Java – How to enable anti aliasing in arbitrary Java apps

antialiasingjava

Many Java Apps don't use anti-aliased fonts by default, despite the capability of Swing to provide them. How can you coerce an arbitrary java application to use AA fonts? (both for applications I'm running, and applications I'm developing)

Best Answer

If you have access to the source, you can do this in the main method:

  // enable anti-aliased text:
  System.setProperty("awt.useSystemAAFontSettings","on");

or, (and if you do not have access to the source, or if this is easier) you can simply pass the system properties above into the jvm by adding these options to the command line:

-Dawt.useSystemAAFontSettings=on

Java – How to assert that a certain exception is thrown in JUnit 4 tests

It depends on the JUnit version and what assert libraries you use.

For JUnit5 and 4.13 see answer https://stackoverflow.com/a/2935935/2986984
If you use assertJ or google-truth, see answer https://stackoverflow.com/a/41019785/2986984

The original answer for JUnit <= 4.12 was:

@Test(expected = IndexOutOfBoundsException.class)
public void testIndexOutOfBoundsException() {

    ArrayList emptyList = new ArrayList();
    Object o = emptyList.get(0);

}

Though answer https://stackoverflow.com/a/31826781/2986984 has more options for JUnit <= 4.12.
