Problems with counting spaces - Java

I'm having problems with the code below. It asks for the user to type in a sentence basically.

System.out.println("Enter a string containing spaces: ");
inputString = keyboard.next();
int lengthString = inputString.length();

System.out.println("You entered: " + inputString + "\n" + "The string length is: " + lengthString);

The problem is when it prints the statement, it only prints the first word, then counts the characters contained within the first word. I'm really new to Java, so I was wondering what should I do to make the program count the WHOLE string.

keyboard.nextLine() will pull in the entire line. next() only gets the next word. next() uses spaces by default to determine word sizes, but you can also set a custom delimiter if you want it to pull in different tokens.

You should use nextLine() method instead of next():

inputString = keyboard.nextLine();

Scanner#next() method reads the next token. Tokens are considered to be separated by a delimiter. And the default delimiter of Scanner is as recognized by Character.isWhitespace.
