该程序不允许您读取用户输入

package out.production.javaworks;

import java.util.Scanner;

public class Person {

String name;
int age;
String gender;

public void printText(String str) {
    System.out.println(str);
}
public Person() {
}

public Person(String name, int age, String gender) {
    this.name = name;
    this.age = age;
    this.gender  = gender;
}

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

    Person project = new Person();
    Person people1 = new Person("", 0, "");

    System.out.println("Введите Ваше имя:");
    people1.name = scanner.nextLine();
    System.out.println("Введите Ваш возраст:");
    people1.age = scanner.nextInt();
    System.out.println("Введите Ваш пол (гендер):");
    people1.gender = scanner.nextLine();

    System.out.println("Привет, " + people1.name + "!");
 }
}

在“输入您的性别（性别）：”行之后我没有时间输入数据并执行以下指令（文本输出）这是什么原因？

    这是因为它nextInt不读取行尾。

    ...
System.out.println("Введите Ваш возраст:");
people1.age = scanner.nextInt();
scanner.nextLine();
System.out.println("Введите Ваш пол (гендер):");
people1.gender = scanner.nextLine();
