Hey everybody,
i wanna use the array "intArray" in the class eightPuzzleAStarDemo() as initial state but i get a cannot use it.
Does anybody has a hint for me?
Is it because it is not in the same package?
Thank you
package aaa.mayerp.projectone;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class Intro {
public static void main(String[] args) throws IOException {
String[] temp;
InputStreamReader inputStream = new InputStreamReader(System.in);
BufferedReader keyboard = new BufferedReader(inputStream);
System.out.println("Enter eight numbers from 0 to 9");
String initialstate = keyboard.readLine();
String delimiter = ",";
temp = initialstate.split(delimiter);
int[] intArray = new int[temp.length];
for (int i = 0; i < temp.length; i++) {
for (int x = 0; x < temp.length; x++) {
try {
intArray[x] = Integer.parseInt(temp[x]);
} catch(NumberFormatException e) {
System.out.println("Invalid int encountered:- " + temp[x]);
}
}
}
System.out.println("Numbers array contents: ");
for (int num: intArray) {
// System.out.println("Number: [" + num + "]");
System.out.println(num);
}
}
