 // Java program to find whether the String

// has all same characters or not.

public class GFG{


static boolean allCharactersSame(String s)

{

int n = s.length();

for (int i = 1; i < n; i++)

if (s.charAt(i) != s.charAt(0))

return false;

return true;

}


// Driver code

static public void main (String[] args){

String s = "aaa";
