Question

6. From the following flow-chart, write the java code. false a<100 print Done true print Bad a++ 7. Given an array int[] myarray = {2, 4, 6, 8, 9, 7, 5, 3, 1, 0} Create a trace table for variables involved in the following code int s = 10; for (int i = 3; i <7; i++) S = S + myarray[i]; What is the final value of s? 8. Given an ArrayList object mywords of the content Avengers Endgame is great and fun What is the output of code int k = mywords.size(); int i = 2; if (i < k)) System.out.println (mywords.get(i));

Answer 1

ans 6:

1 import java.util.*; 2 public class Main 3- { public static void main(String[] args) { Scanner sc=new Scanner(System.in); System.out.print("Enter value of a:"); int a=sc.nextInt(); while(a<100) /*here we take input of af a*/ /*we do untill a<100*/ system.out.println("Bad"); a++; /*if condition true than we print this*/ System.out.println("Done"); /*when it get false than we print this*/

output:

Enter value of a:95 Bad Bad Bad Bad Bad Done ... Program finished with exit code o Press ENTER to exit console.

code:

import java.util.*;
public class Main
{
   public static void main(String[] args) {
       Scanner sc=new Scanner(System.in);
       System.out.print("Enter value of a:");
       int a=sc.nextInt(); /*here we take input of af a*/
       while(a<100) /*we do untill a<100*/
       {
       System.out.println("Bad"); /*if condition true than we print this*/
       a++;
       }
       System.out.println("Done"); /*when it get false than we print this*/
      
   }
}

ans 7:

Trace table of program myarray[i] 1= 38 1=4 9 1=5 1=6 5 s=s+myarray[i] 10+8=18 18+9=27 27+7=34 34+5=39 ► In the above trace table For i=3,3<7 so condition getting true so s=s+myarray[i] , s=10+8=18 ► For i=4,4<7 so condition getting true so s=s+myarray[i] , s=18+9=27 ► For i=5,5<7 so condition getting true so s=s+myarray[i] , s=27+7=34 For i=6,6<7 so condition getting true so s=s+myarray[i] , s=34+5=39 > For i=7,7<7 so condition getting false So Final value of s=39

final value of s = 39

ans 8:

ovou ĐWN import java.util.*; 2 public class Main 3- { public static void main(String[] args) { ArrayList<String> mywords = new ArrayList<String>(100);/*here we make ArrayList object*/ mywords.add("Avenger Endgame is great and fun" ); /*store your content in mywords*/ /*store size of mywords into k*/ int k=mywords.size(); int i=2; if(i<k) /*check condition get true or false*/ 12 System.out.println(mywords.get(i)); T 13

output:

... Program finished with exit code 0 Press ENTER to exit console.

here we get blank output because only one data is in mywords.so,k=1 so 2<1 getting false......
