Implementation note: All basic operations execute in constant time. They are likely (though not guaranteed) to be faster than their HashMap counterparts. This class is a member of the Java Collections Framework. Added in 1.5. Java documentation for java.util.EnumMap....
我们来看WithoutHashCode.java这个例子。 在其中的第2到第18行,我们定义了一个Key类;在其中的第3行定义了唯一的一个属性id。当前我们先注释掉第9行的equals方法和第16行的hashCode方法。 1 import java.util.HashMap; 2 class Key { 3 private Integer id; 4 public Integer getId() 5 {return id; } 6...

Keys and values in a HashMap are actually objects. In the examples above, we used objects of type "String". Remember that a String in Java is an object (not a primitive type). To use other types, such as int, you must specify an equivalentwrapper class:Integer. For other primitive ty...
