I'm trying to write an application which takes an input file, and adds 5 blank
spaces at the beginning of each paragraph. Then the application is to write to
an output file with the new changes. The application will detect the beginning
of a new paragraph because there is a blank line before it. I test for the
blank using the following if statement.
if inputString.length() < 1
{
inputString = blanks+inFile.hasNextLine();
}
When I tried to compile the application using the javac program, I get the
following error.
History.java:23: incompatible types
found : boolean
required: java.lang.String
inputString = inFile.hasNextLine();
^
1 error
The source code for the application is below.
import java.io.*; // importing input.output classes
import java.util.Scanner;
public class History
{
public static Scanner inFile;
public static PrintWriter outFile;
public static void main(String[] args)
{
String inputString; // Input string from a line in file
final String blanks = " ";
// Five blanks inserted at beginning of each paragraph
inFile = new Scanner(new FileReader("history.d1"));
// Instantiating new scanner and new filereader object with
// history.d1 as argument
outFile = new PrintWriter(new FileWriter("history.d2"));
// Instantiating new printWriter object
// It will be used to write to a file
inputString = blanks+inFile.hasNextLine();
outFile.println(inputString);
while (inFile.hasNextLine())
{
inputString = inFile.hasNextLine();
if (inputString.length() < 1)
{
inputString = blanks+inFile.hasNextLine();
}
outFile.println(inputString);
}
inFile.close();
outFile.close();
}
}
What am I doing wrong?
