static methods for creating the standard set of Predicate objects.

Method Summary

All Methods Static Methods Concrete Methods
Modifier and Type	Method and Description
`static <T> Predicate<T>`	`alwaysFalse()` Returns a Predicate that always evaluates to false.
`static <T> Predicate<T>`	`alwaysTrue()` Returns a Predicate that always evaluates to true.
`static <T> Predicate<T>`	`and(java.util.Collection<Predicate<? super T>> components)` Returns a Predicate that evaluates to true iff each of its components evaluates to true.
`static <T> Predicate<T>`	`and(Predicate<? super T>... components)` Returns a Predicate that evaluates to true iff each of its components evaluates to true.
`static <T> Predicate<T>`	`not(Predicate<? super T> predicate)` Returns a Predicate that evaluates to true iff the given Predicate evaluates to false.
`static <T> Predicate<T>`	`or(Predicate<? super T>... components)` Returns a Predicate that evaluates to true iff any one of its components evaluates to true.

- Method Detail
  - alwaysTrue
```
public static <T> Predicate<T> alwaysTrue()
```
    Returns a Predicate that always evaluates to true.
  - alwaysFalse
```
public static <T> Predicate<T> alwaysFalse()
```
    Returns a Predicate that always evaluates to false.
  - not
```
public static <T> Predicate<T> not(Predicate<? super T> predicate)
```
    Returns a Predicate that evaluates to true iff the given Predicate evaluates to false.
  - and
```
public static <T> Predicate<T> and(Predicate<? super T>... components)
```
    Returns a Predicate that evaluates to true iff each of its components evaluates to true. The components are evaluated in order, and evaluation will be "short-circuited" as soon as the answer is determined. Does not defensively copy the array passed in, so future changes to it will alter the behavior of this Predicate.
  - and
```
public static <T> Predicate<T> and(java.util.Collection<Predicate<? super T>> components)
```
    Returns a Predicate that evaluates to true iff each of its components evaluates to true. The components are evaluated in order, and evaluation will be "short-circuited" as soon as the answer is determined. Does not defensively copy the array passed in, so future changes to it will alter the behavior of this Predicate.
  - or
```
public static <T> Predicate<T> or(Predicate<? super T>... components)
```
    Returns a Predicate that evaluates to true iff any one of its components evaluates to true. The components are evaluated in order, and evaluation will be "short-circuited" as soon as the answer is determined. Does not defensively copy the array passed in, so future changes to it will alter the behavior of this Predicate.
