Commands and code blocks

"Let me tell you about commands (statements) and code blocks. This is really simple stuff. A method body consists of commands, or statements. Each command ends in a semicolon."

String s = "Name";

System.out.println(1234);

return a + b * c;

throw new RuntimeException();

;

"A code block consists of several commands combined using curly brackets. A method body is a code block."

{}

{
     throw new RuntimeException();
 }

{
     return null;
 }

{
     System.out.println(23);
     System.out.println(1);
     System.out.println(14);
 }

"The following rule is valid in almost any situation: wherever you can write one command, you can also write a code block. We will see examples of this in subsequent tasks."
