problem with scanner

[fiction]

hi people. i recently started with java and stuck on one thing.
i was doing something with scanner and noticed a problem


Scanner entry = new Scanner(System.in);
double stnm, ndnm, res;
System.out.println("Enter 1st number: ");
stnm = entry.nextDouble();
System.out.println("Enter 2nd number: ");
ndnm = entry.nextDouble();
res = stnm+ndnm;
System.out.println(res);
System.out.println("Hi. What's your name?");
String a = entry.nextLine();
System.out.println("Hi "+a);

why does scanner skip this line
i can enter first 2 integers but when i should be able to enter string it just skips that line.
why is it so? how can i fix that?

Before you want to read an entire line, you wanted to read a double; the nextDouble() method does just that and it doesn't read an end-of-line character that most likely was typed by you. The nextLine() method does see that end-of-line character and assumes that it had read an empty line. The remedy is simple: after the last nextDouble() call, call nextLine() to get rid of that empty line.

kind regards,

Try this:

String a = entry.next();
