- 6. Byte • For Storingwhole Numbers • It stores a value between -128 to 127 • Size = 1 byte • Value = 0
- 7. Short • For StoringWhole Numbers • It stores value between -32,768 to 32767 • Size = 2 byte • Value = 0
- 8. Int • For StoringWhole Numbers • It stores value between -2,147,483,648 to 2,147,483,647 • Size = 4 byte • Value = 0
- 9. Long • For StoringWhole Numbers • It stores value between 9,223,372,036,854,775,808 to 9,223,372,036,854,775,807. • Size = 8 byte • Value = 0
- 10. Double • It isused for Fractional Numbers • It stores upto 15 decimal digits • Size = 8 byte • Value = 0
- 11. Float • It isused for Fractional Numbers • It stores upto 7 decimal digits • Size = 4 byte • Value = 0
- 12. Boolean • It isused to tell either true or false
- 13. Char • It isused in character • Size = 2 bytes
- 14. For Example: • inti = 10; • byte b = 5; • short s = 10; • long = 123l; • float = 23.9f; • double = 34.98d; or 34.98 • boolean = true; or false; • char = ‘A’;
- 15. Array Array is classifiedinto two types: 1. Single-Dimension Array 2. Multi-Dimension Array
