Sample Solution:

Java Code:

import java.util.*;

// Define a class named Main
public class Main {

    // Method to exclude 'x' characters at the first two positions from the input string
    public String exceptTwoO(String stng) {
        String temp = ""; // Create an empty string

        // Iterate through each character in the input string
        for (int i = 0; i < stng.length(); i++) {
            // If the current index is 0 and the character is not 'x', append the character to the temporary string
            if (i == 0 && stng.charAt(i) != 'x')
                temp += stng.charAt(i);
            // If the current index is 1 and the character is not 'x', append the character to the temporary string
            else if (i == 1 && stng.charAt(i) != 'x')
                temp += stng.charAt(i);
            // If the current index is greater than 1, append the character to the temporary string
            else if (i > 1)
                temp += stng.charAt(i);
        }
        return temp; // Return the modified string
    }

    // Main method to execute the program
    public static void main(String[] args) {
        Main m = new Main(); // Create an instance of the Main class

        String str1 = "xxcyte"; // Input string

        // Display the given string and the new string using exceptTwoO method
        System.out.println("The given strings is: " + str1);
        System.out.println("The new string is: " + m.exceptTwoO(str1));
    }
}

Sample Output:

The given strings is: xxcyte
The new string is: cyte

public String exceptTwoO(String stng) 
{
  String temp = "";
  for (int i = 0; i < stng.length(); i++) 
  {
    if (i == 0 && stng.charAt(i) != 'o')
      temp += stng.charAt(i);
    else if (i == 1 && stng.charAt(i) != 'o')
      temp += stng.charAt(i);
    else if (i > 1)
      temp += stng.charAt(i);
  }
  return temp;
}
public static void main (String[] args)
    {
      Main m= new Main();
      String str1 =  "ooboat";
      System.out.println("The given strings is: "+str1);
      System.out.println("The new string is: "+m.exceptTwoO(str1));
	  }
}

Sample Output:

The given strings is: ooboat
The new string is: boat

Previous: Write a Java program to read a string and return the string without the first two characters. Keep the first character if it is 'g' and keep the second character if it is 'h'.
Next: Write a Java program to read a string and returns after removing a specified character and its immediate left and right characters.
