Tutorial #11: Modifier Types

• 
  
• 
  
• Visible to the package, the default. No modifiers are needed.

• Visible to the class only (private).

• Visible to the world (public).

• Visible to the package and all sub-classes (protected).

To use a modifier, you include its keyword in the definition of a class, method, or variable. The modifier precedes the rest of the statement.

public class className {
   // ...
}

private boolean myFlag;
static final double weeks = 9.5;
protected static final int BOXWIDTH = 42;

public static void main(String[] arguments) {
   // body of method
}
