Explanation / Answer
Dear,
Here is the code
import java.util.Scanner;
import java.io.*;
public class MultiplcationTable
{
public static void main(String[] args)throws IOException
{
String filename; // File name
// Create a Scanner object for keyboard input.
Scanner keyboard = new Scanner(System.in);
// Get the filename.
System.out.print("Enter the filename:");
filename = keyboard.nextLine();
File file=new File(filename);
PrintWriter output= new PrintWriter(file);
//loop repeats for tables
for(int i=1;i<=9;i++)
{
for(int j=1;j<9;j++)
{
output.print(i+"*"+j+"="+i*j);
output.print(" ");
}
output.println();
}
System.exit(0);
}
}
Hope this will help you..
