    	{
    	GuessWhat example= new GuessWhat();
    	example.getRandomNumber();
    	}
     
     
        public static void getRandomNumber();
        {
        int min=50;
        int max=100;
        Random randGenerator= new Random();
        int randomNum=randGenerator.nextInt(max-min+1)+ min;
        System.out.println("Random number generated is:" + randomNum);
        }
    								//everything up to this is correct-ask user for guess//
    	Scanner input=new Scanner(System.in);
    	System.out.println (" Please enter another number within the range of fifty through hundred. ");
    	int guess2=input.nextInt();
    	System.out.println (" Please enter a last number within the range of fifty through hundred. ");
        int guess3=input.nextInt();
     
    									// to show which one is higher //
     
    	int guess;
    	int NumberOfGuesses;
     
    	NumberOfGuesses=0;
    	guess=0;
    	while(guess!=randomNum && NumberOfGuesses<3)
    	{
    	int guess1=input.nextInt();

    Default Re: GuessWhat- same errors repeated 4 times?

    public static void getRandomNumber[B]();[/B]
    {
    int min=50;
    int max=100;
    Random randGenerator= new Random();
    int randomNum=randGenerator.nextInt(max-min+1)+ min;
    System.out.println("Random number generated is:" + randomNum);
    }

    methods dont end in semicolons

    and i am assuming for your purposes you shouldnt be using Static here.

    you have an extra { at the top.

    you have lots of code outside of a method.

    Partial correction, it compiles now but not sure if it does what you expect it too

    import java.util.Scanner;
    import java.util.Random;
    public class GuessWhat
    {
    public static void main (String[] args)
    {
    //it isn't necessary to create an object of example to run getRandomNumber...since that method is within the class of this method itself.
    getRandomNumber();
    }
     
     
    public static void getRandomNumber()
    {
    int min=50;
    int max=100;
    Random randGenerator= new Random();
    int randomNum=randGenerator.nextInt(max-min+1)+ min;
    System.out.println("Random number generated is:" + randomNum);
     
    //everything up to this is correct-ask user for guess//
    Scanner input=new Scanner(System.in);
    System.out.println (" Please enter another number within the range of fifty through hundred. ");
    int guess2=input.nextInt();
    System.out.println (" Please enter a last number within the range of fifty through hundred. ");
    int guess3=input.nextInt();
     
    // to show which one is higher //
     
    int guess;
    int NumberOfGuesses;
     
    NumberOfGuesses=0;
    guess=0;
    while(guess!=randomNum && NumberOfGuesses<3)
    {
    int guess1=input.nextInt();
    System.out.println (" Please enter a number within the range of fifty through hundred. ");
    if(NumberOfGuesses<6)
    {
    if(randomNum>guess)
    {
    System.out.println (" Guess is too low. Try a higher number." );
    }
    System.out.println (" Please enter another number within the range of fifty through hundred. ");
    guess2=input.nextInt();
    if(randomNum<guess)
    {
    System.out.println (" Guess is too high. Try a lower number. ");
    }
    System.out.println (" Please enter another number within the range of fifty through hundred. ");
    guess3=input.nextInt();
     
    }
     
    }
    }
    }
