1. Parameters of the `println()` method

A method body consists of commands. You could even say that a method is a group of commands that has been given a name, i.e. the method name. Either perspective is accurate.

There are different kinds of commands. The Java language has a command for every occasion. Each command defines some specific action. A semicolon goes at the end of each command.

Examples of commands:

Command	Description (what it does)
`System.out.println(1);`	Displays a number on the screen: `1`
`System.out.println("Amigo");`	Displays text on the screen: `Amigo`
`System.out.println("Risha & Amigo");`	Displays text on the screen: `Risha & Amigo`

Actually, this is just one command — System.out.println. The arguments passed to it are contained in the parentheses. Depending on the value of the parameters, a command can perform various actions. This is super convenient.

Important:

In Java, size matters in terms whether the letters in a method are uppercase or lowercase. The System.out.println() command will work, but system.out.println() will not.

If you want to display text, you need to mark it on both sides with double quotes.

A single quote looks like this ', and a double quote looks like this ". A double quote is not two single quotes: please don't get confused by that.

The double quotes symbol is the one next to the Enter key.

2. Differences between `println()` and `print()`

There are two variations of the command for screen output: System.out.println() and System.out.print()

If you write the System.out.println() command several times, each time the passed text will be displayed on a new line. If you use System.out.print(), then the text will be displayed on the same line. Example:

Commands What will be displayed

System.out.println("Amigo");
System.out.println("IsThe");
System.out.println("Best");

Amigo
IsThe
Best

System.out.print("Amigo");
System.out.println("IsThe");
System.out.print("Best");

AmigoIsThe
Best

System.out.print("Amigo");
System.out.print("IsThe");
System.out.print("Best");

AmigoIsTheBest

A small note. The println() command does not display the text on a new line. Instead, it displays text on the current line — the next text that is displayed will appear on a new line.

The println() command displays text and then adds a special invisible newline character. As a result, the next text will be displayed at the beginning of a new line.

This is what the fully written program will look like, along with a declaration of an Amigo class and a main method. Keep your eyes on the screen:

public class Amigo
{
   public static void main (String[] args)
   {
      System.out.print("Amigo ");
      System.out.print("The ");
      System.out.print("Best");
   }
}
