进行此分配时，我需要打印方法的结果，但是我无法弄清楚如何调用它们。

public static int numWhitespace(String s) {

    int count = 0,x;
    for(x = 0; x<s.length();x++)
      if(Character.isWhitespace(s.charAt(x)))
         count++;
    return count;
}

public static void main (String[] args) {

    Scanner kb = new Scanner(System.in);
    System.out.println("Enter a string for character classification: (EOF to end):");
    while (kb.hasNext()){
       String input = kb.nextLine();
       System.out.println("inputLine = "+ input +"");

       System.out.println("inputLine is "+ input.length() +" characters long and contains the following:");

       System.out.println(); //Where i want all the other stuff

       System.out.println("Enter a string for character classification: (EOF to end):");
    }
}

您可以像这样调用numWhitespace()方法：

System.out.println("whitespaces = " + numWhitespace(input));

或先将其保存在变量中：

int whitespaces = numWhitespace(input);
System.out.println("whitespaces = " + whitespaces);

如何调用打印方法？
