Do Capillaries Disappear

java.util.Objects the new library of Java 7! The history of linux

The truth is that many do not like (to be resistance to change), I think it robs the objects work, for me this feature should be an Object or otherwise, do not know. Beyond my humble opinion was necessary, we always had to write a util to do things that makes this library hours.

Here are some examples:

showFoo public void (Foo foo) {Foo foo2 = new Foo ();
/ / lot of code

if (foo.equals (foo2)) {System.out
. println ("Two Men");

} else {System.out.println ("And a Half ");
}}

 
 
 
 NullPointer 
 This can see how we solve it with Objects: 
 
 
 showFoo public void (Foo foo) {
 
 Foo foo2 = new Foo (); 
 
 / / 
 

lot of code if (Objects.equals (foo, foo2)) {
System.out.println ("Two Men");

} else {System.out.println ("And a Half");}

} 
 
 
 
 
 We can make hash with Objects, which will be of org.apache.commons.lang.builder.HashCodeBuilder 
 
 
 @ Override public int hashCode () {return 
 Objects.hash (name, age, job);} 
 
 
 
 

We can check that an object is null public void


showFoo (Foo foo) {

 this.bar = Objects.requireNonNull (foo);} 
 
 
 
 

We take take the toString if not null, and otherwise return a value: return


Objects.toString (foo, "Foo is Empty");

 
 
 
 Interesting no? they think the new library?
