What is Data Type Default value , Size and range ?

The default data type in Java is int. To store integral values, unless there is a concern about memory, int is generally used. Later in Java SE 8, the int data type in Java represents an unsigned 32-bit integer, which has the range of values [0,232 -1].12
Data ranges of a data type arises from the combinations of values which can be represented from the amount of memory assigned for a single unit of the single data type, and how those possible combinations are assigned to actual values that they represent.
The difference between the highest and lowest observations in a given data is called its range.
To calculate the range, you need to find the largest observed value of a variable (the maximum) and subtract the smallest observed value (the minimum). The range only takes into account these two values and ignore the data points between the two extremities of the distribution.
