Change an myArray[] into a String

Question

Hi all,
i was just wondering if there is a way to change an int[] array called myArray[] into a String to be printed out in the command prompt? i have been using a for loop to run through each index of myArray[] and print it out, but i thought that there must be a way to convert the int[] array into a string and print all the elements out at once. i want to avoid the loop, is it possible?
Thanks
Jay

JayJay,
An Array in java is an object, not a primitive, and inherits the toString() method from Object, which prints the object reference. Do you have to use an array? If you use Vector, which implements a growable array, you can take advantage of the fact that Vector has a redefined toString() method which prints the elements of the Vector.
For example:
Vector myIntVector = new Vector();
myIntVector.add( 1 );
myIntVector.add( 2 );
myIntVector.add( 3 );
System.out.println( myIntVector );will print
[1, 2, 3]
