I'm working on setting up a while()
that executes until the user enters an integer. However, the way I have it now, the loop prints the message "Please enter an integer"
again after the integer has been entered, and then the program executes normally. Can someone suggest a way to make not print that message again after an integer has been entered? Thanks!
System.out.println("Enter word length");
if(in.hasNextInt())
{
n = in.nextInt();
}
else
{
while(in.hasNext()) //this is the loop i'm talking about
{
System.out.println("Please enter an integer");
if(in.hasNextInt())
{
n = in.nextInt();
break;
}
else
{
String c = in.next();
}
}
}
I am assuming that you want user to enter int (or Integer) and repeatedly ask user until user enters int(or Integer). If so, try this:
System.out.println("Enter word length");
if(in.hasNextInt()) {
n = in.nextInt();
} else {
while(in.hasNext()) //this is the loop i'm talking about
{
if(in.hasNextInt())
{
n = in.nextInt();
break;
}
else
{
String c = in.next();
System.out.println("Please enter an integer");
}
}
}
