(Create a text file) Write a
Create a text file
Program Plan:
- Declare the class “writeText”.
- Definition for main class.
- Create an object to “PrintWriter” to create a new file named “Exercise17_01.txt”.
- For loop to iterate till 100.
- Write the 100 randomly generated integers to the file.
Program to create a file named “Exercise17_01.txt” to write 100 integers randomly to the created text file.
Explanation of Solution
Program:
//Import required packages
import java.io.*;
import java.util.*;
//Definition for class "writeText"
public class WriteText {
// Definition for main class
public static void main(String[] args) throws IOException {
// Try block
try (
/* Create an object for printWriter to write output to the text file */
PrintWriter out = new PrintWriter(new FileOutputStream(
"Exercise17_01.txt", true));)
{
// Loop to iterate
for (int j = 0; j < 100; j++)
// Generate the random number
out.print((int) (Math.random() * 100000) + " ");
}
}
}

- Show two different ways to reset the file position pointer to the beginning of the filearrow_forwardHow do you check for end of file when reading an input file using INT 21h Function 3Fh?arrow_forwarda. What happens if you try to move the file marker past the end of a file? b. What is returned if subsequent calls are made to read the file?arrow_forward
- What classes do you use to write output to a binary file? What classes do you use to read from a binary file?arrow_forwardWrite code that does the following: opens an output file with the filename number_list.txt, uses a loop to write the numbers 1 through 100 to the file, and then closes the file.arrow_forwardHow do you parse through this input file? C++arrow_forward
- What is the import file suposed to be?arrow_forwardUsing C++, write a fragment of code to open a file called random.txt. If the file does not exist, create and open it for both input and output. Then, write 10 consecutive random numbers in the range of 1 to 10 into the filearrow_forwardWhen you say a file is indexed, do you mean it has an index directory that allows for random access?arrow_forward
- State which of the following are true and which are false. If false, explain why.d) If the file position pointer points to a location in a sequential file other than the beginningof the file, the file must be closed and reopened to read from the beginning of the file.arrow_forwardHow do I seperate the parts of the code into different files properly?arrow_forwardHow do I write a code that will open the text file for reading, (test.txt), and that prints the first line of the file?arrow_forward
