一个数组中最大子数组的和并且加上测试用例

数组代码：
public class Maxsum {
    public  int Max(int Array[],int size){
        int max=Array[0];
        int num;
        int sum=max;
        for(num=1;num<size;num++)
        {
            if(sum<0)
                sum=Array[num];
            else
                sum+=Array[num];
            if(sum>max)
                max=sum;
        }
        return max;
    }
    public static void main(String[] args){
        Maxsum sum=new Maxsum();
        Scanner in=new Scanner(System.in);
        int size=in.nextInt();
        int []Array=new int[size];
        int num;
        for(num=0;num<size;num++)
            Array[num]=in.nextInt();
        System.out.println(sum.Max(Array,size));
        in.close();
    }
}



测试用例代码：

public class MaxsumTest {

    Maxsum sum=new Maxsum();
    @Before
    public void setUp() throws Exception {

    }

    @After
    public void tearDown() throws Exception {

    }
    @Test
    public void testMax1() {
        int []Array=new int[]{1,-2,4,-1,-5};
        assertEquals(4, sum.Max(Array,5));
    }
    @Test
    public void testMax2() {
        int []Array=new int[]{1,-2,-4,1,5};
        assertEquals(6, sum.Max(Array,5));
    }
    @Test
    public void testMax3() {
        int []Array=new int[]{1,2,3,1,1};
        assertEquals(8, sum.Max(Array,5));
    }
    @Test
    public void testMax4() {
        int []Array=new int[]{-1,-2,-4,-1,-5};
        assertEquals(-1, sum.Max(Array,5));
    }
    @Test
    public void testMax5() {
        int []Array=new int[]{0,0,0,0,0};
        assertEquals(0, sum.Max(Array,5));
    }
}
