Thread: Scanner object not allowing input

Hello friends,


Started learning Java last week. I have experience with C++ and the similarities between both are making it easier for me to understand Java.

A quick subquestion: Is the scanner class and scanner object the basic equivalent for console input (cin >> ) for C++? And is the + used as the insertion operator (>> and <<) when printing variables/etc? Please forgive my newbiness. I just want to catch and throw out any incorrect assumptions early.

Anyways, here is my code. My problem is that if I ask the user to input a string and then an integer, I get the expected output. If, however, I ask the user to input an int and then a string, after inputting the int, it terminates the program, not allowing me to input a string value in name.

import java.util.Scanner; //Needed for console input object
 
public class FirstClass {
public static void main (String [] args)
	{
 
		//User input with different data types
		Scanner scan = new Scanner(System.in);
 
		System.out.println("Enter your name: ");
		String name = scan.nextLine();
 
		System.out.println("Enter your age: ");
		int age = scan.nextInt();
 
		System.out.println("Your name is " + name + " and you are " + age + " years old.\n");
	}	
}
 
//OUTPUT: Your name is John Smith and you are 25 years old.

import java.util.Scanner; //Needed for console input object
 
public class FirstClass {
public static void main (String [] args)
	{
		//User input with different data types
		Scanner scan = new Scanner(System.in);
 
                System.out.println("Enter your age: ");
		int age = scan.nextInt();
 
		System.out.println("Enter your name: ");
		String name = scan.nextLine();
 
		System.out.println("Your name is " + name + " and you are " + age + " years old.\n");
	}	
}
//OUTPUT: Your name is and you are 25 years old.

Thanks in advance.

Thank you! I appreciate your time in answering my question Have a great day.
