Exercise a HelpMe test - bohh - Sep 28, 2020
given the two classes:
class Document {
private String type = "dummy";
private byte [] data;
// enter get and set //
public classTestClass {
public static void main (String [] args) {
Document d = new PdfDocument ();
System.out.prinln (d.getType ());
I will write the code for the PdfDocument class so that Test Class will print "pdf" when run.
??????

What part isn't clear to you? It seems to be a rather simple exercise that should take no more than 2 minutes of your time.
Inheritance and system.out.println are your friends.

I did it and print pdf, but I don't use that part of the code from the data array part ... but it works.
the pdfDocument
public class PdfDocument extends Document {
public String getType() {//Override del metodo in Document
return "PDF";
}
}
e il test:
public class TestClass {
public static void main(String[] args) {
Document d = new PdfDocument();
System.out.println(d.getType());
}
}
class Document {
private String type = "dummy";//dummy viene sovrascitto dalla classe PdfDocument
private byte[] data;
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public byte[] getData() {
return data;
}
public void setData(byte[] data) {
this.data = data;
}
}

You can use the Apache Commons Java library :
Code
FileUtils.readFileToByteArray(File)Where File is the object containing your pdf.
You can initialize it like so :
Code
File file = new File("/path/to/your/file.pdf");So it'll look like :
Code
File myPdf = new File("/path/to/your/file.pdf");
byte[] pdfByteArray = FileUtils.readFileToByteArray(myPdf);You'll maybe need to add a path variable to your Document object.
Whait.
