String doesn't match regex when read from keyboard.
- by athspk
public static void main(String[] args) throws IOException {
String str1 = "??123456";
System.out.println(str1+"-"+str1.matches("^\\p{InGreek}{2}\\d{6}")); //??123456-true
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String str2 = br.readLine(); //??123456 same as str1.
System.out.println(str2+"-"+str2.matches("^\\p{InGreek}{2}\\d{6}")); //?”??123456-false
System.out.println(str1.equals(str2)); //false
}
The same String doesn't match regex when read from keyboard.
What causes this problem, and how can we solve this?
Thanks in advance.
EDIT: I used System.console() for input and output.
public static void main(String[] args) throws IOException {
PrintWriter pr = System.console().writer();
String str1 = "??123456";
pr.println(str1+"-"+str1.matches("^\\p{InGreek}{2}\\d{6}")+"-"+str1.length());
String str2 = System.console().readLine();
pr.println(str2+"-"+str2.matches("^\\p{InGreek}{2}\\d{6}")+"-"+str2.length());
pr.println("str1.equals(str2)="+str1.equals(str2));
}
Output:
??123456-true-8
??123456
??123456-true-8
str1.equals(str2)=true
