Re: Reflect.getIndex() throws ArrayIndexOutOfBoundsException

It seems that the java file was withdrawn. It's contents are:


package testesBeanShell;

import bsh.EvalError;

public class Main {

    private final bsh.Interpreter beanShell = new bsh.Interpreter();;

    public static void main (String[] args){
        Main main = new Main();
        main.eval();
    }

    public void eval(){

        String expression =
"i=0;j=0;temp=0;time=System.currentTimeMillis();for(i=0;i<array.length;i++){if((System.currentTimeMillis()-time)>1000)return
null;for(j=0;j<array.length;j++){if((System.currentTimeMillis()-time)>1000)return
null;if(j<array.length&&i<array.length){temp=array[i];array[i]=array[j];array[j]=temp;}}if(j<array.length&&i<array.length){temp=array[i];array[i]=array[j];array[j]=temp;}}if(array[j]<array[j]){if(array[i]<array[j]){if(j<array.length&&i<array.length){temp=array[i];array[i]=array[j];array[j]=temp;}}}return
array;";
        String[] argNames = new String[] {"array"};
        Object[] argValues = new int[][] {{2, 9, 5, 7, 3}};

        Object result = null;
        if (expression != null) {
            try {
                // Declare all the variables.
                for (int i = 0; i < argNames.length; i++) {
                    beanShell.set(argNames[i], argValues[i]);
                }

                result = beanShell.eval(expression);

            } catch (final EvalError e) {
                e.printStackTrace();
            }
        }
        System.out.println((String)result);
    }
}



Thanks!
Best regards,
David
