If you are a Java developer hunting for a new role, you have likely encountered the phrase "TestDome Java questions and answers" in your interview preparation. TestDome is a popular pre-employment screening platform used by companies like eBay, Autodesk, and McGraw-Hill to filter candidates efficiently. Their Java tests are notoriously tricky—not because they ask for obscure APIs, but because they focus on clean code, edge cases, performance, and object-oriented design.

In this article, we will break down the most common types of TestDome Java questions, provide correct answers with detailed explanations, and teach you the underlying principles to solve any variation they throw at you. If you are a Java developer navigating the

public class MergeArrays 
    public static int[] merge(int[] a, int[] b) 
        int[] result = new int[a.length + b.length];
        int i = 0, j = 0, k = 0;
    while (i < a.length && j < b.length) 
        if (a[i] < b[j]) 
            result[k++] = a[i++];
         else 
            result[k++] = b[j++];
while (i < a.length) 
        result[k++] = a[i++];
while (j < b.length) 
        result[k++] = b[j++];
return result;

Explanation: Standard two-pointer merge algorithm. Time complexity O(n+m), space O(n+m).

Task:
Implement a cache that stores key-value pairs with a time-to-live (TTL). After TTL milliseconds, the entry expires and should not be returned.

Write a method that reads only the first line of a file efficiently. Return empty string if file is empty or not found. The best resource is TestDome’s official practice tests

Alex’s thoughts:

His final safe version:

import java.io.*;
public class FirstLineReader 
public static String getFirstLine(String filePath) 
try (BufferedReader br = new BufferedReader(new FileReader(filePath))) 
return br.readLine();
 catch (IOException e) 
return "";

✅ Efficient, resource-safe (try-with-resources), returns empty string on error/empty file.

TestDome is widely used by employers to assess real-world Java skills. Unlike theoretical multiple-choice tests, TestDome focuses on writing correct, efficient, and maintainable code.
