How to Concatenate Strings Accurately in Java

When attempting to concatenate strings in Java, some developers encounter issues due to syntactic errors. An example of this is the following code:

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

The above code attempts to concatenate the string "Your number is " with the integer theNumber and the string "!". However, this syntax is incorrect. To concatenate strings correctly, you should use the plus ( ) operator:

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

In this corrected syntax, theNumber is implicitly converted to the string "42", resulting in the desired output: "Your number is 42!".
