Run the following java code of an Observer Pattern design in Object Oriented Design programming; in Netbeans. Provide screenshots as proof that it runs correctly. Draw a UML class diagram to model the program Java Code: //include the required packageimport java.io.*;import java.util.*;//create a main classpublic class experiment{ //definition of the main function public static void main(String args[]) { //create the object of the Scanner class Scanner in=new Scanner(System.in); //declare the required variables and arrays int time[]=new int[10]; float weight[]=new float[10]; String get; char ch; int i=0; //start of do while loop do { //try block try { System.out.print("\nEnter the time in seconds:"); time[i]=in.nextInt(); System.out.print("\nEnter the weight in kilograms:"); weight[i]=in.nextFloat(); i++; } //catch block catch(Exception e) { System.out.print("\nInvalid type"); } //print statements System.out.print("\n-----------------"); System.out.print("\n|Time\t|Weight\t|"); System.out.print("\n-----------------"); //for loop to print the time as well as the corresponding weight for(int x=0;x<i;x++) { System.out.print("\n|"+time[x]+"\t|"+weight[x]+"\t|"); System.out.print("\n-----------------"); } //to resist 10 entries in the table only if(i==10) { for(int x=0;x<9;x++) { time[x]=time[x+1]; weight[x]=weight[x+1]; } i--; } System.out.print("\nDo you want to continue?(y/n) "); get=in.next(); ch=get.charAt(0); }while(ch=='y' || ch=='Y'); //do while loop ends here } }
