I'm working on a Java assignment that processes image files. I need to modify this while loop somehow so that after the condition (y < x) is no longer true it creates a new array and continues to shove data from the rest of the file into the next array. Is there any way to do this? Any help is appreciated.
import java.util.Scanner; import java.io.File;
public class processor { public static void main ( String args[] ) { try { System.out.print ( " PPM Image Processor " );
// Create a regular Scanner for keyboard input Scanner keyboard = new Scanner ( System.in ); // Create a String variable and read the filename System.out.print ( " Enter input filename: " ); String inFile;
inFile = keyboard.next();
// Create a File variable based on the inFile file name File file = new File( inFile ); // Create a Scanner attached to the file instead of System.in // Used for file input!!! Scanner input = new Scanner ( file );
// Read the "magic number"! String first = input.next();
// Read number of columns from the file int column = input.nextInt();
// Read number of rows from the file int row = input.nextInt();
// Read max value from file int max = input.nextInt();
// Loop that reads the rest of the int data from the file int x = ( column * 3 ); System.out.printf ( "%d columns and %d rows", column, row ); int y = 0; int RGB[] = new int [x]; System.out.printf ( " Read %d numbers from file!", x ); while ( input.hasNext() && y < x ) { int v = input.nextInt(); RGB[y] = v; y++; } }
catch ( Exception ex ) { System.out.println ( "An error has occurred!" ); ex.printStackTrace(); } } }
