//条件判断你写错了

package com.xt;

import java.util.Scanner;

public class Test {
public static void main(String[] args) {

    Scanner input = new Scanner(System.in);
    System.out.print("输入成绩：");
    int score = input.nextInt();
    if (score >= 90) {
        System.out.print("输入性别：");
        Scanner gd = new Scanner(System.in);
        char gender = gd.next().charAt(0);
        if (gender == '男') {
            System.out.println("进入男子组决赛");
        } else if (gender == '女') {
            System.out.println("进入女子组决赛");
        } else {
            System.out.println("未进入决赛");
        }
    }
}
