public class dereks {
public static void main (String [] args){
    int array [] = {1,2,3,5,6,7};
    int sum =0;
    for(int counter=0; counter<=array.length; counter++){
        sum+=array[counter];
    }
    System.out.println(sum);
}
}

谁能告诉我这有什么不对？我无法理解为什么我收到错误消息"线程中的异常"主"java.lang.ArrayIndexOutOfBoundsException:5 at dereks.main(dereks.java:7)".
