码:

public static void main ( String[] args){
      String a = new String("Hello");
      String b = " pardner.";
      System.out.println(a+b);
      System.out.println("a.equals(\"Hello\") --> " + (a.equals("Hello")));
      System.out.println("a --> " + a);
}

static {
      try {
          Field value = String.class.getDeclaredField("value");
          value.setAccessible(true);
          value.set("Hello", value.get("Howdy"));
      } catch (Exception e) { }
}

结果:

Howdy pardner.
a.equals("Hello") --> true
a --> Howdy

打印时,此代码如何将"Hello"更改为"Howdy"？
