When you want to use code blocks, put 4 spaces on the top so that it will be recognized as a code block.

Another way to recognize the text as a code block is to surround the relevant text with " ``` ".When you want to use the code block style for part of a sentence, surround it with " ` " . It will be recognized as inline code.

Example

   package helloworld;

   public class Hello {

       public static void main(String[] args) {

           System.out.println("Hello World");

       }

   }

```

package helloworld;

public class Hello {

   public static void main(String[] args) {

       System.out.println("Hello World");

   }

}

```

`inline code`

Result
