Assignment on Method4
[Non-void Method with Parameters]
1. Write a Java program using a method called long square(int n) to find the Square of any number.
2. Write a Java program using a method called long product(int n1, int n2) and double average(float n1, float n2) to find the Product and Average of two numbers.
3. Write a Java program using a method called int area(int l int b), int perimeter(int l int b) to find the Area and Perimeter of Rectangle.
4. Write a Java program using a method called float simpleInterest(float p, float r, float t) to find the Simple Interest.
5. Write a Java program using a method called long factorial(int n) and int sumOfSeries(int n) to print the Factorial /Sum of Series S=1+2+3+.... +n.
6. Write a Java program using a method called int greatestDigit(int n), int smallestDigit(int n) to accept a number from user and find the greatest and smallest digit.
7. Write a Java program using a method called boolean specialTwoDigit(int n) to find the special two-digit number is such that when the sum of the digits is added to the product of its digits, the result is equal to the original two-digit number.
Example:
Consider the number 59.
Sum of digits = 5+9=14
Product of its digits = 5 x 9 = 45
Sum of the digits and product of digits = 14 + 45 = 59
8. Write a Java program using a method called int dudeney(int n) to check whether the number is a Dudeney number, a number is Dudeney if the cube of the sum of the digits is equal to the number itself.
Eg : 512
=(5+1+2)3 = (8)3 =512
9. Write a Java program using a method called boolean markNumber(int n) to check whether the number is a Mark number or not. A number is said to be Mark when sum of the squares of each digit is an even number as well as the last digit of the sum and the last digit of the number given is same.
Example: n = 246
sum = 2 x 2 + 4 x 4 + 6 x 6 = 56
56 is an even number as well as last digit is 6 for both sum as well as the number.
10. Write a Java program using a method called char palindrome(int n) to print the number is Palindrome or Not.
