Arrays 是在java.util包下的一个工具类,里面定义了对数组的一些操作方法。 包含用来操作数组(比如排序和搜索)的各种方法。 包含一个允许将数组作为列表来查看的静态工厂。 除非特别注明,否则如果指定数组引用为 null,则此类中的方法都会抛出 NullPointerException 常用方法介绍 asList() 返回一个受指定数组支持的固定...
步骤1 : 数组复制 与使用System.arraycopy进行数组复制类似的, Arrays提供了一个copyOfRange方法进行数组复制。 不同的是System.arraycopy,需要事先准备好目标数组,并分配长度。copyOfRange 只需要源数组就就可以了,通过返回值,就能够得到目标数组了。 除此之外,需要注意的是 copyOfRange 的第3个参数,表示源数组的...

The easiest way to reverse the array is to use the existing APIs built for this very purpose.Collections.reverse()method is such an API. This method reverses the elements in a list, so we must convert the array into a list first by usingjava.util.Arrays.asList(array)and then reverse th...
