    Default I am new

    Hi guys! I'm very new to Java and doing basic java coding. I was wondering if any of you could help me whats wrong with my code. I'm just trying to do an if statement in which IF a the value of my equation is greater than or equal to 18 its good. But the ELSE function isnt working for me. I'm trying to see what mistake I'm making. Thank you.

    import java.util.Scanner;

    class apples{
    public static void main(String args[]){
    Scanner Alex = new Scanner(System.in);
    int fnum, snum, answer;
    System.out.println("Enter your age:");
    fnum = Alex.nextInt();
    System.out.println("Enter age of your girl:");
    snum = Alex.nextInt();
    answer = fnum / 2 + 7;
    if (answer >= 18);{
    System.out.println("Shes good for you");

    }else
    {
    System.out.println("She's not good for you");
    }
    }

    }

    1. When you get errors, post the exact error text or trace (no paraphrasing) and indicate whether it was a compile time or run time error. Don't expect forum members to read your mind.

    2. Read about the syntax of the if and if-else statements here:
    The if-then and if-then-else Statements (The Java™ Tutorials > Learning the Java Language > Language Basics)

    Then check your semicolons.

    import java.util.Scanner;
     
    class apples{
    	public static void main(String args[]){
    		Scanner Alex = new Scanner(System.in);
    		int fnum, snum, answer;
    		System.out.println("Enter your age:");
    		fnum = Alex.nextInt();
    		System.out.println("Enter age of your girl:");
    		snum = Alex.nextInt();
    		answer = fnum / 2 + 7;
           // what if frum % 2 !=0?
    // I mean, what if frum is not divisible by 2?
    // 7 /2 + 7 = 3 + 7 = 10
     
     
     
    // also, lose the ; after your if statement.  That is certainly causing an error.  
    		if (answer >= 18);{
    			System.out.println("Shes good for you");
     
    		}else
    		{
    			System.out.println("She's not good for you");
    		}
    	}
     
    }

    Get rid of that ; after the if. That's causing an error.
