JButtons is an object?

hi, im a beginner so pardon me if im wrong. Im quite sure that a button is an object. But from my understanding, objects can only be stored in Vectors, why is it that a normal array of buttons can be declared? Help anyone? Thanks

Yes JButton is an object but objects can not only be stored in Vectors.

Hi,

You can't typecast an int to a String. An int is a primitive data type and a String is an object consisting of an array of chars. You can however insert an int into a string, so one of the characters in your String will be the number you specified. However you will not be able to perform any numeric operations on it once it is stored in the String.

int i = 12;
String s = "" + i;
OR
String s = "12";
OR
String s = new String("12");
OR
String s = String.valueOf(i);

You can declare an array of anything, whether it's an array of int, double, String, JButtons, Dates, etc.

There's also an integer wrapper class (aptly named Integer) that you can also use to get a string object representing the int:

String s = Integer.toString(123);

// or;
Integer i = new Integer(321);
String r = i.toString();
