What is the usage of the absolute value function in Java?

In Java, the function to find the absolute value is Math.abs(). It is used by passing a number as a parameter to the function, and then returning the absolute value of that number.

For example:

Declare a variable “num” with a value of -5. Calculate the absolute value of “num” using the Math.abs() method and store it in a variable “absNum”. Print the value of “absNum”, which is 5.

In the code above, we are using the Math.abs() function to calculate the absolute value of num and storing the result in the absNum variable, and then printing the result.
