Data Types Data Types byte used to store the small digit numbers Range = -128 to 127 short used to small numbers Range = -32768 to 32767 int used to store integer values Depends upon processor char used to store any single character uses 2 bytess in java and 1 byte in C float used to store the decimal values upto 6 decimals Place 'f' after the last digit of the number double used to store the decimal values upto 8 - 10 decimals long used to large numbers Place 'L' after the last digit of the number NOTE:- If we the given range is exceed its range value then it comes from lower to upper range repeatedly Example : - byte a=128; byte b=130; System.out.println(a+" "+b); output :- -128 -126
