How do you input a list of numbers into a scanner for a loop to process them in many ways?
I am trying to get the scanner to allow me to input an undefined list of numbers but when I try to use an array, it throws an error saying that you can't use int [] with int. I have that same issue with the rest of the code as well, when I attempt to write in odd and even counts, averages....etc. Here is the first part that I am trying to use now. I have five variables listed but would like to be able to list an undefined amount if possible. Thank you. int [] x = new int [5]; int values == x; System.out.println("Enter a series of values (0 to quit):"); values = in.nextInt(); while (values != 0) { System.out.println(values);

int [] x = new int [5];
for(int i = 0; i < x.length; i++){
Scanner in = new Scanner(System.in);
System.out.println("Enter a series of values (0 to quit):");
int values = in.nextInt();
x[i] = values;
}
for(int y: x){
System.out.println("x: " + y);
}

The phone has, for example, Java N-IDE and AIDE. I write all the code there, and the data recording takes place in stages. And not as here all at once. For example, in the Java N-IDE asks 5 times when there will be data entry and there will be no errors in the code. Here it is not known initially how much data you need to enter

I have one more question. Is there a way to be able to run the five numbers against each other with the later parameters? Right now when I run the program, it does each number individually and does not compare them to each other. This is what I have right now and am not sure what I need to do.
int [] x = new int [5];
for(int i = 0; i < x.length; i++){
System.out.println("Enter a series of values (0 to quit):");
int values = in.nextInt();
x[i] = values;
for(int y: x)
System.out.println("x: " + y);
int largestNum = values;
if (values > largestNum)
largestNum = values;
System.out.println("The largest value is: " + largestNum);
int smallestNum = values;
if (values < smallestNum)
smallestNum = values;
System.out.println("The smallest value is: " + smallestNum);
if (values % 2 == 0)
evenNum ++;
else
oddNum ++;
System.out.println(evenNum + "even" + " " + oddNum + "odd");
}
}
}

I wrote a wonderful working version:
public static void main(String args[]){
ArrayList<Integer> arr = new ArrayList<Integer> ();
int start = 1;
int var = 0;
Scanner in = new Scanner(System.in);
while(start<=5){
var = in.nextInt();
System.out.println("var: " + (start++) + " = "+ var);
arr.add(var);
}
Random r = new Random();
if(arr.get(r.nextInt(5)) >= arr.get(r.nextInt(5))){
System.out.println(arr.get(r.nextInt(5)) + " >= " + arr.get(r.nextInt(5)));
}else{
System.out.println(arr.get(r.nextInt(5)) + " <= " + arr.get(r.nextInt(5)));
}
}
