amazing ! thanks for your thorough explanations

u have not executed remaining iterations, simply escaped. when the method will exactly returned the reversed string to main method. the break point is may be the 1st condition, one time string will become null and it will return, but if string will become null then how it will hold the reversed string.

It would be better to do it using tail recursion as this recursion has pending operations. We might also get stackoverflow again if the length of string is huge.

Why we take private static class?can we take public method

Will this program run successfully if I don't use if else statement?

Sir program is giving stack overflow error.
Please correct me if there is any mistake in the code.
I am having interview tomorrow..please reply early

public class HelloWorld
{
public static void main(String []args)
{
String s= "Sandy";

}

private static String recursiveString(String st)
{
if(st==null)
{
if(st.length()<=1)
return st;
}

return
}
}
