"Only constructors can invoke constructors" Code: class MyGroupBox { public void MyGroupBox(int x, int y, int intWidth, int intHeight) { this(x, y, intWidth, intHeight, ""); } public void MyGroupBox(int x, int y, int intWidth, int intHeight, String strCap...

A special require 'java' directive in your file will give you access to any bundled Java libraries (classes within your java class path). If you need to access Java libraries not contained with the Java class path we will show you how to do that in a later section....
The method name is the Java method name in UTF-8 form. Specify the method name for a constructor of a class by enclosing the wordinitwithin angle brackets (this appears as "<init>"). Note that the JNI uses method signatures to denote the type of Java methods. The signature(I)V, for...
