Checks if the two objects equal. If both are the same instance, they are equal. If both are null, they are equal. If o1 and o2 both are Comparable, we will use compareTo method to see if it equals 0. If considerArrayOrList is true and o1 and o2 are both array, we will compare each element in the array. At last, we will useo1.equals(o2)
to compare. If none of the above conditions match, we return false.- Parameters:

shouldUseSystemFont
public static boolean shouldUseSystemFont()
In JDK1.4, it uses a wrong font for Swing component in Windows L&F which is actually one big reason for people to think Swing application ugly. To address this issue, we changed the code to force to use Tahoma font for all the fonts in L&F instead of using the system font. However this is a downside to this. Tahoma cannot display Unicode characters such as Chinese, Japanese and Korean. So if the locale is CJK (SystemInfo.isCJKLocale()
, we shouldn't use Tahoma. If you are on JDK 1.5 and above, you shouldn't force to use Tahoma either because JDK fixed it in 1.5 and above. There are also a few system properties you can set to control if system font should be used. "swing.useSystemFontSettings" is the one for all Swing applications. "Application.useSystemFontSettings" is the one for a particular Swing application. This method considers all the cases above. If JDK is 1.5 and above, this method will return true. If you are on Chinese, Japanese or Korean locale, it will return true. If "swing.useSystemFontSettings" property us true, it will return true. If "Application.useSystemFontSettings" property is true, it will return true. Otherwise, it will return false.
