hi! HELP ME!!!!!!!!!! :( :)
How to get answer 15 instead of 105 when user entered 10 as a number????? pls help!!!!!!
package userinputactivity;
import java.util.Scanner;
public class UserInputActivity {
public static void main(String[] args) {
Scanner name = new Scanner(System.in);
System.out.println("Please enter a number :");
int num2 = 5;
String num = name.next();
String total = (num + num2);
System.out.println("Answer is: " +total);
}
}
Re: hi! HELP ME!!!!!!!!!! :( :)
Please explain what the code is supposed to do.
The + operator does different things depending on the type of the operands it is used with.
When the operands are numeric, their values are added together: 5 + 10 = 15
When the operands are Strings, their values are concatenated: "5" + "10" = "510".
If mixed, the compiler converts the int to a String and concatenates them.

If you don't understand my answer, don't ignore it, ask a question.

In other words, instead of using the Scanner's next() method (which will get a string value), use the nextInt() method to get an int value.
