can any one give me the source code using java?
Write a function named isSquare that returns 1 if its integer argument is a square of some integer, otherwise it returns 0. Your function must not use any function or method (e.g. sqrt) that comes with a runtime library or class library!
The signature of the function is
int isSquare(int n)
Examples:
if n is return reason
4 1 because 4 = 2*2
25 1 because 25 = 5*5/td>
-4 0 because there is no integer that when squared equals -4. (note, -2 squared is 4)
8 0 because the square root of 8 is not an integer.
0 1 because 0 = 0*0

Answer Wiki:
If you cannot use ANY function, your function should look something like this:
<pre> public int isSquare (int n) {
int iRootTest = 1;
int iSquareTest = 0;
if (n == 0 || n == 1)
return 1;
while (iSquareTest <= n) {
iSquareTest = iRootTest*iRootTest;
if (iSquareTest == n)
return 1;
iRootTest += 1;
};
return 0;
};</pre>
This function will try any integer starting from 1 until the square of that integer is equal or greater than n. If it is equal, then return 1, and when it is bigger exits from the loop and return 0;
