Java String Exercises: Read a string and return the string without the first two characters

Java String: Exercise-66 with Solution

Write a Java program to read a string and return the string without the first two characters.Except keep the first char if it is 'g' and keep the second char if it is 'h'.

Sample Solution:

Java Code:

import java.util.*;
public class Main
{
public String exceptFirstTwo(String stng) 
{   
  int len = stng.length();
  String temp = "";
  for (int i = 0; i < len; i++) 
  {
    if (i == 0 && stng.charAt(i) == 'g')
      temp += 'g';
    else if (i == 1 && stng.charAt(i) == 'h')
      temp += 'h';
    else if (i > 1)
      temp += stng.charAt(i);
  }
    return temp;
}
public static void main (String[] args)
    {
      Main m= new Main();
      String str1 =  "ghost";
      System.out.println("The given strings is: "+str1);
      System.out.println("The new string is: "+m.exceptFirstTwo(str1));
	  }
}
