Variable and Data Type

Data Type (Python VS Java)

 Data type used in Python:

int – Used for whole numbers (e.g. 1, 10, 100)

float – Used for decimal numbers (e.g 1.4, 2.5, 3.0)

str – Used for any textual data (e.g. ‘John, “Peter”, “Male”)

You can use both single quote (‘john’) or double quote (“john”)

Data type used in Java:

int – Used for whole numbers as well

float, double – Used for decimal numbers

In this course, for simplicity, we will always use double to store decimal numbers.

String – Used for text data. Take note that only double quotation is allowed (“john”)

char- Is also know as single character. Take note that only single quotation is allowed ('a')
