Array工具类的所有方法如下: (可以改变或获取数据对应下标的值)===结合apache的Arrayutils可以满足对数组的基本操作 例如: packageloader;importjava.lang.reflect.Array;publicclassConstants {publicstaticvoidmain(String[] args) { String[] strings= { "1", "2"}; System.out.println(strings.getClass().getCo...
比如有一个数组是 String[] array = [ 'a', 'b', 'c' ],我希望把该数组中每个元素直接用 ' - ' 来拼接,得到 ”a-b-c",那么应该如何实现呢? 最传统的办法就是: String result = array.get(0); for(int i = 1; i < array.size(); i++) { ...

palindrome.getChars(0, len, tempCharArray, 0); Concatenating Strings TheStringclass includes a method for concatenating two strings: string1.concat(string2); This returns a new string that is string1 with string2 added to it at the end. ...
由数组创建流 Java8 中的 Arrays 的静态方法 stream() 可以获取数组流 :static Stream stream(T[] array) : 返回一个流 重载形式,能够处理对应基本类型的数组IntStream/LongStream/DoubleStream : 由值创建流 可以使用静态方法 Stream.of(), 通过显示值创建一个流,它可以接收任意数量的参数:public static Stream...
