Write a Java program to check whether a specified character is happy or not. A character is happy when the same character appears to its left or right in a string.
Sample Solution:
Java Code:
import java.util.*;
public class Main
{
public boolean aCharacterIsHappy(String stng)
{
int l = stng.length();
boolean char_happy = true;
for (int i = 0; i < l; i++)
{
if (stng.charAt(i) == 'z')
{
if (i > 0 && stng.charAt(i-1) == 'z')
char_happy = true;
else if (i < l-1 && stng.charAt(i+1) == 'z')
char_happy = true;
else
char_happy = false;
}
}
return char_happy;
}
public static void main (String[] args)
{
Main m= new Main();
String str1 = "azzlea";
System.out.println("The given string is: "+str1);
System.out.println("Is Z happy in the string: "+m.aCharacterIsHappy(str1));
