 Q.Write a program that generates a random number and asks the user to guess what the number is. If the user's guess is higher than the random number, the program should display "Too high, try again." If the user's guess is lower than the random number, the program should display "Too low, try again." The program should use a loop that repeats until the user correctly guesses the random number.

Let us first see our roti class. public class roti {     int hour, minute, second;          public roti() {         setTime(0,0,0);     }     public roti(int h) {         setTime(h,0,0);     }     public roti(int h, int m) {         setTime(h,m,0);     }          public roti(int h, int m, int s) {         setTime(h,m,s);     }          public void setTime(int h, int m , int s) {         setHour(h);         setMinute(m);         setSecond(s);     }          public void setHour(int h) {         hour = ((h>=0 &...

Whenever we are using the constructor to initalise the value without using any method we need to use toString method to print the value of the parametes. In this example we shall see what will happen if we don't use  toString() and then when we use it. A. Without toString() CODE OF ROTI CLASS public class roti {      private int age;      private String name;           roti (int age, String name){          this.age = age;          this.name= name;      } } CODE OF SABZI CLASS public class sabzi {          public static void main (String args[]) {                     roti rotiObject = new roti(4, "Dheeraj"); System.out.println(rotiObject);         } } OUTPUT WHEN USING toString public class roti {  ...
