Java math function to convert positive int to negative and negative to positive?

In Java, you can convert a positive integer to its negative counterpart and vice versa by using the unary minus operator (-). Here's how you can do it:

  1. To convert a positive integer to its negative counterpart:

    int positiveNumber = 42; int negativeNumber = -positiveNumber;

    In this code, negativeNumber will contain -42, which is the negative counterpart of the original positive number.

  2. To convert a negative integer to its positive counterpart:

    int negativeNumber = -42; int positiveNumber = -negativeNumber;

    In this code, positiveNumber will contain 42, which is the positive counterpart of the original negative number.

The unary minus operator (-) negates the value of the integer, effectively changing its sign from positive to negative or vice versa.
