Double class: The Double class is another built-in class in Java that represents floating-point numbers with decimal places. It is similar to the Integer class but allows for more precise calculations involving fractions or real numbers.
Wrapper classes: In Java, wrapper classes are classes that wrap primitive data types (like int or double) and provide additional functionality. The Integer class is an example of a wrapper class because it wraps the int data type and provides extra methods and features.
Arithmetic operators: These are symbols used in programming languages (such as +, -, *, /) to perform mathematical operations. The Integer class utilizes these operators internally to perform arithmetic calculations on integer values.
