Question

错误：变量a，b，h2和h1可能尚未初始化。就像我说的，我是java的新手，只有3天，真的不明白为什么这不会工作...而且，类口袋妖怪我不会费心发布ebcasue它工作正常，错误真的没什么做它。

import java.util.Scanner;

public class Simplemon extends Pokemon {
    Simplemon(int health, int strength, int speed, int type) {
        super(health, strength, speed, type);

    }
}

您需要将变量设置为某个初始值。

String a = "";
String b = "";
int h1 = "";
int h2 = "";

最后4行中的错误（java新手，我会理解我不明白的错误，哪些错误）
