Sample Solution:

Java Code:

import java.util.*;

// Define a class named Main
public class Main {

  // Method to remove all occurrences of 'z' from the string
  public String removeAllZ(String stng) {
    String fin_str = ""; // Initialize an empty string to store the modified string
    int l = stng.length(); // Get the length of the given string

    // Loop through each character of the string
    for (int i = 0; i < l; i++) {
      char temp = stng.charAt(i); // Get the character at the current index

      // Check if the character is not 'z' or if it's the first or last character in the string
      if (!(i > 0 && i < l - 1 && temp == 'z')) {
        fin_str = fin_str + temp; // Append the character to the final string
      }
    }
    return fin_str; // Return the modified string with 'z' removed
  }

  // 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 = "zebrazone"; // Given string
    // Display the given string and the new string after removing 'z'
    System.out.println("The given string is: " + str1);
    System.out.println("The new string is: " + m.removeAllZ(str1));
  }
}

Sample Output:

The given string is: zebrazone
The new string is: zebraone

Previous: Write a Java program to return the sum of the digits present in the given string.If there is no digits the sum return is 0.
Next: Write a Java program to return a string with the characters of the index position 0,1,2, 5,6,7, ... from a given string.
