Data types in JAVA

Data types:

        In java every variable has a type and every expression should have a type, every type is strictly defined. All variable assignments must be checked by the compiler for type compatibility hence java is considered as strongly typed language

byte à Capacity : 1 byte  Range: -128 to +127

    It is best suitable for file transfers via networks 

short à capacity : 2 bytes Range: -215 to +215 -1

    it is best suitable for 16 bit processors.

int à capacity : 4 bytes  Range: -2³¹ to +2³¹ - 1

   In C language int capacity varies platform to plat form. Hence C  program results varies from platform to platform. Where as in JAVA int capacity is constant irrespective to platform.

long à capacity : 8 bytes Range: -2⁶³ to +2⁶³ -1

     if any integer value excessed  int value then we will go got long data type

float à Capacity : 4 bytes Range: -3.4e38 to +3.4e38 -1

   if we wants to consider to 7 decimal of accuracy we will go for float

double à Capacity : 8 bytes Range: -1.7e308 to +1.7e308 -1

   if we wants to consider to 15 decimal of accuracy we will go for double. Float and double types are best suitable for mediacl operators, satellite operations….

char à Capacity: 2 bytes. Range 0 to 65535 (no –ve values)

boolean à the capacity is virtual. No capacity and range

   In c language 1 represents true 0 represents false. But in JAVA we have literals true & false
