Thread: Help with three lines

oh sorry i did it after i posted it:

import java.util.Scanner;
public class GtoJ {
public static void main(String[] args) {
     int mm, dd,yy;
     int [] mod= {31,28,31,30,31,30,31,31,30,31,30,31};
Scanner Sel= new Scanner (System.in);
     System.out.println (" Input Year:");
     yy= Sel.nextInt( );
if (yy%400==0||(yy%100!=0&&%yy%4==0)) 
{mod [1]=29;}
    System.out.print("1 for GtoJ (),2 for J to G ()");
    int s= Sel.nextInt();
    if (s==1)
{
        int m = Sel.nextInt ();
        int d = Sel.nextInt ();
        System.out.println ("Input 2 digit number:");
            GtoJ (m,d,mod);
else {System.out.println ("Input 3 digit Julian:");
        int ddd= Sel.nextInt ();
        JtoG (ddd,mod);
        }
    }
}

For the errors i got this:For the line:

if (yy%400==0||(yy%100!=0&&%yy%4==0))
illegal start of expression

else {System.out.println ("Input 3 digit Julian:");

-else without 'if'

JtoG (ddd,mod); & GtoJ (m,d,mod);
-Cannot find symbol
symbol method: GtoJ (int, int,int [])
location class GtoJ
Surrounded with
...introduce


Those are the errors within the program and once i run it:

run:
Input Year:
1992
Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - illegal start of expression
at gtoj.GtoJ.main(GtoJ.java:13)
Java Result: 1
BUILD SUCCESSFUL (total time: 3 seconds)

oh, i dont know if this is better i added a screen shot

I fixed the error in the 'If' statement its only lines 22,23,25 that i dont understand im not sure what to put infront of the GtoJ and JtoG

oh i dont think it does that im netbeans, i have a mac

GG

I don't use Macs, so I cant help you there. As for your code, it's difficult to read because you have { and } placed very awkwardly. Keep in mind, with NetBeans, it will show you which braces open and close each other based on how you wrote it and if there are too many, however, it does not check whether there are logical errors resulting from misuse of braces. From one of your screenshots, on lines 22 and 25 have several errors. First, you're trying to pass variables into a class instead of into a method. Second, you're trying to pass an integer array as an integer. Third, the methods GtoJ and JtoG do not exist anywhere in the code you provided, which is why the compiler is giving you those errors for it.

Although it's not an error, on line 8, you never do anything with 2 of the 3 int variables. What is their purpose in your code? If they have none, delete them. Also, what are you trying to use the array for because you only have one of its elements replaced by 29?

Adjust the formatting and it's possible you'll find more errors. A chunk of your code needs to be re-written, so fix the other errors that are easier to handle first.
