java - 将 Class 对象传递给方法

Question

我正在尝试将 Class 传递给方法。 Class 随着程序运行而变化，因此我想在整个程序中重用相同的方法，而不是在整个 resetWords() 方法中调用相同的函数。

这是我陷入困境的地方:

private void getWords(Class c) {
    singles = c.getSingleSyllables();
    doubles = c.getDoubleSyllables();
    triples = c.getTripleSyllables();
    quadruples = c.getQuadrupleSyllables();
    quintuples = c.getQuintupleSyllables();
}

private void resetWords() {
    if (generated.equals("SOMETHING")) {
        Something c = new Something();
        getWords(c);
    }
    else if (generated.equals("ANOTHER")) {
        Another c = new Another();
        getWords(c);
    }
}

Answer 1

我认为您正在寻找的是一个界面。您应该声明这样的接口(interface):

public interface Passable
{
    public List<String> getSingleSyllables();
    public List<String> getDoubleSyllables();
    // ...
}

然后，让 Something 和 Another 实现它们:

public class Something implements Passable
{
    // method declarations
}

现在，将您的方法更改为:

private void getWords (Passable c) {
    singles = c.getSingleSyllables();
    doubles = c.getDoubleSyllables();
    triples = c.getTripleSyllables();
    quadruples = c.getQuadrupleSyllables();
    quintuples = c.getQuintupleSyllables();
}
