String变量被初始化后,长度和内容都不可变,每次对String的操作都会生成新的String对象,不仅效率低,而且耗费大量内存空间;对于String str = new String(“abc”),实际上创建了两个String对象,一个是”abc”对象,存储在常量空间中(常量池),一个是使用new关键字为对象str申请的空间。 Integer i1 = new Integer(1)...

The keys are not integer keys. They can be characters, integers, strings, etc. — basically, any Ruby object type. The keys are not ordered. So, you couldn’t say thatais “first” or that it “comes before”bin the example above, because Ruby does not look at the order of keys in...
