in java Declare a FileOutputStream named outStream and a PrintWriter named dataFS. Ex: If the input is leek.txt 37.5, then leek.txt contains: 37.5 kilograms of leeks 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 import java.io.IOException; public class LeekFileOutput { publicstaticvoidmain(String[] args) throwsIOException { Scannerscnr=newScanner(System.in); StringleekFileName; doubleleekQuantity; /* Additional variable declarations go here */ leekFileName=scnr.next(); outStream=newFileOutputStream(leekFileName); dataFS=newPrintWriter(outStream); leekQuantity=scnr.nextDouble(); dataFS.println(leekQuantity+" kilograms of leeks"); dataFS.close(); } }
JAVA CODE can only be added inbetween lins of grey code. Like in the image 10-13 lines Perform the following tasks: Declare a FileInputStream named gradeFStream, and a Scanner named gradeFileFS. Read string dataFileName from input. Assign gradeFStream with a FileInputStream that opens the file dataFileName for reading. Assign gradeFileFS with a Scanner created using gradeFStream. Ex: If the input is grade3.txt and: Contents of file grade3.txt F then the output is: F grade1.txt Line 1 D grade2.txt Line 1 A grade3.txt Line 1 F
in java Variables bananaStream and bananaDataFS are FileOutputStream and PrintWriter, respectively. String bananaDataName is assigned a file's name read from input. Perform the following tasks: Assign bananaStream with a new FileOutputStream that opens bananaDataName for writing. Assign bananaDataFS with a new PrintWriter created using bananaStream. Ex: If the input is note.txt Ina, then note.txt contains: Ina ordered bananas 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 public class BananaDataProcessor { publicstaticvoidmain(String[] args) throwsIOException { Scannerscnr=newScanner(System.in); StringbananaDataName; StringbananaPurchase; FileOutputStreambananaStream=null; PrintWriterbananaDataFS=null; bananaDataName=scnr.next(); /* Your code goes here */ bananaPurchase=scnr.next(); bananaDataFS.println(bananaPurchase+" ordered bananas"); bananaDataFS.close(); } }

in java Integer cradleQuantity and string friendName are read from input. A FileOutputStream named fileStream is declared and the file named cradle.txt is opened. Then, a PrintWriter named cradleWriter is declared and associated with the file. Write the following to the opened file: "Remember:" "* * * *" cradleQuantity, followed by " cradles for " and friendName Another "* * * *" End each output with a newline. Finally, close the file. Ex: If the input is 12 Dax, then cradle.txt contains: Remember: * * * * 12 cradles for Dax * * * * Note: Data written to a file may be lost if the file is not closed. 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 public class FileOutput { publicstaticvoidmain(String[] args) throwsIOException { Scannerscnr=newScanner(System.in); FileOutputStreamfileStream=null; PrintWritercradleWriter=null; intcradleQuantity; StringfriendName; cradleQuantity=scnr.nextInt(); friendName=scnr.next();…
