仅通过调用单个类来使用2类

Question

class merged(){


//i want to be able to use class sample1 and sample2 by just calling this merged class
} 

class sample1(){}
class sample2(){}

或者这样做不理想？能否请您建议我如何更有效地实施？

Answer 1

组成？

Class merged(){

sample1 s1 = new sample1();
sample1 s2 = new sample2();

void doSomething1()
{
s1.dosomething();
}

void doSomething2()
{
s2.dosomething();
}

}
