Code coverage and Node coverage

please help me to do these questions..

1.What is the the minimal set for 100% Node Coverage?

2.What's the coverage level of Edge coverage for the above given Test set?

`public static void bubbleSort(int[] numArray) {

int n = numArray.length;                           //NODE1
int temp = 0;                                      //NODE1

for (int i = 0; i < n; i++) {                      //NODE2
    for (int j = 1; j < (n - i); j++) {            //NODE3
        if (numArray[j - 1] > numArray[j]) {       //NODE4
            temp = numArray[j - 1];                //NODE5
            numArray[j - 1] = numArray[j];         //NODE5
            numArray[j] = temp;                    //NODE5
        }
    }
} 

Sysytem.ot.println("end"); //NODE6 }`
