Thread: Print to txt file

My current code will generate a txt file that includes "Instrument [i] : " and then the boolean values (true or false) of the four methods that I've created. However, I want the text file to include output such as this here. Any help is greatly appreciated.

cello1 is tuned. cello1.tuneInstrument = (boolean value)
cello1 is playing. cello1.playInstrument = (boolean value)
cello1 is not playing. cello1.stopPlaying = (boolean value)
cello1 is ready for concert. cello1.readyConcert = (boolean value)

/*

package instruments;

import java.io.File;
import java.io.FileNotFoundException;

public class TestInstruments {
public static void main(String[] args) throws FileNotFoundException{

Instruments cello = new Instruments();
File file = new File("AshleyMasonp3test.txt");

if (file.exists()){
System.out.println("File already exists");
System.exit(0);
}

try (java.io.PrintWriter output = new java.io.PrintWriter(file)) {

int i = 1;
while (i < 11) {
System.out.println("Instrument " + i + ":");
output.println("Instrument " + i + ":");
output.println(cello.tuneInstrument());
output.println(cello.playInstrument());
output.println(cello.stopPlaying());
output.println(cello.readyConcert());
i++;
}
}
}
}

So with the while loop, instead of printing, cello1 is tuned. cello1.tuneInstrument = true, the text file will have only the value of true.

int i = 1; 
while (i < 11) {
System.out.println("Instrument " + i + ":");
output.println("Instrument " + i + ":");
output.println(cello.tuneInstrument());
output.println(cello.playInstrument());
output.println(cello.stopPlaying());
output.println(cello.readyConcert());
i++;
}
}
}

Should that if statement be included in the while loop? The reason I'm asking is the tuneInstrument has to be a boolean field. Thus, I have this code for that method.

 public boolean tuneInstrument(){
     System.out.println("The instrument is tuned.");
     return isTuned = true;
 }
