<Identifier> Expected:

Question

I'm getting an error on this line, about how my array is imported into my JUNIT.

package test123;
import java.io.File;
    import java.io.FileNotFoundException;
    import java.util.ArrayList;
    import java.util.Scanner;
    import javax.swing.JFileChooser;
    import java.util.*;

        public class mainJUNIT
           {
            main2.array.length();

            @Test
            public ArrayList<Integer> test (ArrayList<Integer> N)
            {   
            ...
            }

My error is flagging my main2.array.length(); I have absolutely no idea why.

`javac main2.java mainJUNIT.java
mainJUNIT.java:12: error: <identifier> expected
    main2.array.length();
                      ^`

Any advice? I'm stuck. I can't get rid of this at all. I'm sure it's something stupidly easy, but I can't figure it out. main2 is another java class (main2.java) that I'm trying to get the array from.

Answer 1

Your call to main2.array.length(); in your class is not in any method, therefore you cannot call the method.

Also, the length in array is a field not a method, therefore main2.array.length() should be main2.array.length (returns an int).

Your call to length should be assigned to a variable:

for example:

package test123; import java.io.File; import java.io.FileNotFoundException; import java.util.ArrayList; import java.util.Scanner; import javax.swing.JFileChooser; import java.util.*;

public class mainJUNIT
{
    int length = main2.array.length;

    @Test
    public ArrayList<Integer> test (ArrayList<Integer> N)
    {   
    ...
    }
}
