Java 8过滤字符串

public class StringFilterExample {
    public static void main(String[] args) {
        List<String> strings = Arrays.asList("apple", "banana", "cherry", "date", "elderberry");

        // 过滤出长度大于5的字符串
        List<String> filteredStrings = strings.stream()
                                           .filter(s -> s.length() > 5)
                                           .collect(Collectors.toList());

        System.out.println(filteredStrings); // 输出: [banana, cherry, elderberry]
    }
}

List<String> strings = Arrays.asList("apple", "banana", "cherry", "date", "elderberry");

// 打印原始数据集
System.out.println(strings); // 输出: [apple, banana, cherry, date, elderberry]

// 过滤出长度大于5的字符串
List<String> filteredStrings = strings.stream()
                                       .filter(s -> s.length() > 5)
                                       .collect(Collectors.toList());

System.out.println(filteredStrings); // 输出: [banana, cherry, elderberry]

List<String> strings = Arrays.asList("apple", "banana", "cherry", "date", "elderberry");

// 使用并行流过滤字符串
List<String> filteredStringsParallel = strings.parallelStream()
                                           .filter(s -> s.length() > 5)
                                           .collect(Collectors.toList());

System.out.println(filteredStringsParallel); // 输出: [banana, cherry, elderberry]
