not able to understand this question,can any one clarify it

Scanner sc=new Scanner(System.in); int jum=sc.nextInt(); int jumtot=0; int count=0; int[] arrJum=new int[jum]; String test=""; for (int i = 0; i < jum; i++) { int val=sc.nextInt(); arrJum[i]=val;

    }


    for (int i = 0; i < arrJum.length; i++) {
        for (int j = i; j < arrJum.length; j++) {
            for (int j2 = i; j2 <= j; j2++) {
                jumtot+=arrJum[j2];

                test=test+String.valueOf(arrJum[j2]);
            }
            if(jumtot<0) count++;
            test="";
            jumtot=0;

        }
    }

    System.out.println(count);
