Hallo,
Kann mir jemand helfen und sagen, was ich hier wohl übersehen habe. 2 Klassen, runner class nimmt den user input als array. Runner class ruft Methode aus der class ab. Danke sehr!!!!

Code:
import java.util.Scanner;
public class RunnerList {
public static void main(String args[]) {
int number[] = new int[10];
Scanner scan = new Scanner(System.in);
System.out.println("Enter a list of 10 numbers.");
for (int i = 0; i < 10; i++) {
number[i] = scan.nextInt();
}
for (int i = 0; i < 10; i++)
System.out.print(number[i]);
List l = new List();
l.createLists(number);
System.out.println(l);
}
}
Code:
public class List {
private int[] evenList;
private int[] oddList;
private int[] negativeList;
private int evenCount = 0, oddCount = 0, negativeCount = 0;
public void createLists(int[] userInput) {
for (int i = 0; i < userInput.length; i++) {
if (userInput[i] < 0) {
negativeList[negativeCount] = userInput[i];
negativeCount++;
}
else if (userInput[i] % 2 == 0) {
evenList[evenCount] = userInput[i];
evenCount++;
}
else {
oddList[oddCount] = userInput[i];
oddCount++;
}
}
}
public String toString() {
int i;
String even = "";
String odd = "";
String negative = "";
for (i = 0; i < evenCount; i++)
even += evenList[i] + "";
for (i = 0; i < oddCount; i++)
odd += oddList[i] + " ";
for (i = 0; i < negativeCount; i++)
negative += negativeList[i] + " ";
String result = "Even List: " + even + "\nOdd List: " + odd + "\nNegative List: " + negative;
return result;
}
}
