Create a GUI (Graphical User Interface) based calculator application that will provide for adding, subtracting, multiplying, or dividing two numbers provided by the user. The application will have two labeled text fields for user to enter two decimal numbers. It will have another labeled non-editable text field for displaying the result. It will have five buttons labeled: Add, Sub, Mult, Div, and Clear. The user will enter the two numbers in the first two text fields and press an operation button such as Add. The application will display the result of performing the required operation in the third field. If the user presses the Clear button, it will clear all the three text fields.

(java)3. the answer is  (c): x[2] = 12; if x is an array with three elements, the first element has index 0. the second index has index 1. the third and final element has index 2.4. the answer is (d) for (int y : x) { system.out.println (y) ; }this is an example of syntax  of a "for-each loop."for each element in the integer array x, use y to indicate the current element to do some code with it.the other choice, (c) for (int x : y) { system.out.println (y) ; }. in a for-each loop, the variable to the right of the colon is the array variable; the one to the left is the control variable.choices (a) and (b) have invalid syntax.5. the answer is (a)  int x = {1, 2, 3, 5, 10}; you need to indicate that it is an array using []. without using [], you are trying to assign an array to an integer. you need to use int[] to indicate integer array.so choice (a) has incorrect syntax.
