Write some code that will create a stream named outStream that is anobject of the class PrintWriter and that connects this stream to a textfile named sam.txt so that your program can send output to the file. Ifthe file sam.txt does not exist, create a new empty file. However, if a filenamed sam.txt already exists, erase its old contents so the program canstart with an empty file with that name.
Write some code that will create a stream named fileIn that is a member ofthe class BufferedReader and that connects the stream to a text file namedjoe so that your program can read input from the text file joe.

- Write a program that gives and takes advice on program writing. The pro- gram starts by writing a piece of advice to the screen and asking the user to type in a different piece of advice. The program then ends. The next person to run the program receives the advice given by the person who last ran the program. The advice is kept in a file, and the contents of the file change after each run of the program. You can use your editor to enter the initial piece of advice in the file so that the first person who runs the program receives some advice. Allow the user to type in advice of any length so that it can be any number of lines long. The user is told to end his or her advice by pressing the Return key two times. Your program can then test to see that it has reached the end of the input by checking to see when it reads two consecutive occurrences of the character '\n'.arrow_forwardWrite a program that reads student data from a file, compute their GPA and writes the results to a different file. 1.

Each word in these files is on a separate line and the words contain only lowercase letters. Your task is to write a program that reads all these words from the file and checks if a keyword, which the user entered, is among the entered words. The program should also count the total number of words contained in the file used. The program should measure how long it takes to complete the search, ie how long it takes to read all the words and check if the keyword is among the words or not.
