what does scan.hasnext do
The hasNext() method checks if the Scanner has another token in its input.
A Scanner breaks its input into tokens using a delimiter pattern,
which matches whitespace by default.
That is, hasNext() checks the input and returns true if it has another non-whitespace character.hasnext in java
import java.util.*;
import java.util.regex.Pattern;
public class ScannerDemo {
public static void main(String[] args) {
String s = "Hello World! 3 + 3.0 = 6";
// create a new scanner with the specified String Object
Scanner scanner = new Scanner(s);
// check if the scanner has a token
System.out.println("" + scanner.hasNext());
// print the rest of the string
System.out.println("" + scanner.nextLine());
// check if the scanner has a token after printing the line
System.out.println("" + scanner.hasNext());
// close the scanner
scanner.close();
}
