Why not declare it here? It does not need to be a field, moreover you don't
need it even as a local variable.

Setting L&F should rather be done on EDT as well, so I propose creating a
`runTest` method which will encapsulate the logic of the test:
public static void main(String[] args) throws Exception {
SwingUtilities.invokeAndWait(TableHeaderRendererTest::runTest);
System.out.println("Test Passed");
}
private static void runTest() {
UIManager.LookAndFeelInfo[] lookAndFeel =
UIManager.getInstalledLookAndFeels();
for (UIManager.LookAndFeelInfo look : lookAndFeel) {
System.out.println(look.getName() + " LookAndFeel Set");
setLookAndFeel(look.getClassName());
// initialize should not throw NullPointerException
initialize();
}
}
test/jdk/javax/swing/JTableHeader/TableHeaderRendererTest.java line 114:

> 114: private static void setLookAndFeel(String laf) {
Please add a blank line before the new method declaration.
