Program to convert Set of Integer to Set of String in Java
Let’s say the following is our Set of Integer −
Set<Integer> setInteger = new HashSet<>(Arrays.asList(100, 200, 300, 500, 600, 800, 1000));
Now, let us convert this to Set of String −
Set<String> setStr = setInteger.stream().map(String::valueOf).collect(Collectors.toSet());
Example
Following is the program to convert set of Integer to Set of String in Java −
import java.util.*;
import java.util.stream.*;
import java.util.function.Function;
public class Demo {
public static void main(String args[]) {
Set<Integer> setInteger = new HashSet<>(Arrays.asList(100, 200, 300, 500, 600, 800, 1000));
System.out.println("Set = " + setInteger);
Set<String> setStr = setInteger.stream().map(String::valueOf).collect(Collectors.toSet());
System.out.println("New Set (String) = " + setStr);
}
}Output
Set = [800, 100, 500, 200, 600, 1000, 300] New Set (String) = [100, 200, 300, 500, 600, 800, 1000]
