What are the java fonts?

Java fonts include: 1. Serif is serif; 2. [Sans-serif] is sans serif; 3. Monospaced is equal width; 4. Dialog is a dialog box; 5. DialogInput is a dialog box enter.

Java uses a method of mapping logical fonts to corresponding physical fonts on the running platform to handle the display of fonts.

Java defines five logical fonts: Serif (serif), Sans-serif (no serif), Monospaced (equal width), Dialog (dialog box), DialogInput ( dialog box 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

Language code page For the current language environment, use the .profile file to configure it under Linux and UNIX environments. To view the active code page settings under Windows, please type: chcp. A message similar to the following will appear: Active code page: 437. To change the To change the active code page to 850 (multilingual), type: chcp 850. If the specified code page is invalid, the following error message will be displayed: Invalid code page.

2. Database character set

Use specific commands to 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).

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 different under different versions of JRE. You can use %JAVAHOME%/bin/java The -version command checks 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.
