• Exception handling. You can throw and catch exceptions using the throw and try...catch statements. See "Exception Handling Statements" on page 81.
• New operators in and instanceof. The in operator returns true if the specified property is in the specified object; see "in" on page 50. The instanceof operator returns true if the specified object is of the specified object type; see "instanceof" on page 50.
• Changes to LiveConnect. Several changes to LiveConnect improve the way Java and JavaScript code communicate:

• JavaClass objects are automatically converted to instances of java.lang.Class when you pass them as parameters to methods. See "JavaClass objects" on page 152.
• You can pass a one-character string to a Java method which requires an argument of type char. See "Arguments of Type char" on page 140.
• If your JavaScript code accesses a Java data member or method and fails, the Java exception is passed on to JavaScript for you to handle. See "Handling Java Exceptions in JavaScript" on page 141.
• Enhancements to the JSException class change the way you handle JavaScript exceptions in your Java code. See "Handling JavaScript Exceptions in Java" on page 144.
• Changes to the Function object. You should no longer specify a function name when using the arguments array; the arguments array is a variable and is no longer a property of Function objects. This change improves performance. See "Using the arguments Array" on page 87.
