Explanation:
The Integer is a wrapper class for int data type in the java programming language, The integer provides more flexibility in storing the data and manipulating the data .
The syntax of using Integer type is given below
Integer variable_name = new Integer("value");
For example
Integer a1 = new Integer("12") ;
Object is the class in java programming language which is present in java.lang package. Object also describe the return type of the java constructor.
>>> range (0,11,2)
