如何在Java中跳过输入行

import java.util.Scanner;

public class SkipInputLine {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        System.out.println("请输入第一行内容：");
        String line1 = scanner.nextLine();

        System.out.println("请输入第二行内容：");
        String line2 = scanner.nextLine();

        // 跳过输入行
        scanner.nextLine();

        System.out.println("请输入第四行内容：");
        String line4 = scanner.nextLine();

        System.out.println("第一行内容：" + line1);
        System.out.println("第二行内容：" + line2);
        System.out.println("第四行内容：" + line4);

        scanner.close();
    }
}
