How to use arrays with Math.random

[LennyKosmos]

Introduction: hi, im lenny from sweden and i've been studying java for almost 2 weeks! i'm wondering how i can assign values to an array, 0 = heads and 1=tails and use math.random to randomize the arrays to make it a 50-50% chance.



public class Krona {

private String heads, tails;
private String throw[];



public void throw(){

throw= new String[1];

throw[0]=heads;
throw[1]=tails;


int throwOne=(int)(throw.length*Math.random());
System.out.println(throwOne);
}


public class blabla {

public static void main (String [] args){

Throw Random = new Throw();
Random.throw();
}
}
}

ERROR:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 2
at Krona.kasta(Krona.java:14)
at mainkrona.main(mainkrona.java:7)


i dont understand this error :/

edit: turned out to be weird when i was about to translate my methods and variables from swedish to english but i hope u can understand it either way :S

[JosAH]

		throw= new String[1];
		
		throw[0]=heads;
		throw[1]=tails;

You want two elements in your array, element #0 and element #1 so the array in the first line should be new String[2], hence the exception that was thrown.

kind regards,
