Statements & Blocks

• Statement
  -one or more lines of code terminated by a semicolon.
  -Example:System.out.println(“Hello world”);
  
• Block
  -is one or more statements bounded by an opening and closing curly braces that groups the statements as one unit.
  -Block statements can be nested indefinitely.
  -Any amount of white space is allowed.
  -Example:

-public static void main( String[] args )

{

System.out.println("Hello");

System.out.println("world”);

}

Coding Guidelines:

• In creating blocks, you can place the opening curly brace in line with the statement. For example:
  public static void main( String[] args ){
  or you can place the curly brace on the next line, like,
  public static void main( String[] args )‏
  {
  
• You should indent the next statements after the start of a block. For example:
  public static void main( String[] args ){
  System.out.println("Hello");
  System.out.println("world");
  }
