Answer 1

Well as you mentioned there are two lines- First line takes number of integers and second takes that many number

INPUT: 5 2 456 43 21 12

So to address this and covert it into array -

String[] strs = inputData.trim().split("\\s+");  //String with all inputs 5 2 456 43 21 12

int n= Integer.parseInt(strs[0]);    //As you said first string contains the length

int a[] = new int[n];               //Initializing array of that length

for (int i = 0; i < n; i++)         
{

a[i] = Integer.parseInt(strs[i+1]);     // a[0] will be equal to a[1] and so on....

}
