  - ```MIN_VALUE``` & ```MAX_VALUE``` 

  - Overflow and underflow 

  - Underscore integer (JDK 7+) 

  - int = 2 x short = 4 x byte (bits)  

  

  📌 Tips

   


   
In precise calculation, use BigDecimal instead of floating point number (float, double)

     
Use -L, -f, -d suffix for long, float, double

      
Prefer double than float (faster, more precise)
