Reading multiple input types from a scanner.

Question:

How do you read multiple input types from a scanner?

Answer:

Here is an example.

Code:

import java.util.Scanner;
 
public class ReadInput {
 
   public static void main(String[] args) {
 
      Scanner sc = new Scanner(System.in);
 
      System.out.print("Enter first string: ");
      String str1 = sc.nextLine();
 
      System.out.print("Enter first int: ");
      int i1 = sc.nextInt();
      sc.nextLine();  // needed to empty buffer
 
      System.out.print("Enter second string: ");
      String str2 = sc.nextLine();
 
      System.out.print("Enter second int: ");
      int i2 = sc.nextInt();
 
      System.out.println("First string: " + str1);
      System.out.println("Second string: " + str2);
 
      System.out.println("First int: " + i1);
      System.out.println("Second int: " + i2);
 
      sc.close();
   }
}

Output:

$ java ReadInput 
Enter first string: the cat in the hat
Enter first int: 100
Enter second string: i like java
Enter second int: 200
First string: the cat in the hat
Second string: i like java
First int: 100
Second int: 200
