I write a program like this:

double degrees = 45.0;
double radians = Math.toRadians(degrees);
System.out.println(Math.tan(radians));

When I run this code I get the result is 0.9999999999999 Is there a way to calculate the correct tan function in java? Can you help me. Thank you!

Using doubles will always create rounding issues. If you don't care too much about precision you can simply round the result to n decimals.
