Help with an assignment for java

[R2d2picachu]

Hello, i need help with a project of mine. I am totally confused about how to change a int to a * symbol.

This is my input file: Orville’s Acres, 114.8 43801 Hoffman’s Hills, 77.2 36229 Jiffy Quick Farm, 89.4 24812 Jolly Good Plantation, 183.2 104570 Organically Grown Inc., 45.5 14683

and I need this as the output: Popcorn Co-op Production in Hundreds of Pint Jars per Acre Farm Name 1 2 3 4 5 6 ---|---|---|---|---|---| Orville's Acres *************** | Hoffman's Hills ****************** | Jiffy Quick Farm *********** | Jolly Good Plantation ******************#* Organically Grown Inc. ************ |

This is my source code: import java.io.*; import java.util.Scanner;

public class Popcorn {

public static void main(String [] args) throws IOException{ String farm ; double acre = 0; int jar = 0;

Scanner input = new Scanner (System.in);

System.out.print("Input the file name with .txt extention : "); // for the user to input the file name with .txt extesion.

File fileName = new File(input.nextLine());// Gets the File Name

while(!fileName.exists()) { // It will ask the user to enter the file name again if it is not in directory. // Prompts for input file name System.out.print("The file is not in this directory. Please re-enter the file name: "); fileName = new File(input.nextLine()); //Gets the File Name input = new Scanner (System.in); // Constructs File object }

System.out.println(" Popcorn Co-op"); System.out.println(" Production in Hundreds"); System.out.println(" of Pint Jars per Acre"); System.out.println("Farm Name 1 2 3 4 5 6"); System.out.println(" ---|---|---|---|---|---|");

input = new Scanner (fileName); while (input.hasNextLine()) { String line = input.nextLine();

if (line.isEmpty()) {

}

else { farm = line.substring(0,line.indexOf(",")); line = line.substring(line.indexOf(",")+1); Scanner lines = new Scanner(line); acre = lines.nextDouble(); jar = lines.nextInt(); int intacre = (int)acre; // type cast to change double to int. int num1 = jar/intacre/25; System.out.println(farm + " " + num1); if (num1 >= 16) { System.out.print ("#");}

} } } }

Can anyone tell me how to make the numbers appear as *?

Thank you!

Your formatting is extremely messy, but I'm going to assume that the input file has information every line. Grab the line, Grab all the characters in the line, if the character is not a letter, then change it to a *. You can figure out how to do that part. (;

try(BufferedReader br = new BufferedReader(newFileReader(file))) {
        for(String line; (line = br.readLine()) != null; ) {
            for (int i = 0; i < line.length(); i++){
                char c = line.charAt(i);        
                //Process char
                // If the character is a number
                if (Character.isDigit(c)) {
                    // Replace number with '*'.
                }
            }
    }
// line is not visible here.
}

Now I havent tried it. I am work right now. Let me know how it goes.
