用Scanner类的帮助，您可以从命令行输入并将每一行存储到String数组或ArrayList
public static void main(String[] args) {
ArrayList<String> in = new ArrayList<String>();
Scanner s = new Scanner(System.in);
while (s.hasNextLine()) {
String line = s.nextLine();
in.add(line);
if (line != null && line.equalsIgnoreCase("END")) {
System.out.println("Output list: " + in);
break;
}
}
}
英文:
With the help of Scanner class you can take input from cmd and store each line into Array of String or In ArrayList<String> collection.
public static void main(String[] args) {
ArrayList<String> in = new ArrayList<String>();
Scanner s = new Scanner(System.in);
while (s.hasNextLine()) {
String line = s.nextLine();
in.add(line);
if (line != null && line.equalsIgnoreCase("END")) {
System.out.println("Output list : " + in);
break;
}
}
}
