Read the java program carefully, compile the program and understand the compilation errors. Don't change access specifier for variables. What needs to be done to correct the compilation errors? class Box { private double width; private double height; private double depth; // compute and return volume double volumel { return width * height * depth; } } public class Box Demo { public static void main(String args[]) { Box myBox1 = new Box(); Box myBox2 = new Box(); myBox1.width = 10; myBox1.height = 20; myBox1.depth = 30; myBox2.width = 40; myBox2.height = 40; myBox2.depth = 40; double vol; Il get volume of first box vol = myBoxl.volume(); System.out.println("Volume for myBoxl is " + vol); // get volume of second box vol = myBox2.volume(); System.out.println("Volume is " + vol); } }
