示例

下面的例子展示了 java.lang.Character.Subset.hashCode() 方法的使用。

package com.tutorialspoint;

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);
   }
} 

让我们编译并运行上面的程序，这将产生下面的结果 −

Hash code of Object admin = 1704856573
Hash code of Object webmaster = 705927765
Hash code of Object administrator = 366712642
