Class Homework assignment 4
Write a Java program to achieve the following: – First, create an algorithm to solve this problem.
Ask the user for a search-word to be found in the text of an input file.
Read each line of the input.txt file (supplied by you), and search each line to see if it contains the search
word. If the search-word is found within the line of text, then output that line to an output.txt file, and
display the line on the screen with an indication that the line contains the search-word (prefix the line
with [sw found]). Lines not containing the sw should just be written as is to the screen.
Example of input.txt
In-class assignment 1
Create a java program to achieve the following:
Ask the user for the number of integers to randomly generate.
Create an integer array of the appropriate size and insert the randomly generated integers (in the range 1 –
100) into the array.
Ask the user for a search value (integer), then check to see if the array contains this value and display a
message to indicate if found or not.
Finally, display the contents of the array, the sum of the numbers in the array, the smallest value and the
largest value in the array.

In-class assignment 1
[sw found] Create a java program to achieve the following:
[sw found] Ask the user for the number of integers to randomly generate.
[sw found] Create an integer array of the appropriate size and insert the randomly generated integers
[sw found] (in the range 1 – 100) into the array.
[sw found] Ask the user for a search value (integer), then check to see if the array contains this value
and display a message to indicate if found or not.
[sw found] Finally, display the contents of the array, the sum of the numbers in the array, the smallest
value and the largest value in the array.

 Request the input/output file names from the user
 Place the search word inside the marker. For example, if the search word was the, then the
marker would be [the found]
 Modify the file output to append to the existing file rather than overwriting the data
 Make the search case-insensitive (the The THE)
Extra-extra credit
 Include the number of times the search word appears in the line
For example, line 5 would show as:
[the found (4) times] Create an integer array of the appropriate size and insert the randomly
generated integers (in the range 1 – 100) into the array.
