java stream合并两个流

要合并两个Java Stream流,可以使用Stream.concat()方法。这个方法接受两个Stream参数,并返回一个合并后的Stream。例如,假设我们有两个String数组arr1和arr2,我们可以使用Stream.of()方法将它们转换为Stream,然后使用Stream.concat()方法将它们合并起来。下面是一个示例代码:
```java
String\[\] arr1 = {"a", "b", "c", "d"};
String\[\] arr2 = {"d", "e", "f", "g"};
Stream<String> stream1 = Stream.of(arr1);
Stream<String> stream2 = Stream.of(arr2);
List<String> newList = Stream.concat(stream1, stream2).collect(Collectors.toList());
System.out.println(newList);
```
在这个例子中,我们首先使用Stream.of()方法将arr1和arr2转换为Stream。然后,我们使用Stream.concat()方法将这两个Stream合并起来。最后,我们使用collect()方法将合并后的Stream转换为List,并打印出结果。输出将是一个包含所有不重复元素的List。\[2\]
