Hi!
try with this solution :

Code: Select all

package domain; //add packge domain 
// and right click over project select edit project properties and set main class option to : domain.HelloWorld
public class HelloWorld {

    public static void main(String[] args) {
        
        // class should be lowercase
        class Number {
            
            
            int number;
            public boolean isPositive() {
                
                if (number>0) {
                    
                    return true;
                }else {
                    
                    return false;
                }
         
            }
        } // close Number class   
            Number myNumber = new Number();
            
            myNumber.number = 7;
            
            if (myNumber.isPositive()) {
                
                System.out.println(myNumber.number +"is positive");
            }else {
                
                System.out.println(myNumber.number + "is not positive");
            }
    }

}
