Equal 的使用举例

public class packageTest
{

 /**
  * @param args
  */
 public static void main(String[] args)
 {
  // TODO Auto-generated method stub
  
  Employee harry1 = new Employee("xiongxinfang",10000,1987,10,1);
  Employee harry2 = harry1;
  Employee harry3 = new Employee("xiongxinfang",10000,1987,10,1);
  Employee bob  = new Employee("hello ",18464,1987,10,10);
  
  System.out.println("harry1 ==  harry2 :" + (harry1 == harry2));
  System.out.println("harry1 ==  harry3 :" + (harry1 == harry3));
  
  System.out.println("harry1.equal(harry3)" + harry1.equals(harry3));
  
  System.out.println("harry1.equal(bob)" + harry1.equals(bob));
  
  System.out.println("bob toString" + bob.toString());
  System.out.println("bob hashcode" + bob.hashCode());
  
  
  System.out.println();
