The array is allow to store the multiple values but with same data type.
It cannot store element with different data type.
For example:
int array[] = {1, 'b', 8.7, 9, 'z'}

the correct ways is:
int array[] = {1,2,3,4};
float array[] = {1.2, 3.4, 9.6};

int size;
System.out.print("Enter the size : ");
size = scan.nextInt();
if(size>=1 && size<=20)
{
for(int i=0; i<size; i++)
{
for(int j=0; j<size; j++)
{
if(i==0 || j==0 || i==size-1 || j==size-1)
System.out.print("*");
else
System.out.print(" ");
}
