What fonts are there in java

java has five logical fonts, which are: 1. Serif is serif; 2. [Sans-serif] is sans serif; 3. Monospaced is equal width; 4. Dialog is dialog box; 5. DialogInput is dialog box input.

Java's fonts are:

Java defines five logical fonts: Serif (serif), Sans-serif (no serif), Monospaced (monospaced), Dialog (dialog box), DialogInput (dialog input). Each font corresponds to four font styles: plain (flat), bold (bold), italic (italic), bolditalic (bold italic).

We can select logical fonts, sizes and colors, but we cannot select specific physical fonts. The corresponding physical fonts need to be set in the JRE font configuration file.

The main factors that affect graphic fonts are: current language code page, database character set, installed fonts and font configuration files

1. Language code page

The language code page is the current language environment. In Linux and UNIX environments, use the .profile file to configure it. Under Windows, you need to view the active code. page settings, type: chcp, a message similar to the following appears: Active code page: 437, to change the active code page to 850 (multilingual), type: chcp 850, if the specified code page is invalid, it will The following error message appears: Invalid code page. The following table lists all supported code pages and their countries (regions) or languages:

2. Use the specific database character set

The command can view the character set used by the current database instance and set the character set. (Note: After setting under the Windows command line, you need to exit and re-run another command line session to take effect). The following table shows various commonly used language code pages and character sets (different character sets use different physical fonts in the font configuration file):

3. Installed fonts

On the Windows platform, you can view the installed fonts in "Control Panel->Fonts". In addition, JRE also comes with several fonts in %JAVAHOME%/lib/fonts.

Note: %JAVAHOME% refers to the root directory of Java installation.

4. Font configuration file

Java can configure fonts in JRE. Font configuration files are not consistent under different versions of JRE. Similarly, you can use the %JAVAHOME%/bin/java -version command to view the specific JRE version installed. You can check the configuration method in detail on the sun official website: please go to Java SE first, select the Technologies tab, you can find the "Intl Support" window in the overall framework diagram, and search for "The Font Configuration Files" after entering.
