java

**Question 6:** What is the output of the following code? (Assume each class is defined in a separate java file). ```java public class MyFrame { private double length; private double width; public double x; public double y; public MyFrame(double len, double width, double x, double y) { this.length = len; this.width = width; this.x = x; this.y = y; } public void MyFrameMinimize(double per) { length -= length * per; } public double getLength() { return length; } } public class MyFrameTest { public static void main(String[] args) { MyFrame fr = new MyFrame(10, 12, 3, 8); fr.MyFrameMinimize(0.03); System.out.println(fr.getLength()); } } ``` **Choices:** - A. 0.0 - B. 9.7 - C. 10 - D. 9.9 --- **Explanation:** To determine the output, let's break down the code step by step: 1. **Class MyFrame:** - Contains private variables `length` and `width`. - Contains public variables `x` and `y`. - Constructor initializes these variables. - Method `MyFrameMinimize(double per)` reduces the `length` by a percentage `per`. - Method `getLength()` returns the current `length`. 2. **Class MyFrameTest:** - The `main` method creates an instance of `MyFrame` with initial variables (10, 12, 3, 8). - Calls `MyFrameMinimize` with 0.03 (3%). - Prints the new length using `getLength()`. Calculation: - Initial `length` = 10 - After `MyFrameMinimize(0.03)`: - Length reduced by 3%: `length -= length * 0.03` - `length = 10 - 10 * 0.03 = 10 - 0.3 = 9.7` Therefore, the output of `System.out.println(fr.getLength());` will be: **Answer:** - B. 9.7
