✅ Basics (progress ongoing)
- Day 1: java programming setup ,flowchart ,pesudocode & basic hello world
- Day 2: basic java programing ,variable & data type
- Day 3: still stick to basic ,operators
- Day 4: still basic question(i know maybe its look to slow but turst me my comeback too stronger)
- Day 5: conditional statement problem ,finally little bit logical question we started
- Day 6: complete conditional staetement playlist
- Language: Java
- IDE: VS Code
- Version Control: Git & GitHub
- variable and data type :-type convertion ,type casting ,type promotion expression
- operator:- questions not solved fully
