SpotBugs is an open-source static code analysis tool used in software development for bug detection. It scans bytecode (i.e., .class files) in your Java applications for bug patterns and ranks potential issues in terms of severity. SpotBugs can identify a variety of common coding mistakes, including null pointer dereferences, infinite recursive loops, bad uses of the Java libraries, and more.

The "data-" global attributes in HTML are used to store custom data private to the page or application. They provide a way to store extra information on HTML elements that JavaScript can later access. The "data-" attributes consist of a name (data-*) and a value. The name should be in lowercase and contain a hyphen (-) to separate words.

Yes, Java has an equivalent mechanism for asynchronous programming, similar to C#'s async/await. In Java, this is typically done using the CompletableFuture class, which was introduced in Java 8. CompletableFuture allows you to write non-blocking, asynchronous code using a more functional and fluent programming style.

先创建一个表：

@Test
void booleanArrayToIntArray() {
    boolean[] inputs = {true, false, false, false, false, false, false, true, false, false, false, false, false, false, false, false, false, false, false, false, false, false, false, false, false, false, false, false};
    int[] intArray = new int[inputs.length];
    IntStream.range(0, inputs.length).forEach(i -> intArray[i] = Boolean.compare(inputs[i], false));
    System.out.println(Arrays.toString(intArray));
}

The ReadDiscreteInputsRequest class is part of Modbus4J, and it's used to create a request for reading discrete input registers from a Modbus device.

As the founder of the republic, the president had many good qualities. Before coming to power, he was a generous lawyer. He was willing to selflessly help everyone who turned to him. He accepted no fee to offer legal guidance and opinions to those who were out of work or uneducated. Later, believing all mankind to be equal, he devoted himself to stopping the unfair anti-black laws. He set up the Black Youth League and was voted to be the leader. However, though he kept peaceful principles without violence and terror, his mean enemies still blew up his house and attacked his relatives, and he himself ouldn’t escape being sentenced to 30 years in prison.

Dirty water rose in wells and canals before the earthquake. But no one judged that an earthquake was coming. Suddenly, everything shook. It seemed as if the world was at an end. Millions of brick houses and a number of dams were destroyed. Railway tracks became useless bars. Pipes in mines burst and let out smelly steam. Huge cracks trapped cyclists everywhere.

My sister was fond of traveling. Ever since graduating, she had been determined to organize a trip to an old temple. Since transporting fare was expensive, she decided to use a bicycle to cycle there not caring about the disadvantages. Her stubborn attitude was always her shortcoming. Once she made up her mind to do something, no one could persuade her to change her mind. Finally, we gave in as usual though we preferred to take a train. After we prepared everything, including the schedule, reliable weather forecast and theinsurance, we began our trip.
