数组中的数组比较

Question

为什么当我在java中比较两个数组时，结果总是出现false？

package let3;
public class compare {

    public static void main(String[] args) {
   /////array with array////
        int l[]={5};
        int y[]={5};
        ////compare by == ////
        if (l==y){
            System.out.println("true ==");
        }else{
            System.out.println("false ==");
        }
        ///////compare by equal////
        if (l.equals(y)){
            System.out.println("true equal ");

        }else{
            System.out.println("false equal ");
        }
    }
}
