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.

class HelloWorld {
    public static void main( String args[] ) {
         //Defining all variables
         int int_number = 1000;
         char char_name = 'N';
         float float_number = 10.292f;
         double double_number = 0.00000000000512365123;
         boolean bool_accept = true;

         // Printing values of variables
         System.out.println("Value of Int is: ");
         System.out.println(String.valueOf(int_number));

         System.out.println("Value of Float is: ");
         System.out.println(String.valueOf(float_number));

         System.out.println("Value of Double is: ");
         System.out.println(String.valueOf(double_number));

         System.out.println("Value of Char is: ");
         System.out.println(String.valueOf(char_name));

         System.out.println("Value of Bool is: ");
         System.out.println(String.valueOf(bool_accept));   
    }
}

# Explanation
From lines `4` to `8`, all the variables were declared with their respective data types and values.

Then after every variable was printed using the `System.out.println` command.

In this review, the solution of the challenge 'Declaring Variables' is provided.
