I am having problems with STDIN
I would to read the following 2 string, for example:
Input:
abc
xyz
When typing "abc", then press Enter, I get abc back. However i dont want that. I would like to type another string just like input above.
So what want is: Type abc, Enter, type xyz enter
here is my code:
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
String s;
while ((s = in.readLine()) != null && s.length() != 0){
System.out.println(s);
}
Thanks
You should use Scanners for this.
Here is an example implementing scanners:
Scanner scanner = new Scanner(System.in);
String s = scanner.nextLine();
String s2 = scanner.nextLine();
System.out.println(s + ":" + s2);
//Close scanner when finished with it:
scanner.close();
Here is the full documentation for further reading and examples: Oracle documentaion
Scanner is the preferred way to get input from the console. Example:
Scanner in = new Scanner(System.in);
System.out.print("Please enter a string: ");
String input = in.nextLine();
System.out.println("You entered: \"" + input + "\"");
Scanner also has other useful methods like nextInt and nextChar.
