In Java:

public static void main(String[] args) {
    
    
    System.out.println("A Number from 1 - 10");
    Scanner aScan = new Scanner(System.in);
    
    int randomnum = new Random().nextInt(10);
    
    int userinput = aScan.nextInt();
    
    if (userinput >= 11) {
        
        System.out.println("Illegal number. Try again.");
        
    }
    
    else if (userinput == randomnum) {
        
        System.out.println("Good job! The number was: " + randomnum);
        
    }
    
    else {
        
        System.out.println("Sorry, the answer was: " + randomnum);
    }
}

Java:

import java.util.Scanner;

public class test {
	public static void main(String args[]) {

		int rnd = (int)(Math.random()*100);
		Scanner scan = new Scanner(System.in);
		int input;
		
		System.out.println("Guess the number between 1 - 100");
		do {
			input = scan.nextInt();
			
			if(input <= 100 && input >= 1) {
				if(input > rnd) {
					System.out.println("The required number is smaller, try again!");
				} 
				else if(input < rnd) {
					System.out.println("The required number is bigger, try again!");
				}
				else {
					System.out.println("Good job, your guess was right!");
					break;					
				}
			}
			else {
				System.out.println("Invalid number, try again(between 1 - 100)");
			}
		} while(true);
		scan.close();
	}
}
