There are 9 types of data types. These include boolean, string, integer, double, decimal, character, byte, float and long.
- Boolean is a binary value, being either true or false.
true
- String is used for storing characters in word form.
"hello world"
- Integer is used to store whole numbers (32 bit values).
457568368
- Double is used to store numbers where there are numbers before and after the decimal point.
3.3
- decimal is used for numbers only after the decimal point.
.3
- Character is used to store single letters.
'A'
- Byte is used to store a byte( eight 1's or 0's).
00101101
- Float is used to store a set number of digits after a decimal place.
3.0000000000
- Long integer is also used to store whole numbers (However these are 64 bit values).
7846354759340276482
- Constants are used to create a variable of a specified data type that can never be changed after declaration, all global variables should be declared constant.
const int 32
