LZ help with the following: True/False In java it is possible to throw an exception, catch it, then re-throw that same exception if it is desired GUIs are windowing interfaces that handle user input and output. An interface can contain defined constants as well as method headings or instead of method headings. When a recursive call is encountered, computation is temporarily suspended; all of the information needed to continue the computation is saved and the recursive call is evaluated. Can you have a static method in a nonstatic inner class?

A binary operator is an operation that is performed on two operands. For example, addition is a binary operator that adds two operands (e.g., 2 + 4). In the provided UML diagram, all binary operators have two operands and an execute method that performs the appropriate operation on the operands. The AddOperation class should add the two operands. The SubtractOperation class should subtract the two operands. Here is an example of how a binary operator could be used: IBinaryOperator operator = new AddOperator(8, 12);System.out.println(operator.execute()); // should print 20operator.setLeftOperand(18);System.out.println(operation.execute()); // should print 30 crate a Main.java to test your code

Java programming - please see attched image for initial instruction before the following below. Write a subclass of VowelSeparator that adds three additional methods and a constructor. The class should be named VowelSeparatorAndCounter. Here are the methods to add: void setString(String s) This method should replace the string stored by the object with s. If the argument is null then the method should throw an IllegalArgumentException. (This is an unchecked exception) int getVowelCount() This method should return the number of vowels in the string.int getNonVowelCount() This method should return the number of characters in the string that are not vowels. Write a static method that accepts an array of VowelSeparatorAndCounter objects and returns the total number of vowels contained in all of them. It should have the following signature: public static int totalVowelCount(VowelSeparatorAndCounter[] a)
