How to set Chinese in java programming software

In Java programming, setting Chinese mainly involves two aspects: the character encoding of the source code file and the character encoding when the program is running. Some suggestions for setting Chinese: 1. Make sure that the Java source code file uses UTF-8 character encoding, because UTF-8 supports multi-language character sets, including Chinese. In most modern integrated development environments (IDEs), the default is UTF-8, but it can be checked and confirmed in the IDE settings; 2. Ensure that the Chinese character set is correctly handled in the program, especially for input and output operations .

In Java programming, setting Chinese mainly involves two aspects: the character encoding of the source code file and the character encoding when the program is running. Here are some suggestions for setting up Chinese:

1. Character encoding of source code files:

Make sure your Java source code files use UTF-8 character encoding because UTF-8 supports multi-language character sets, including Chinese.

In most modern integrated development environments (IDEs), UTF-8 is the default, but you can check and confirm in the IDE's settings.

2. Character encoding when the program is running:

Ensure that the Chinese character set is processed correctly in the program, especially It is for input and output operations. Here are some suggestions:

2.1 Console output:

When using System.out.println() or System.out.print( ) When outputting Chinese, make sure the console uses the correct character encoding. You can set it at the entrance of the program:

##

public class Main {
    public static void main(String[] args) {
        // 设置控制台输出编码为UTF-8
        System.setProperty("file.encoding", "UTF-8");
        // 你的其他代码
    }
}

2.2 File reading and writing:

When using FileInputStream, FileOutputStream, BufferedReader, BufferedWriter, etc. to read and write files, make sure to use the correct character encoding. For example:

// 读取文件
try (BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream("file.txt"), "UTF-8"))) {
    // 读取文件的代码
} catch (IOException e) {
    e.printStackTrace();
}
// 写入文件
try (BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("file.txt"), "UTF-8"))) {
    // 写入文件的代码
} catch (IOException e) {
    e.printStackTrace();
}

2.3 String processing:

When processing strings, Make sure to use the correct character encoding for conversion, for example:

// 将字节数组转换为字符串
byte[] bytes = ...; // 从文件或网络中读取的字节数组
String content = new String(bytes, "UTF-8");
// 将字符串转换为字节数组
String content = ...; // 要写入文件或发送的字符串
byte[] bytes = content.getBytes("UTF-8");

With these settings, you can ensure that Chinese is handled correctly in Java programming characters to avoid problems such as garbled characters.
