How to use while loop for text file?

• I am having problem with the while loop for the text file. Can anyone help me please? Much help is appreciated. Thanks. Part A Instead of writing a separate line to read each word (or number / item) in your text file use a while loop and have the ending condition be the false for the next statement. Part B Generate 10 random numbers between 100 and 200 and write them to a text file. I get stuck at the while loop part for Part A. import java.io.File; import java.io.FileNotFoundException; import java.util.Scanner; public class Project7 { public static void main(String[] args) throws FileNotFoundException { File file = new File ("word.txt"); Scanner myScan = new Scanner (file); String fil = myScan.next(); System.out.println(fil); System.out.println(myScan.next()); System.out.println(myScan.next()); System.out.println(myScan.hasNext()); } }

• Answer:

  I think you need something like String fil; while ( (file = myScan.next())!= null){ System.out.println(fil); } or while(myScan.hasNext()){ System.out.println( myScan.next()); } hope it helps!
