Java - Character hashCode() Method - The Java Character hashCode() method returns a hash code for the given Character. A hash code is a unique primitive integer that is assigned to every object in Java.
Java - Boolean hashCode(boolean value) Method - The Java Boolean hashCode() returns a hash code for a boolean value. This method is compatible with Boolean.hashCode().
Another less mathematical method is to convert each of the attributes to Strings, concatenate the Strings and use the hashCode of the resultant String. You need to be careful with how you convert the attributes to Strings with this one. In particular calling the toString method on the attribut...
实际使用中,equals()更像是用来判断两个对象是否等价,举个简单的例子:假如我们定义黑猫和白猫两个类,黑猫这个类中有两个属性String color = "black;"和String type = "cat";,白猫这个类中同样有两个属性String color = "white";和String type = "cat";,然后new出白猫...
If I for example use a string as a key and a person as a value and add this item to a hashtable this will never be any problem because it matters only when key is a instance. Is this right? Exactly. Values aren't checked for equality and their hashcodes aren't used. Jon Jun ...

obj1.compareTo(obj2)如果返回0,表示这两个对象相等,如果该方法返回一个正整数,表示obj1大于obj2如果该方法返回一个负整数,表示obj1小于obj2 所以需要使用TreeSet集合进行自然排序,元素必须实现Comparable接口,但是Java一些常用的类已经实现了该接口,例如:String Character Boolean Date Time ...
One easy way to do that is to rotate the current result by some number of bits, then XOR the current hash code with the current byte. Repeat until you reach the end of the string. Note that you generally do not want the rotation to be an even multiple of the byte size either. ...

Java.util.Arrays.hashCode(char[]) Method - The java.util.Arrays.hashCode(char[]) method returns a hash code based on the contents of the specified array. For any two char arrays a and b such that Arrays.equals(a, b), it is also the case that Arrays.hashC
