class Square
{
public static void main(String args[])
{
int n=289,r;
r=sqrt(n);
if(n==r)
System.out.println("Perfect Square");
else
System.out.println("Not a Perfect Square");
}
}

Answer
Explanation
- Variable r must be of double type as Math.sqrt method returns a double value.
- The line
r=sqrt(n);should ber=Math.sqrt(n);
Corrected Program
class Square
{
public static void main(String args[])
{
int n=289;
double r=Math.sqrt(n); //1st & 2nd correction
if(n==r)
System.out.println("Perfect Square");
else
System.out.println("Not a Perfect Square");
}
}
