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(); } }
