Answer:
Here is code in java.
import java.util.*;
class Number
{ //main method of the class
public static void main (String[] args) throws java.lang.Exception
{
try{
// create an array of size 50 of double type
double[] alpha = new double[50];
//initialize array
for(int x = 0; x< 50; x++)
{
if(x<25)
{
alpha[x]= x * x;
}
else
{
alpha[x]= 3 * x;
}
}
//print 10 elements per line
for(int y=1;y<=50;y++)
{
System.out.print(alpha[y-1] +" ");
if(y%10==0)
{
System.out.println();
}
}
}catch(Exception ex){
return;}
}
}
Explanation:
Create an array size 50 of double type.initialize first 25 elements as square
of the index variable and rest 25 as three times the index variable.Then print
the elements of array using for loop, if there is 10 elements in a line then
print a newline.
