Answer 2

Explanation:

public int sumOfLargest4(int [ ]a)

{// Sort the Array in Descending order. Exchange Sort is used here

int i, j, temp, n=a.length;

for(i=0; i<n-1; i++)

{for(j=i+1; j<n; j++)

{if(a[i] < a[j])

{temp=a[i];

a[i]=a[j];

a[j]=temp;

}

}

}

// Now return sum of first 4 in the Array

int sum=0;

for(i=0; i<4; i++)

{ sum+=a[i];

}

return sum;

}// End function
