为什么说我的last没有初始化
public class HelloWorld {
public static void main(String[] args) {
int score = 94;
String sex = "女";
String last;
if (score>80){
if (sex.equals("女")){
last="进入女子组决赛";
}else{
last="进入男子组决赛";
}
}
System.out.println(last);运行失败
HelloWorld.java:13: error: variable last might not have been initialized
System.out.println(last);
^
1 error
