please do 2 and 3 ASAP

2. In the new class' code, replace the String colName property with an int lineWidth property. Change the constructor and the toString method to reflect this. 3. In the simulation, modify the createNewOp method so that there are three more switch cases for lineWidths of 1, 2,5. Make sure to change the number in the first statement of the method so that these new ops have a chance to be created. 4. Run the simulation and make sure that you are seeing shape drawing, color changes and line width changes. When you are finished, submit LineWidthOp.java to Canvas. 000 * 1 /* 2 * To change this license header, choose License Headers in Project Properties. 3 * To change this template file, choose Tools | Templates 4 * and open the template in the editor. 5 */ 6 package operationundo; 7 8 O /** 9 10 * @author clatulip 11 */ 12 public class LineWidthOp extends DrawingOp { private String colName; 14 15 public LineWidthop(String name, String colName) { 16 super(name); 17 this.colName = colName; 18 } 19 20 @Override public String toString() { 22 return super.toString() + " StateOp{" + "colName=" + colName + '}'; 23 } 24 25 } 26 1 2 * To change this license header, choose License Headers in Project Properties. 3 * To change this template file, choose Tools | Templates 4 * and open the template in the editor. 5 */ 6 package operationundo; 7 8 import java.util.
