For reverse sorting the array, useComparator.reverseOrder(). // Unsorted string array String[] strArray = {"Alex","Charles","Dean","Amanda","Brian"}; // Sorting the strings strArray = Stream.of(strArray) .sorted() .toArray(String[]::new); // Sorted array System.out.println("Sorte...
Suppose x is a list known to contain only strings. The following code can be used to dump the list into a newly allocated array of String: String[] y = x.toArray(newString[0]); 1 Note that toArray(new Object[0]) is identical in function to toArray() Specified by: toArray in i...

/String[] array = (String[]) arrayList.toArray();for (String s : array) {System.out.println(s);}/ } /** 方式二(分写): String[] strings = new String[list.size()]; list.toArray(strings); */ @Test public void listToArrayTest2_1(){ ...

通过Stream.of() 创建:我们可以使用Stream.of()方法直接将一组元素转换为 Stream 对象。例如: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 Stream<Integer>stream=Stream.of(1,2,3,4,5); 通过Stream.builder() 创建:如果我们不确定要添加多少个元素到 Stream 中,可以使用Stream.builder()创建一个 Str...
for(type element:array){System.out.println(element);} 注: foreach 语句为数组或对象集合中的每个元素重复一个嵌入语句组。foreach 语句用于循环访问集合以获取所需信息,但不应用于更改集合内容以避免产生不可预知的副作用。 因此不要对foreach的循环变量赋值。 例如: ...
