接受两个参数的Consumer为什么叫BiConsumer?

这里的 i 是指 input吗? 那B又是指什么?这里BiConsumer是怎样命名的?

/**
 * Represents an operation that accepts two input arguments and returns no
 * result.  This is the two-arity specialization of {@link Consumer}.
 * Unlike most other functional interfaces, {@code BiConsumer} is expected
 * to operate via side-effects.
 *
 * <p>This is a <a href="package-summary.html">functional interface</a>
 * whose functional method is {@link #accept(Object, Object)}.
 *
 * @param <T> the type of the first argument to the operation
 * @param <U> the type of the second argument to the operation
 *
 * @see Consumer
 * @since 1.8
 */
@FunctionalInterface
public interface BiConsumer<T, U> {
    /**
     * Performs this operation on the given arguments.
     *
     * @param t the first input argument
     * @param u the second input argument
     */
    void accept(T t, U u);
}

回答：

Binary 的缩写，在这里的意思是‘和两件事有关’
