Convert the JavaScript array to a Java int array
#How to add external classes to java textpad 8 how to#
The following example shows you how to convert a JavaScript array to a Java array using various Java.to() method arguments: Conversion is performed according to the ECMAScript conversion rules. You can also omit the array type argument to return an Object array. You must pass the JavaScript array variable to this method and the type of array to be returned, either as a string or a type object. Given a JavaScript array, you can convert it to a Java array using the Java.to() method. The syntax for accessing array elements and the length property in JavaScript is the same as in Java, as shown in the following example: To create a Java array object, you first have to get the Java array type object, and then instantiate it. from the imported packages by their simple names within the statement's body Pass the JavaImporter object to the "with" statement and access the classes Var Gui = new JavaImporter(java.awt, javax.swing) Create a JavaImporter object with specified packages and classes to import To avoid this, define a JavaImporter object and use the with statement to limit the scope of the imported Java packages and classes, as shown in the following example: Furthermore, importing any Java package or class can lead to conflicts with the global variable scope in JavaScript. The java.lang package is not imported by default, because its classes would conflict with Object, Boolean, Math, and other built-in JavaScript objects. You can access Java packages using the Packages global variable (for example, or ), but standard Java SE packages have shortcuts ( java for Packages.java, javax for Packages.javax, and org for ). The following example shows you how to use the importPackage() and importClass() functions: These functions are built into the compatibility script ( mozilla_compat.js). To access Java classes by their simple names, you can use the importPackage() and importClass() functions to import Java packages and classes. However, there is no equivalent of the static property for a Class object in Java, because compile-time class expressions are never expressed as objects. Syntactically and semantically, this distinction between compile-time class expressions and runtime class objects makes JavaScript similar to Java code. Print("Type is the same as the `static` property of the instance's getClass(): " + (a.getClass().static = ArrayList)) Print("Type's `class` property is the same as instance's getClass(): " + (a.getClass() = ArrayList.class)) Print("Type is not the same as instance's getClass(): " + (a.getClass() != ArrayList)) Print("Class doesn't act as target of instanceof: " + !(a instanceof a.getClass())) Print("Type acts as target of instanceof: " + (a instanceof ArrayList)) The following example shows this distinction: You can obtain one from the other using the class and static properties. In case of a nonstatic inner class, you must pass an instance of the outer class as the first argument to the constructor.Īlthough a type object in JavaScript is used similar to the Java class, it is distinct from the object, which is returned by the getClass() method. If you already have the outer class type object, then you can access the inner class as a property of the outer class as follows:
The following example shows how to return the type object of the Float inner class in 2D: To access a static inner class, use the dollar sign ($) in the argument passed to the Java.type() method. You can use the type object returned by the Java.type() function to access static fields and methods as follows: Var customSizeArrayList = new ArrayList(16) Var defaultSizeArrayList = new ArrayList The following example shows you how to instantiate new objects using the default constructor and by passing arguments to another constructor: Java type objects can be used to instantiate new Java objects. For example, you can can use it to instantiate new objects as follows:

The type object returned by the Java.type() function can be used in JavaScript code similar to how a class name is used in Java. The following example shows you how to get various type objects:

To access primitive and reference Java types from JavaScript, call the Java.type() function, which returns a type object that corresponds to the full name of the class passed in as a string.
