How do I concatenate two strings in Java?

Question

I am trying to concatenate strings in Java. Why isn't this working?

public class StackOverflowTest {       public static void main(String args[]) {         int theNumber = 42;         System.out.println("Your number is " . theNumber . "!");     } } 

Answer 1

You can concatenate Strings using the + operator:

System.out.println("Your number is " + theNumber + "!"); 

theNumber is implicitly converted to the String "42".
