}
Hi,
why is the class declaration above faulty?
The way I read it is that "int[]anArray = new int[100];" creates an integer array called anArray
then for the loop statement the array exists so why does the loop not work?
i get "an illegal start of type errror...."
for
for (int i = 0; i < anArray.length; i++)
anArray[i] = -1;
very dazed and confused
you should create the method for your stuff .
Do you mean a main method?
I will be calling this class from another test application which will have a main method. I do not need a main method in this class?
any method. you're trying to place code that needs to be within a method or constructor or static block outside of all of these things, and this is not kosher.
this is a class (below)i created before which compiles ok. I was using this as a template for the class that doesn't work, I dont really see the diference in construction between the two.
package labworkbook1;
public class ArrayStack {
int[] anArray= new int [5];
int top = 4;
int size = 5;
public int[] getArray(){
return anArray;
}
// method to check if the stack is full
public boolean isFull(){
return top==size-1;
}
//method to check if stack is empty
public boolean isEmpty (){
return top==-1;
}
// method to add (push) to the stack
public void push(int x)
{
if (isFull()) {System.out.println ("Stack is full");}
else
{
}
}
}
What Serjant means is that your class needs a method (like he said... any method). When you make a call to a class, you have to call a method in the class... you don't call the class itself. You can two one of two things:
- wrap a main method around your code and be able to execute the class' code directly or
- wrap other method around it and call that method from another class.
Luck,
