Answer:
Follows are the code to this question:
import java.util.*;//import packae for user-input
public class Main//defining a class Main
{
public String[] getArray(int numString)//defining a method getArray
{
String[] name=new String[numString];//defining array of String values
Scanner in = new Scanner(System.in);// creating scanner class object for input values from user-end
for(int i=0;i<numString;i++)//defining for loop for input multiple values
{
System.out.print("Enter String Value :");//print message
name[i]=in.nextLine();//input values
}
return name;//return array values
}
public String getLongestString(String[] sArray)//defining a method getLongestString
{
int m=0,mi=0; //defining integer variables
for(int i=0;i<sArray.length;i++)//defining for loop for check the longest value in array
{
if(m<sArray[i].length())//defining if block that checks m varaible value greater then sArray length
{
m=sArray[i].length();//use m to hold sArray length
mi=i;//use max_index to hold i that is loop value
}
}
return sArray[mi];//return Longest value
}
public static void main(String[] args)//defining main method
{
Main s=new Main();//Creating object of main class
String[] n;//defining string variable n
n=s.getArray(5);//use n varaible to call getArray method and store its value
System.out.println("Longest value is: "+s.getLongestString(n));//use print method to call getLongestString method
}
}
Output:
please find attached file.
Explanation:
In the given java program code, inside the main class two method that is "getArray and getLongestString", is defined, in which the "getArray" method uses an integer variable in its parameter and inside the method, an array is defined that use a scanner class for input array value.
- In the "getLongestString" pass as a parameter and inside the method, two integer variable "m and mi" is defined that use in the loop to return the longest string value.
- In the class main method is to define that creates a class object and call the above method and use the print method to return its value.
Answer:
Here is the Python program.
characters = 0
words = 0
lines = 0
def file_stats(in_file):
global lines, words, characters
with open(in_file, 'r') as file:
for line in file:
lines = lines + 1
totalwords = line.split()
words = words + len(totalwords)
for word in totalwords:
characters= characters + len(word)
file_stats('created_equal.txt')
print("Number of lines: {0}".format(lines))
print("Number of words: {0}".format(words))
print("Number of chars: {0}".format(characters))
Explanation:
The program first initializes three variables to 0 which are: words, lines and characters.
The method file_stats() takes in_file as a parameter. in_file is the name of the existing text file.
In this method the keyword global is used to read and modify the variables words, lines and characters inside the function.
open() function is used to open the file. It has two parameters: file name and mode 'r' which represents the mode of the file to be opened. Here 'r' means the file is to be opened in read mode.
For loop is used which moves through each line in the text file and counts the number of lines by incrementing the line variable by 1, each time it reads the line.
split() function is used to split the each line string into a list. This split is stored in totalwords.
Next statement words = words + len(totalwords) is used to find the number of words in the text file. When the lines are split in to a list then the length of each split is found by the len() function and added to the words variable in order to find the number of words in the text file.
Next, in order to find the number of characters, for loop is used. The loop moves through each word in the list totalwords and split each word in the totalwords list using split() method. This makes a list of each character in every word of the text file. This calculates the number of characters in each word. Each word split is added to the character and stored in character variable.
file_stats('created_equal.txt') statement calls the file_stats() method and passes a file name of the text file created_equal.txt as an argument to this method. The last three print() statements display the number of lines, words and characters in the created_equal.txt text file.
The program along with its output is attached.
