Why is array not working in this code?

[redtribal23]

Why this doesn't work?

class Faculty extends Employee 
{
    private long[] officeHours;
    private String rank;

    public Faculty(long[] hours, String rank)
    {
        this.officeHours = hours;
        this.rank = rank;
    }

 public static void main(String[] args){


     //some code here

     Faculty f = new Faculty(newToken[], tokens[tokens.length-1]);

Maybe newToken is not an array of longs, but if it is, then certainly because tokens[tokens.length-1] isn't a String

[Traevel]

Because of something missing in the //some code here part. You can do long[] newToken or long newToken[]to get an uninitialized array. long[] newToken[] would give you a multidimensional array. For instance:

long[] newToken = new long[] {123,456,789};
long oldToken[] = new long[] {987,654,321};
long[] midlifeToken[] = new long[2][2];
        midlifeToken[0][0] = 123;
        midlifeToken[0][1] = 234;
        midlifeToken[1][0] = 345;
        midlifeToken[1][1] = 456;


String[] tokens = new String[] { "token1", "token2", "token3" };

// newToken contains 123, 456 and 789
Faculty f = new Faculty(newToken, tokens[tokens.length - 1]);

// oldToken contains 987, 654 and 321
        f = new Faculty(oldToken, tokens[tokens.length - 1]);

// midlifeToken contains 123 and 234
        f = new Faculty(midlifeToken[0], tokens[tokens.length - 1]);

I have the updated code.

is this code working ? if not, it would be easier if you mentioned the error message you get.

Tell the error msg. It will help to sort it out
