Simplified Fraction - Sum of an array - Command Line Argument - Print String

 Simplified Fraction

 

St. Patrick Convent organizes a project exhibition "Innovative Minds" every year with an objective to provide the platform and unleash the potential of the students by showcasing their innovative projects. Pasha is a smart high school student and was eager to participate in the fair for the first time.
 
After a lot of ground works, she decided her project and set out to design the same. Her project requirement was to design an advanced calculator that has a fraction feature that will simplify fractions. The project will accept a non-negative integer as a numerator and a positive integer as a denominator and outputs the fraction in simplest form. That is, the fraction cannot be reduced any further, and the numerator will be less than the denominator.
 
Help Pasha to program her advanced calculator and succeed in her first ever project presentation. You can assume that all input numerators and denominators will produce valid fractions.

Hence create a class named Fraction with the following method.

 

Method NameDescription
void printValue(int,int)This method should display the fraction in simplest form.

 

Create a driver class called Main. In the Main method, obtain input from the user in the console and call the printValue method present in the Fraction class.
 
[Note: Strictly adhere to the Object Oriented Specifications given in the problem statement.
All class names, attribute names and method names should be the same as specified in the problem statement. Create separate classes in separate files.]


Input Format:
First line of the input is a non-negative integer which is the numerator in the fraction.
Second line of the input is a positive integer which is thedenominator in the fraction.

Output Format:
Output the simplified form of the fraction in a single line.
Refer sample input and output for formatting specifications.

            if(num==0)
            {
                System.out.println(num);
            }
            else if((num%den)==0)
            {
                System.out.println(num/den);
            }
           
           else{
               int hcf = findHCF(num,den);
               
               if(hcf==1)
               {

SUM OF AN ARRAY

  Sum of an array


Write a program to find the sum of the elements in an array using for each loop.

Input Format:

Input consists of n+1 integers. The first integer corresponds to ‘n’ , the size of the array. The next ‘n’ integers correspond to the elements in the array. Assume that the maximum value of n is 15.

Output Format:

Refer sample output for details.

All text in bold corresponds to the input and remaining corresponds to the output.

Sample Input 1:

Enter n :
5
2
3
6
8
1

Sample Output 1:

Sum of array elements is : 20

Sample Input 2:

Enter n :
4
5
9
45
14

Sample Output 2:

Sum of array elements is : 73
