first part
double[] arr=new double[50];
for(int i=0;i<25;i++)
arr[i]=i*i;
second part
for(int i=25;i<arr.length;i++)
arr[i]=3*i;
third part
for(int i=0;i<arr.length;i++)
{
if((i%10==0)&&i!=0)
System.out.println(arr[i]+" ");
else
System.out.print(arr[i]+" ");
}
I’m not sure if i understood you but the first part is the squared index, the second is the double index, the third is printing the array, notice that after every 10 printings it goes to a new line.
