最常见的实现多重继承的方式，是implements interface1,interface2,interface3…

也可以通过多个内部类extends多个抽象类。

示例如下

public class Father {public int strong(){return 9;}
}public class Mother {public int kind(){return 8;}
}public class Son {/*** 内部类继承Father类*/class Father_1 extends Father{public int strong(){return super.strong() + 1;}}class Mother_1 extends  Mother{public int kind(){return super.kind() - 2;}}public int getStrong(){return new Father_1().strong();}public int getKind(){return new Mother_1().kind();}
}
