Need help please

[likeafire]

I am testing a queue and im trying to insert a number onto the queue but i keep getting an error message saying - <identifier> expected. Anyone know how i can fix this so that i can output the number i want to add onto my queue. Any help will be much appreciated. Here is the code:

public class NewArray
{
ArrayPriorityQueue myarray = new ArrayPriorityQueue(5);

public void myprogobj();

System.out.println(myarray.enqueue(4)); (<identifier> expected)
}

public void myprogobj();

What is that line doing there?

kind regards,

Remove that line and take the next line (written in bold in your OP) to the body of a method; what you wrote isn't syntactically correct Java.

Ok this is what i have now:

public class NewArray
{
public void myprogobj()
{

ArrayPriorityQueue myarray = new ArrayPriorityQueue(5);

myarray.enQueue(4);
myarray.enQueue(3);

}
public static void main (String args[]){

System.out.println(myarray);
}
}



But the problem is i cant get it to output anything and an error is produced saying that it cannot find symbol - variable myarray where i have put System.out.prinln(myarray);

Its a scope problem. There is no variable myarray that is in scope for the main() method.
myarray is a local variable in the myprogobj method.
You need to move its definition outside of any methods so all methods can see it.

Your next problem will be trying to access a non-static variable from a static context.
