- 15). (Remove text) Write a program that removes all the occurrences of a specified string from a text file. (For example, my Aunt went to buy Medicines while Sam and I play Soccer. Removes the string Sam from the file.) 1) You should create a file with this paragraph. 2) removes the string "John and" from the file. Note:- Please write a java code and also need an output for this program. (Also, let me know with what name file should be saved to get output)arrow_forward<<Write in Java>> - Challenge 7 File encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded contents out to a second file. The second file will be a version of the first file, but written in a secret code. Although there are complex encryption techniques, you should come up with a simple one of your own. For example, you could read the first file one character at a time, and add 10 to the character code of each character before it is written to the second file. - Challenge 8 Write a program that decrypts the file produced by the program in Programming Challenge 7. The decryption program should read the contents of the coded file, restore the data to its original state, and write it to another filearrow_forwardNote:- Please type this java program and give the output for this code.arrow_forward
- ENGAGE MINDTAP -Using a Counter-Controlled while Loop in Java Using a Counter-Controlled while Loop ? Summary In this lab, you use a counter-controlled while loop in a Java program provided for you. When completed, the program should print the numbers 0 through 10, along with their values multiplied by 2 and by 10. The data file contains the necessary variable declarations and some output statements. Instructions 1. Ensure the file named Multiply.java is open. 2. Write a counter-controlled while loop that uses the loop control variable to take on the values O through 10. Remember to initialize the loop control variable before the program enters the loop. 3. In the body of the loop, multiply the value of the loop control variable by 2 and by 10. Remember to change the value of the loop control variable in the body of the loop. 4. Execute the program by clicking Run. Record the output of this program. Grading When you have completed your program, click the Submit button to record your…arrow_forwardIf you write string "ABC" to an ASCII text file, what values are stored in a file?arrow_forwardNOTE:- Please type this java code and need an output also, even explain how to work this code. (Also tell how to create the text file for this code if necessary please)arrow_forward
- 5) Practice: Write a program that randomly generates the ages of 100 people between the values of 0 and 110. Do not give all ages equal weight, but let older ages be less likely. Hint: try taking one minus the negative exponential of a random number and multiplying the result by 110, 110*(1-exp(-rand(1,100))). Export this to a txt data file.arrow_forwardWhen you open a file for reading, what happens if the file does not exist? When you open a file for writing, what happens if the file already exists?arrow_forwardLANGUAGE: C++ Create a program and then: Show file input (get your input from a file) File output (output to a file) File append (add to the end of a file) Also,Try to have your code handle an error if for example you try to read from a file that doesn’t exist.arrow_forward
