Java使用Catcher捕获异常的实现

try {
    doSomething();
} catch (Exception e) {
    e.printStackTrace();
    //or Logger.d("error:" + e.getMessage());
}

try {
    doSomething();
} catch (Exception ignore) {
}

capture IOException 
    from () -> {
    }
    to handleIOException

Catcher.capture(IllegalAccessException.class)
        .from(() -> {
            //do something
            throw new Exception("kdsfkj");
        }).to(Main::onFailed);
//或
Catcher.capture(IllegalAccessException.class, IOException.class)
        .from(() -> {
            //do something
            throw new Exception("kdsfkj");
        })
        .to(e -> {
            //handle exception
        });

public class Catcher {
    List<Class<?>> classes = new LinkedList<>();
    private Action action;
    private  <T extends Exception> Catcher(List<Class<? extends T>> list) {
        classes.addAll(list);
    }
    @SafeVarargs
    public static <T extends Exception> Catcher capture(Class<? extends T>... classes){
        List<Class<? extends T>> list = Arrays.asList(classes);
        return new Catcher(list);
    }
    public Catcher from(Action action){
        this.action = action;
        return this;
    }
    public void to(Consumer<Exception> exceptionConsumer){
        try {
            action.run();
        } catch (Exception e) {
            for(Class<?> mClass : classes){
                if(mClass.isInstance(e)){
                    exceptionConsumer.accept(e);
                    return;
                }
            }
            throw new IllegalStateException(e);
        }
    }
    public interface Action{
        void run() throws Exception;
