check if integer or string

oops, I am sorry, That's my fault, I ahave not explained to you.

Scanner class has many methods called hasNextXxx() each one just checks for the existing of the next token of the desired type, and not iterate over the next token, the method which gets the next token is nextXxx().

the following code should work(配 郧?轻徨):

import java.util.Scanner;

public class ScannerTest

{

public static void main(String args[]) {

String s = "Mary 33 London 410";

Scanner sc = new Scanner(s);

while (sc.hasNext() )

{

//System.out.println("Before IF ELSE");

if (sc.hasNextInt())

{

int number = sc.nextInt();

System.out.println("number: " + number);

// do something......

}

// .... and so............

else

{

String str = sc.next();

System.out.println("string: " + str);

}

}

}

}

Good Luck
