Gain insights into Java programming by exploring conditional statements, loops, math, logic, inheritance, generics, and arraylists, to become an intermediate Java developer.

Learn Java for free with this interactive course, and get a handle on one of the most popular programming languages in the world.

You'll start with a simple hello world program and proceed to cover common concepts such as Conditional Statements, Loop Statements, Math, and Logic in Java, before moving on to more advanced concepts like Inheritance, Generics, and ArrayLists, along with much more.

By the time you're done, you'll be an intermediate level Java developer, ready to take on your own projects.

# Solution: did you find the right words?

class HelloWorld {
    public static void main( String args[] ) {
        String text = "   Names!  Doe   ";
        String answer = "";
  
        answer = text.trim();
        answer = answer.substring(0, 6);
        answer = answer.toUpperCase();

        System.out.println(answer);
    }
}

# Understanding the solution

The first step is to analyze the given String. The String has three **leading** spaces and three **trailing** spaces. There are only two capitalized letters, and the String is longer than six characters; hence the **required** String must be *extracted*.


Line 6
* Using the **trim()** method, the leading and trailing *spaces* are removed from the given String. 
* Assign **answer** to this String to **save** the changes made to argument **text**.


Line 7
* This expression assigns an answer to the modified version of the *answer*.
* The **substring()** method extracts the required String from the given one. 
* The starting parameter is `0`, as it is inclusive. However, the end parameter is `6` as that is **not inclusive**.

Line 8
* This expression assigns an answer to the modified version of the *answer*.
* This uses the **toUpperCase()** method to convert all characters to upper case ones in the String chosen.

In this review, the solution of the challenge 'Finding the Right Words' from the previous lesson is provided.
