   
               System.out.println("Too High");
           }
   
           else if (guess == actual) {
   
               System.out.print("You guessed " + guess);
   
               System.out.println("YOU'RE PSYCHIC!");
   
           }
   
           counter++;
       }
   
   }
   

   }

guess = r is an assignment rather than a comparison. In this case the comparison is unnecessary as its the default case, but for future reference, guess == r is the correct way to do a comparison (assuming that guess is an int or other primitive)

Change

Random r = new Random(101);

to

Random random = new Random();
int r = random.nextInt(100) + 1;

You need an int to compare to the guess. You're using a Random which is a random number generator. The Random method nextInt(int i) returns a number between 0 (inclusive) and i exclusive.

Found three things

1) While incorrectly capitalized

2) r is the wrong type for comparison with integer, it's an instance of "Random"

3) you mean == and not =

I found all these errors by loading the program into Eclipse. I suggest you get a similar editor to help with these problems!

Hope this helps
