A few months ago, I kept making the same mistake.

I'd watch hours of Java and DSA tutorials, feel productive for a day, then disappear for a week.

Nothing was sticking.

So I made one small rule:

That's it.

Some days I spend only 20–30 minutes.
Some days I solve a hard LeetCode problem.
Other days I just review Java Collections or read documentation.

I stopped comparing myself to people who solve 500+ problems.

Now I compare myself to who I was yesterday.

What I've learned so far

• Consistency beats intensity.
• Understanding one concept deeply is better than solving ten problems without learning.
• Building projects teaches things tutorials never will.
• Asking questions is not a weakness.

I'm still a Computer Science student, and I still have a lot to learn.

But I'm enjoying the journey much more now.

What's one programming habit that genuinely improved your skills?

I'd love to learn from your experience.

I started taking my learning journey seriously this week.

Instead of trying to learn everything at once, I'm focusing on just a few things every day:

✅ Solve one DSA problem
✅ Learn one Java concept
✅ Read about one real-world development topic
✅ Share what I learned

I'm not an expert yet, but I've realized consistency teaches more than motivation.

If you're also learning programming, what's one habit that made the biggest difference for you?

I'd genuinely love to learn from your experience.

Hi everyone!

This is Day 2 of my Java & DSA journey.

Today I practiced one of the most popular interview questions: Two Sum.

Problem

Given an array of integers and a target value, return the indices of the two numbers whose sum equals the target.

My Java Solution

import java.util.HashMap;

class Solution {
    public int[] twoSum(int[] nums, int target) {
        HashMap<Integer, Integer> map = new HashMap<>();

        for (int i = 0; i < nums.length; i++) {
            int complement = target - nums[i];

            if (map.containsKey(complement)) {
                return new int[]{map.get(complement), i};
            }

            map.put(nums[i], i);
        }

        return new int[]{};
    }
}

What I learned today

• How HashMap helps reduce time complexity.
• Difference between brute force O(n²) and optimized O(n).
• Why storing previously seen values is useful.

I'm trying to improve my Java and DSA skills every day. If you have any tips for writing cleaner Java code or preparing for coding interviews, I'd love to hear them.

Thanks for reading!

why can i import item.hoeItem;
but not item.*;

AI is bullying me with my questions pls help

also if i Alt+Enter on an Import class, all of the sudden the import is not were every import is
its in the line

For full (not hybrid) remote working setup. Is there enough java jobs for this or are Go jobs more inclined to this working setup???

Hi everyone!

I'm a Computer Science student from India and I'm currently improving my Java, DSA, SQL, and Web Development skills.

My goal is to solve coding problems consistently and become a software engineer.

I'll be sharing:

• Java tips
• DSA solutions
• LeetCode explanations
• Interview preparation notes
• Small coding projects

If you have any advice for someone starting this journey, I'd love to hear it.

Thanks!

Paypal clone using java spring boot and kafka need help

Actually I was following @Mrunmai Dahare mam lecture in the vedio episode 3 : 16.21 timestamp I don't get what to change please help

So I've been recently getting into java and I've been teaching myself alot and i genuinely enjoy coding little projects but ny progress has been slowing down because i only know the basics stuff you need to make the most beginner games like tic tac toe and and rock paper scissors, so are there any tutorials or courses i should be taking?

Hi, I've studied java , but sometimes I have questions about why a virtual stream is needed , except for downloading skins and communication , nothing comes to mind .

Hey everyone,

I'm currently working on sharpening my Object-Oriented Programming (OOP) and software design patterns, and I just finished building a custom Tetris game engine completely from scratch using Java Swing.

Actually, I haven't finished it yet and there are lots of things I am planning to implement on this one. But attached is the photo of my program running on the background.

I would love to get some feedback or a code review from more experienced developers on my architecture, package structure, or any potential logical improvements I could make!

Thanks in advance for any insights!

I have been building a software program designed for retail traders. It is a Multi-System Trading Analytics +Risk Simulation Engine. I named it Trader-OS. Well one of the features it has is the Trade Importer that will eventually use API to access the csv files on different brokers platforms. My issue is I cant get it to completely decipher the data it refuses to add stop loss and take profits. When they are in the files. I started out manually entering every trade I made. Bit wanted it to be something that wouldn't confuse the customer. And this thing has been kicking my 🫏. It is mostly written in Javascript and CSS. I use node.js and Electron. Any who. If anyone has any feedback or experience with what im building message me and help a poor man out. Lol
