1.String s1 = new String("hello"); 2.String s2 = new String("hello"); 3.System.out.println(s1==s2):
1.String s1 = new String("hello"); 2.String s2 = new String("hello"); 3.System.out.println(s1==s2):

1.String s1 = new String("hello"); 2.String s2 = new String("hello"); 3.System.out.println(s1==s2):
呃,什么问题呢?这几句话输出的结果是：false.s1,s2指向的对象内容相同,但是本身是不同的.如果使用s1.equals(s2),则是true.
