Thread: Beginner at Java: I need to figure out how to print a number which is odd and negative and fits in a formula.

how I can print an int

Can you use the System.out.println() method to print it?

That answers the question. Did you have any other questions?

Are you asking how to determine if a number is odd and negative?
A test for even or odd is to compare the results of theNumber % 2 : 1 is odd, 0 is even
A test for negative is if theNumber < 0

I am getting problems

Sure! Hold on...

package variables;
public class SimpleCalc {
		public static void main(String[] args){
			int n=11;
			if (n<0){
			if (n%2);                                           //Error Message occurs here: Mismatch - cannot convert to boolean
				System.out.println(n^2+(n/2));
				}
			if (n>=0) {                                         //The ones after this are fine
				System.out.println(n^3*(n-1));
				}
 
			if (n>=0) {
				System.out.println(n^-1*(3*n));
				}
	}
}

The expression in the if statement must use a boolean operator that returns a boolean result. % returns a numeric value.
See the tutorial for a list of operators that return a boolean result:
Equality, Relational, and Conditional Operators (The Java™ Tutorials > Learning the Java Language > Language Basics)
The if statement requires a boolean value, not a numeric value.

a == b is a boolean value
a + b is a numeric value
(a + b) > 3 is a boolean value
