I keep getting an error with my code specifically at
ArrayList<String> input[i]= (i + 1) + " " + ArrayList<String> input[i];
the error tells me "; expected" what am I doing wrong here?
Scanner scnr = new Scanner(System.in);
System.out.println("how many lines of text do you want to enter");
int numLines = 0;
numLines = scnr.nextInt();
System.out.println();
ArrayList lines = new ArrayList();
scnr.nextLine();
int i = 0;
do{
System.out.println("Enter your text: ");
String text = scnr.nextLine();
ArrayList<String> input = new ArrayList<String>();
i++;
for (i = 0; i < numLines; i++)
{
ArrayList<String> input[i]= (i + 1) + " " + ArrayList<String> input[i];
}
for (String element: ArrayList<String> Lines)
{
System.out.println(element);
}
} while(i != 0);
As you have
ArrayList<String> input = new ArrayList<String>();
within your loop, it means that it will get re-declared and initialised for every iteration of that loop, so move this declaration to before your do
Next, to add to this loop, use add
method
String text = scnr.nextLine();
input.add (text);
To simplify, you do not need a do
as you have a number of times that you want to loop
Scanner scnr = new Scanner(System.in);
System.out.println("how many lines of text do you want to enter");
int numLines = scnr.nextInt();
System.out.println();
scnr.nextLine();
ArrayList <String> lines = new ArrayList <> ();
for (int i = 0; i < numLines; i++) {
System.out.println("Enter word...");
String text = scnr.nextLine();
lines.add(text);
}
To print your list, you can then do
for (int x = 0; x < lines.size(); x++) {
System.out.println (lines.get(x));
}
output
how many lines of text do you want to enter
5
Enter word...
one
Enter word...
two
Enter word...
three
Enter word...
four
Enter word...
five
one
two
three
four
five
