Write a program in Java to enter any number from 1 to 9,999. Print whether the number is a single digit, two-digit, three-digit or four-digit number. 2. The charges for sending a parcel from Siliguri to Patna are as follows: Weight of the Parcel Charge(Rs.) upto 2 kgs Rs. 100 3-6 kgs Rs. 200 7-10 kgs Rs. 300 Above 10 kgs Rs. 400 Write a program to enter the weight of the parcel and print the total amount to be paid. 3. The standard form of a quadratic equation is given by ax2 + bx + c = 0 where a, b and c are the coefficients of x2 , x and the constant respectively. D= b2 4ac, where d is known as the discriminant. If d>=0, the roots are possible and If d<0, the roots are imaginary. The roots of the equation are determined by the formula x = -b b2 -4ac 2a Write a program in Java to determine the roots of the equation after taking a, b and c as input. 4. A library charges fines for books returned late as per the following criteria: No. of Days Late Fine(Rs Per Day) Upto 7 days Rs 1.50 Next 7 days Rs 2.50 Next 10 days Rs 3.50 Above 24 days Rs 5.50 Write a program in Java to enter the number of days the book is returned late and print the total fine to be paid by the borrower. 5. Write a program to enter any number from 1 to 12 and print the corresponding month of the year. Also print the number of days present in that particular month. (Use switchcase). 6. Write a menu driven program to print whether a number entered is Prime or Perfect as per the user s choice. 7. Write a program to input any 15 numbers (including positive and negative) and print the following: i. ii. iii. iv. v. vi. Number of positive integers Number of negative integers Sum of positive numbers Sum of negative number Average of the positive numbers Average of the negative numbers 8. A prime number is said to be Twisted Prime , if the new number obtained after reversing the digits is also a prime number. Write a program to accept a number and check whether the number is Twisted Prime or not. Sample Input:167 Sample Output:761 167 is a Twisted Prime . 9. Write a program to print all Pronic numbers from 1 to 1000. 10. Write a menu driven program to enter any number and print whether the number is a CYCLO number or TWIST number as per the user s choice. A CYCLO NUMBER is one in which the first and the last digit is the same. A TWIST NUMBER is one in which the first digit is odd and the last digit is even. Example : 7254 11. The International Standard Book Number (ISBN) is a unique numeric book identifier which is printed on every book. The ISBN is based upon a 10 digit code. The ISBN is legal if: 1 * digit1 + 2 * digit2 + 3 * digit3 + 4 * digit4 + 5 * digit5 + 6 * digit6 + 7 * digit7 + 8* digit8 + 9 * digit9 + 10 * digit10 is divisible by 11. Write a program in Java to : Input the ISBN code as a 10-digit number If the ISBN is not a 10-digit number, then output the message Illegal ISBN and terminate the program If the number is a 10-digit number then complete the sum as explained above and print whether the number is a Legal ISBN or Illegal ISBN . For example : 1401601499 is a legal ISBN. 12. Write a program in Java to check whether a given number is an AUTOMORPHIC number or not. An Automorphic number is one which is present in the last digits of its square. 252 = 625, which is an AUTOMORPHIC number. 52 = 25, which is an AUTOMORPHIC number. 13. Write a menu driven program to print the sum of the following series as per the user s choice. i. ii. S = 0+3+8+15+ ..99 S = 2-4+6-8 .+18-20 14. Write a menu driven program to print the sum of the following series as per the user s choice. i. ii. 1 2 3 9 S = 2 + 3 + 4 + 10 S = 2 + 15. Write a menu driven program to print the following patterns as per the user s choice. 1 1 1 2 3 3 1 2 3 1 2 3 4 1 2 3 4 5 5 5 5 7 7 7 7 9 9 9 9 9 16. A TECH NUMBER has even number of digits. If the number is split in two equal halves, then the square of the sum of these halves is equal to the number itself. Write a program to print and generate all four digit tech numbers. Example : 3025 Square of the sum of the sum of the halves of 3025 = (30+25)2 = (55)2 = 3025 is a tech number. 17. Write a program to ask the user to input any number and print the largest and the smallest digit present in the number. 18. Write a menu driven program in Java to enter any number and print whether the number is a NIVEN number or an ARMSTRONG number as per the user s choice. A NIVEN number is one which is exactly divisible by the sum of its digits. Example : 42 is a Niven number (42 is exactly divisible by 4+2) A number is said to be ARMSTRONG if the sum of cube of the digits of the number is equal to the number. Example : Input = 153 ( 13 + 53 + 33) Output = 153 is an ARMSTRONG number. 19. Write a program in Java to print whether the number is a SPECIAL TWO-DIGIT number or not. A special two-digit number is such that when the sum of the digits is added to the product of the digits the result is equal to the original number. Example: 19,59 20. A computerised bus charges fare from each of its passengers based on the distance travelled as per the tariff given below : Distance (in km) Charges First 5 km Rs 80 Next 10 km Rs 10/km More than 15 km Rs 8/km As the passenger enters the bus, the computer prompts Enter distance you intend to travel . On entering the distance, it prints his ticket and the control goes back for the next passenger. When there are no more passengers -1 is entered as the distance. At the end of the journey, the computer prints the following: The number of passengers travelling Total fare received Write a program to perform the above task.
