exception in thread main java.lang.arrayindexoutofboundsexception

[dwill19686]

Hi,

I am coding this program out of a book on creating a Two Dimensional array and keep running into this error (exception in thread main java.lang.arrayindexoutofboundsexception).

Could someone help me on how to correct this? Here is my code.

public class TwoDimensionArray {


public static void main(String[] args) {
float myarray[][] = {
{-56.7f},
{500.1f, 70.70f},
{100.9f, 0.5f, 20.20f}
};

System.out.println("myarray.length =" + myarray.length);

System.out.println(myarray[0][0]);
System.out.println(myarray[0][1]);
System.out.println(myarray[1][0]);
System.out.println(myarray[1][1]);
System.out.println(myarray[2][0]);
System.out.println(myarray[2][1]);

}

}

Look closely at your array assignment...what would you expect each value to be? (In particular, myarray[0][1])

The first row of your two dimensional array has just one element (stored at position (0,0)) so an attempt to read an element at position (0,1) causes an AIOOBE.

kind regards,

Ok. I know you both have been told this before, but i'm new and already you guys are awesome in my book. The book that I have is incorrect in the position it is setting and is what is causing the error. I'm a member for life. Thanks for your help and quick response.
