Java 中将整数 Set 转换为字符串 Set 的程序

假设我们的整数 Set 为 -1
Set<Integer> setInteger = new HashSet<>(Arrays.asList(100, 200, 300, 500, 600, 800, 1000));
现在，我们将其转换为字符串 Set -1
Set<String> setStr = setInteger.stream().map(String::valueOf).collect(Collectors.toSet());
示例
以下是 Java 中将整数集合转换为字符串集合的程序 −
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);
}
}
输出
Set = [800, 100, 500, 200, 600, 1000, 300] New Set (String) = [100, 200, 300, 500, 600, 800, 1000]
