13. Identify the output of the following code snippet: -
package this_keyword;
public class UsageOfThis {
int i=1;
public void method1(UsageOfThis ref) {
System.out.println(ref.i);
System.out.println(i);
System.out.println(this.i);
}
public void method2(){
System.out.println(i);
UsageOfThis ref2 = new UsageOfThis();
this.i=3;
i=6;
System.out.println(this.i);
System.out.println(ref2.i);
method1(this);
}
public static void main (String[] args){
UsageOfThis ref1 = new UsageOfThis();
ref1.method2();
System.out.println(ref1.i);
}
}
14. Identify the Output of the following code snippet :-
package rough;
public class DIL{
{
int i=9;
}
int i=0;
{
int i =8;
}
public static void main (String[] args){
DIL ref = new DIL ();
System.out.println(ref.i);
}
}
15. Identify the Output of the following code snippet :-
package rough;
public class DIL{
{
i=9;
}
int i=0;
{
i =8;
}
public static void main (String[] args){
DIL ref = new DIL ();
System.out.println(ref.i);
}
}
16. If you are reviewing a code written to automate, how would you go about doing this activity?
17. If you are writing code in Java, please explain the UMl artifacts you will want to create, and why.
18. If there is a need to run your tests across environments (DEV,QA, etc.) explain in detail, the steps you will take to ensure that one ca run tests across environments with ease.
19. If you are using recursion to solve any problem, what are the guidelines you will follow?
20. Automate the following scenario :
a. Open a website www.xyz.com
b. Click on a button whose attribute “id” is dynamic in nature (e.g., id=”abc123”,”abc3531” and so on…where text “abc” is static)
c. On clicking above button a new browser window opens up.
d. Go to new browser window and select the 11th dropdown option fron drop down menu(id=drpdwn) where the DropDown is inside a fram (id=frameid1)
e. On selecting the above drop down option a confirmation message “Option Saved successfully” shows up(outside the frame) – Validate this message (Your Test Case will Pass/Fail on this validation and you are not allowed to use any conditional statements like if – else to validate)
f. Close the Parent Window.
21. What do you expect as output: -
SELECT id, YEAR(BillingDate) AS BillingYear FROM invoices WHERE BillingYear >=2010;
22. Tell the output: -
Class A {
public static void main(String args[]){
String str1 =”ABCD”;
String str2 = new String(“ABCD”);
if (str1.equals(str2)){
System.out.println (“Hello1”);
}
if (str1==str2){
System.out.println (“Hello2”);
}
if (str1.equalsIgnoreCase(str2)){
System.out.println (“Hello3”);
}
}
}
23. Write a short note on using XML,JSON – can you enumerate principal benefits of using any of these?
24. Use regular expression to change “dd-MON-YYYY” to “MON/YYYY/DD”.
25. Write a program to count the number of occurrences of an integer in an array.
Ex:- int[] arr= {2,4,6,2,8,9,4,4}
O/P :- 2 occurred 2 times; 4 occurred 3 times and so on.
Enjoy Interview.
