how to write a react page to show a picture with text

Here's a basic example of how to write a React component to display an image with text:

javascriptCopy codeimportReactfrom"react";

constImageWithText = ({ imageSrc, altText, text }) => {

return (

<div><imgsrc={imageSrc}alt={altText} /><p>{text}</p></div>

);

};

exportdefaultImageWithText;

In the code above, we import the React library and create a functional component called ImageWithText. This component takes in three props: imageSrc, altText, and text.

The component returns a div that contains an img element with the source set to imageSrc and the alt text set to altText. The component also contains a p element that displays the text prop.

To use this component in another part of your application, you would import it and pass in the relevant props:

javascriptCopy codeimportImageWithTextfrom"./ImageWithText";

constApp = () => {

return (

<div><ImageWithTextimageSrc="image.jpg"altText="A beautiful image"text="This is the accompanying text"

/></div>

);

};

exportdefaultApp;

In this example, we import the ImageWithText component and use it inside a functional component called App. The App component returns a div that contains the ImageWithText component with the relevant props passed in.

编写一个java后台程序，可以返回当前时间

Here's an example of how to write a simple Java program to return the current date and time:

javaCopy codeimport java.time.LocalDateTime;

import java.time.format.DateTimeFormatter;

publicclassCurrentDateTime {

publicstaticvoidmain(String[] args) {

LocalDateTimenow= LocalDateTime.now();

DateTimeFormatterformatter= DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");

StringformattedDateTime= now.format(formatter);

System.out.println("The current date and time is: " formattedDateTime);

}

}

In the code above, we import the LocalDateTime and DateTimeFormatter classes from the java.time package.

In the main method, we create an instance of LocalDateTime using the now() method, which returns the current date and time.

Next, we create a DateTimeFormatter object using the ofPattern method, passing in the desired date and time format, yyyy-MM-dd HH:mm:ss.

We then use the format method to format the LocalDateTime object into the desired format, and store the result in a String variable called formattedDateTime.

Finally, we print the current date and time to the console using System.out.println().

how to write a video player used in android system

Here's an example of how to write a simple video player in Android:

1. Create a new project in Android Studio.

2. In the activity_main.xml file, add a VideoView element to the layout:

phpCopy code<RelativeLayoutxmlns:android=" http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"><VideoViewandroid:id="@ id/videoView"android:layout_width="match_parent"android:layout_height="match_parent" /></RelativeLayout>

3. In the MainActivity.java file, add the following code to play the video:

javaCopy codeimport android.net.Uri;

import android.os.Bundle;

import android.widget.MediaController;

import android.widget.VideoView;

import androidx.appcompat.app.AppCompatActivity;

publicclassMainActivityextendsAppCompatActivity {

@OverrideprotectedvoidonCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

VideoViewvideoView= findViewById(R.id.videoView);

StringvideoPath="android.resource://" getPackageName() "/" R.raw.video;

Uriuri= Uri.parse(videoPath);

videoView.setVideoURI(uri);

MediaControllermediaController=newMediaController(this);

videoView.setMediaController(mediaController);

mediaController.setAnchorView(videoView);

}

}

In the code above, we create a VideoView object in the onCreate method and set the video resource using the setVideoURI method, passing in a Uri object that points to the video file.

We then create a MediaController object and set it as the media controller for the VideoView using the setMediaController method.

Finally, we set the VideoView as the anchor view for the media controller using the setAnchorView method.

Note: You will need to add a video file (e.g. video.mp4) to the res/raw directory of your project and reference it in the code by its resource ID (e.g. R.raw.video).

how to write a native c program project

Here's an example of how to write a simple "Hello, World!" program in C:

4. Create a new file with a .c extension, such as hello.c.

5. Enter the following code into the file:

cCopy code#include<stdio.h>intmain() {

printf("Hello, World!\n");

return0;

}

6. Open a terminal or command prompt and navigate to the directory where the hello.c file is located.

7. Compile the program using the gcc compiler:

Copy codegcc -o hello hello.c

The -o option is used to specify the name of the output file, in this case hello.

8. Run the program by executing the compiled binary file:

bashCopy code./hello

You should see the following output:

Copy codeHello, World!

This program includes the stdio.h header file, which provides the printf function for printing text to the console.

The main function is the entry point of the program and is where the code is executed. In this example, we use printf to print the message "Hello, World!" to the console, followed by a newline character (\n).

Finally, the return 0 statement at the end of the main function indicates that the program has executed successfully.
