例子
下面的例子显示java.lang.Character.Subset.hashCode()方法的使用。
package com.yiibai import java.lang.* public class CharacterSubsetDemo extends Character.Subset { // constructor of super class CharacterSubsetDemo(String s) { super(s) } public static void main(String[] args) { CharacterSubsetDemo obj1 = new CharacterSubsetDemo("admin") CharacterSubsetDemo obj2 = new CharacterSubsetDemo("webmaster") CharacterSubsetDemo obj3 = new CharacterSubsetDemo("administrator") // returns a hash code value int retval = obj1.hashCode() System.out.println("Hash code of Object " + obj1 + " = " + retval) retval = obj2.hashCode() System.out.println("Hash code of Object " + obj2 + " = " + retval) retval = obj3.hashCode() System.out.println("Hash code of Object " + obj3 + " = " + retval) } }
让我们来编译和运行上面的程序，这将产生以下结果：
Hash code of Object admin = 1414159026 Hash code of Object webmaster = 1569228633 Hash code of Object administrator = 778966024
