}else{
System.out.println("加油"); //score <90时;输出加油
}
}

嵌套结构:
import java.util.*;
public class Test025 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("请输入成绩:");
int score = input.nextInt();
System.out.println("请输入性别:");
char gender = input.next().charAt(0);
if (score <= 10) {
if (gender == ‘男‘) {
System.out.println("进入男子决赛!");
} else if (gender == ‘女‘) {
System.out.println("进入女子决赛!");
}
} else {
System.out.println("淘汰!!");
}
}
