Hi folks, I have same problem with coding!!!
Hi
I have problems with output. It's should Print only 10 numbers per line.
numbers per line should be controlled by a static variable.
public static int getNumber(Scanner inputfile, PrintWriter output ){ }
Here is the program:
package chapt07;
import java.util.*;
import java.io.*;
public class CHO7EX11 {
public static final int N = 10;
@SuppressWarnings("unused")
private static final int getNumber = 0;
public static void main(String[] args) throws FileNotFoundException {
int sumNumbers = 0;
int totalNumbers = 0;
IntClass oddCounter = new IntClass(), evenCounter = new IntClass(), zeroCounter = new IntClass();
Scanner input = new Scanner(new FileReader("src///CHO7EX11data.txt"));
PrintWriter output = new PrintWriter("src//CHO7EX11out.txt");
while (input.hasNext()) {
int number = getNumber(input, output);
sumNumbers += number;
totalNumbers++;
if (totalNumbers % N == 0) {
System.out.println();
output.println();
}
classifyNumber(number, zeroCounter, evenCounter, oddCounter);
}
printResult(output, totalNumbers, sumNumbers, evenCounter, zeroCounter,
oddCounter);
input.close();
output.close();
}
private static int getNumber(Scanner input, PrintWriter output) {
int anInt = input.nextInt();
System.out.println(anInt);
output.println(anInt);
return anInt;
}
private static void classifyNumber(int number, IntClass oddCounter,
IntClass zeroCounter, IntClass evenCounter) {
switch (number % 2) {
case 0:
evenCounter.addToNum(1);
if (number == 0)
zeroCounter.addToNum(1);
;
break;
case 1:
case -1:
oddCounter.addToNum(1);
}
}
private static void printResult(PrintWriter output, int totalNumbers,
int sumNumbers, IntClass zeroCounter, IntClass oddCounter,
IntClass evenCounter) {
System.out.println(" " + totalNumbers + " read.");
System.out.println(" " + sumNumbers + " is total.");
System.out.println(" " + sumNumbers / totalNumbers + " is average.");
System.out.println("Total numbers of odds: " + oddCounter);
System.out.println("There are " + zeroCounter + " Zeros.");
System.out.println("Total evens are: " + evenCounter);
output.println(" " + totalNumbers + " read.");
output.println(" " + sumNumbers + " is total.");
output.println(" " + sumNumbers / totalNumbers + " is average.");
output.println("Total numbers of odds: " + oddCounter);
output.println("There are " + zeroCounter + " Zeros.");
output.println("Total evens are: " + evenCounter);
}
}
and the input file include (like example) this numbers
0 0 -2 -3 -5 6 7 8 0 3 0 -23 -8 0 2 9 0 12 67 54
I don't now how to do it 10 numbers per line.
The program execute every number on single row.
Some advise???
Thank's
