Program to convert a Set to Stream in Java using Generics
Let’s say the following is our Set −
Set<Integer> set = new HashSet<>(Arrays.asList(15, 40, 60, 90, 120, 150, 200));
Now, create a method to convert the above set to stream.
Stream<Integer>streamOfInteger = convertSet(set);
The method −
private static <T> Stream<T> convertSet(Set<T> set) {
return set.stream();
}Example
Following is the program to convert a Set to Stream in Java using Generics −
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()));
}
}Output
Set = [150, 40, 120, 200, 90, 60, 15] Stream (Set to Stream) = [150, 40, 120, 200, 90, 60, 15
