使用泛型将Java中的Set转换为Stream的程序
假设以下是我们的Set-
Set<Integer> set = new HashSet<>(Arrays.asList(15, 40, 60, 90, 120, 150, 200));
现在，创建一种将上述设置转换为流的方法。
Stream<Integer>streamOfInteger = convertSet(set);
方法-
private static <T> Stream<T> convertSet(Set<T> set) {
return set.stream();
}示例
以下是使用泛型将Java中的Set转换为Stream的程序-
import java.util.*;
import java.util.stream.*;
import java.util.function.*;
public class Demo {
private static <T> Stream<T> convertSet(Set<T> set) {
return set.stream();
}
public static void main(String args[]) {
Set<Integer> set = new HashSet<>(Arrays.asList(15, 40, 60, 90, 120, 150, 200));
System.out.println("Set = " + set);
Stream<Integer>streamOfInteger = convertSet(set);
System.out.println("Stream (Set to Stream) = "+ Arrays.toString(streamOfInteger.toArray()));
}
}输出结果
Set = [150, 40, 120, 200, 90, 60, 15] Stream (Set to Stream) = [150, 40, 120, 200, 90, 60, 15
