Question

I have my assignment printing, but I can find why the flowers is printing null and not the type of flower.

Instructions

1. Make sure the source code file named Flowers.java is open.
2. Declare the variables you will need.
3. Write the Java statements that will open the input file, flowers.dat, for reading.
4. Write a while loop to read the input until EOF is reached.
5. In the body of the loop, print the name of each flower and where it can be grown (sun or shade) using a format of flowerName + " is grown in the " + sunOrShade).
6. Execute the program

import java.io.*; // Import class for file input.

public class Flowers
{
public static void main(String args[]) throws Exception
{
// Declare variables here
String flowerName;
String sunOrShade = "flowers.dat";
  
// Open input file.
FileReader fr = new FileReader("flowers.dat");
  
// Create BufferedReader object.
BufferedReader br = new BufferedReader (fr);
  
// Write while loop that reads records from file.
while ((flowerName = br.readLine()) !=null)
{
sunOrShade = br.readLine();
}
System.out.println("Flowers " + flowerName + " is grown in the " + sunOrShade);

br.close();
System.exit(0);
} // End of main() method.

} // End of Flowers class.

Answer 1

import java.io.*; // Import class for file input.

public class Flowers {

public static void main(String args[]) throws Exception {

// Declare variables here

String flowerName;

String sunOrShade = "flowers.dat";

// Open input file.

FileReader fr = new FileReader("flowers.dat");

// Create BufferedReader object.

BufferedReader br = new BufferedReader(fr);

// Write while loop that reads records from file.

while ((flowerName = br.readLine()) != null) {

sunOrShade = br.readLine();

System.out.println("Flowers " + flowerName + " is grown in the " + sunOrShade);

}

br.close();

System.exit(0);

} // End of main() method.

} // End of Flowers class.
