In the recent past, I visited a couple of companies for the interviews for automation engineer posts and there I was asked to write small programs which I have learnt in graduation days…
1. Print below pattern: This is one of the best programs to learn loop (you can try any among all provided java loops but here I am going to use for loop)
2. Print below pattern: This program is again going to use the same logic but in place of digits, * would be used
3. Program to read from file line by line: bufferedReader class provides readLine method to be used to read the file line by line.
public static void readFile() throws FileNotFoundException { FileReader fr = new FileReader(“C:’Users’…’Desktop’unused.txt”); BufferedReader br = new BufferedReader(fr); StringBuffer str = new StringBuffer(); try { while (br.readLine()!= null){ str.append(br.readLine()); } } catch (IOException e) { e.printStackTrace(); } System.out.println(str); }
public static void reverse() { String str = “I use selenium webdriver. selenium is a tool for web applications.”; int i = str.length(); StringBuffer strb = new StringBuffer(); for( int j=i-1; j>=0; j–){ strb = strb.append(str.charAt(j)); } System.out.println(strb); }

public static void replace() { String str = “I use selenium webdriver. selenium is a tool for web applications automation.”; String toBeReplaced = “selenium”; String toReplacedWith = “Firefox”; String[] astr = str.split(toBeReplaced); StringBuffer strb = new StringBuffer(); for ( int i = 0; i <= astr.length – 1; i++ ) { strb = strb.append( astr[i] ); if (i != astr.length – 1) { strb = strb.append(toReplacedWith); } } System.out.println(strb);
There could have been more ways to create the above programs. I would like to invite you all to find out those.
Along with this, I would suggest you, take this quiz to check your selenium interview preparation
#1 : Java Programming Interview Questions For Automation Testers With Answers
First, we convert the given ‘inputstring’ to char array and call it as ‘inputStringArray’. We define one more char array called ‘resultArray’ with the same size as ‘inputStringArray’. In the first for loop, for every space in the ‘inputStringArray’, we insert space in the ‘resultArray’ at the corresponding positions. In the second for loop, we copy non-space characters of ‘inputStringArray’ starting from first to last into the ‘resultArray’ at ‘j’ position where ‘j’ will have value from length of resultArray to 0. Before copying, we check whether the ‘resultArray’ already contains a space at index ‘j’ or not. If it contains, we copy the character in the next position. See the below for more clarity.
In this section, we are giving few java interview programs faced by some of my friends. If you come across any questions, post it to me. I can provide solutions. You can email me at [email protected]
Factorial of any number is the product of an integer and all the integers below it for example factorial of 4 is 4! = 4 * 3 * 2 * 1 = 24. In below code, I will show you how to design Java program to find factorial, using for loop you can perform this task.

Explain Java Main Method public static void main (String[] args)
When you start learning Java, the first method you encounter is public static void main(String [] args). The starting point of any Java Program is the main() method. It is one of the important methods of Java. Technically, the main method is the starting point where the Java program starts its execution. JVM always look for this method signature to start running an application. Check this to know detailed explanation.
