Interfaces for Custom Document Printing in Java

Create a Java program to demonstrate the use of an interface for custom document printing

The DocumentPrinter interface declares two methods: printDocument for printing a document and cancelPrinting for canceling the printing process.
In the main method of the Main class, an anonymous class is created that implements the DocumentPrinter interface.
Inside the anonymous class, the printDocument method prints the document to the console, and the cancelPrinting method cancels the printing process.
A sample document string is created.
The printDocument and cancelPrinting methods of the DocumentPrinter interface are called to demonstrate printing and canceling printing.

Source Code

interface DocumentPrinter
{
	void printDocument(String document);
	void cancelPrinting();
}
 
public class Main
{
	public static void main(String[] args)
	{
		DocumentPrinter documentPrinter = new DocumentPrinter()
		{
			@Override
			public void printDocument(String document)
			{
				System.out.println("Printing document : " + document);// Implement document printing logic here
			}
 
			@Override
			public void cancelPrinting()
			{
				System.out.println("Document printing canceled");// Implement cancel printing logic here
			}
		};
 
		String document = "Sample Document";
 
		documentPrinter.printDocument(document);// Print document
 
		documentPrinter.cancelPrinting();// Cancel printing
	}
}

Output

Printing document : Sample Document
Document printing canceled
