Class Modifier

    java.lang.Object
      java.lang.reflect.Modifier

public class Modifier
extends Object

The Modifier class provides `static` methods and constants to decode class and member access modifiers. The sets of modifiers are represented as integers with distinct bit positions representing different modifiers. The values for the constants representing the modifiers are taken from The JavaTM Virtual Machine Specification, Second edition tables 4.1, 4.4, 4.5, and 4.7.

  `Class.getModifiers()`, `Member.getModifiers()`

    `true` if `mod` includes the `strictfp` modifier; `false` otherwise.

### toString

    public static String toString(int mod)

  Return a string describing the access modifier flags in the specified modifier. For example:

  >         public final synchronized strictfp

  The modifier names are returned in an order consistent with the suggested modifier orderings given in The Java Language Specification, Second Edition sections §8.1.1, §8.3.1, §8.4.3, §8.8.3, and §9.1.1. The full modifier ordering used by this method is:

  > `public protected private abstract static final transient volatile synchronized native strictfp interface`

  The `interface` modifier discussed in this class is not a true modifier in the Java language and it appears after all other modifiers listed by this method. This method may return a string of modifiers that are not valid modifiers of a Java entity; in other words, no checking is done on the possible validity of the combination of modifiers represented by the input.

  Parameters:
    `mod` - a set of modifers
  Returns:
    a string representation of the set of modifers represented by `mod`
