In simple words, data type means which type of value a variable has. Basically, there are 8 data types.

  1. Boolean
  2. Char
  3. Byte
  4. Short
  5. Int
  6. Long
  7. Float 
  8. Double

  • The boolean data type is used to store true or false. 
  • A byte is a primitive data type and its value ranges from -128 to +127.
  • char is a primitive data type and it can hold a single character.
  • The short data type is a 16-bit signed two’s complement integer. The minimum value is -32768 and the maximum value is  32767.
  • The int data type is a 32-bit signed two’s complement integer. The minimum value is -2^31 and the maximum value is 2^31-1.
  • The float data type is a single-precision 32-bit IEEE 754 floating point. The float is used for decimal value.
  •  The long data type is a 64-bit two’s complement integer. The minimum value is -2^63 and the maximum value is 2^63-1.
  • The double data type is a double-precision 64-bit IEEE 754 floating point. The value is unlimited for double.
