1. 解释什么是Comparator以及其主要用途 Comparator是Java中的一个接口,位于java.util包下。它主要用于定义对象之间的比较规则,即当需要比较两个对象时,可以提供一个Comparator实例来告诉Java如何进行比较。Comparator的主要用途包括但不限于: 对集合(如List、Set)中的元素进行排序。 作为某些集合(如TreeSet、TreeMap)的...

17. 18. 19. 20. 21. 代码中Person类实现了Comparable接口,它是Comparable接口的实现类,按照属性age定义了Person类对象之间的一种“序”。但Person类并未对equals方法进行重写,直接继承了父类Object的equals方法。我们来测试一下: package main.compare;
17.A threshold comparator with hysteresis as defined in claim 14, wherein the coupling circuit comprises a multiplexer and a timing pulse generator, the multiplexer having an output coupled to the second input of the comparator circuit, a first input configured to receive the first reference voltag...
This paper explains the process of failure localization and mechanism analysis for a voltage comparator failure case. The output terminal of the voltage comparator is open circuit. The analysis adopted a series of analysis ideas such as non-destructive troubleshooting, internal positioning, and data st...
A novel current mode latched comparator designed for high speed and low-voltage, low-power applications is presented. It achieves a sampling speed of 200 Ms/s with 8 bit resolution and 3 V power supply. Its very low kickback noise makes if especially suitable for A/D converters with low ...
